Imagine the situation, a family member befriends you on Facebook and you foolishly accept, then find their replies on your posts to be inappropriate or annoying… after all, you can choose your friends but not your family, right?Well, it turns out that

Well, it turns out that Facebook has a feature for situations like this – the Restricted list.

“Putting someone on the Restricted list means that you’re still friends, but that you only share your posts with them when you choose Public as the audience, or when you tag them in the post.

For example, if you’re friends with your boss and you put them on your Restricted list, then post a photo and choose Friends as the audience, you aren’t sharing that photo with your boss, or anyone else on your Restricted list. However, if you tag your boss in the photo, or chose Public as the audience, they’ll be able to see the photo.”

Last night, whilst working in the Premier Inn close to the office, I noticed the browser going to an interesting URI after I connected to the hotel Wi-Fi.  That URI was http://www.msftconnecttest.com/redirect and a little more research tells me it’s used by Windows 10 to detect whether the PC has an Internet connection or not.

The feature is actually the Network Connection Status Icon (NCSI) and, more accurately, the URIs used are:

The URI I saw actually redirects to MSN whereas the ones above return static text to indicate a successful connection.

For those who want to know more, there’s a detailed technical reference on TechNet, which dates back to Windows Vista and an extensive blog post on the Network Connection Status Icon.

Do we need another as-a-service to describe functions?

Last week saw quarterly earnings reports for major cloud vendors and this tweet caught my eye:

You see, despite Azure growing by 93%, this suggests that Amazon has the cloud market sewn up. Except I’m not sure they do…

I think it would be interesting to see this separated into infrastructure-, platform- and software-as-a-service (IaaS/PaaS/SaaS). I suggest that would present three very different stories. And I’d expect that Amazon would only really be way out front for IaaS.

My friend and former colleague, Garry Martin (@GarryMartin) questioned the relevance of those “legacy” distinctions but I think they still have value today.

In the early days of what we now recognise as cloud computing, every vendor was applying their own brand of cloud-washing. It still happens today, with vendors claiming to offer IaaS when really they have a hosted service and a traditional delivery model.

Back in 2011, the US National Institute of Standards and Technology (NIST) defined cloud computing, including the service models of IaaS, PaaS and SaaS. Those service models, along with the (also abused) deployment models (public cloud, private cloud, etc.) have served us well but are they really legacy?

I don’t think they are. Six years is a long time in IT, let alone the cloud but I think IaaS, PaaS and SaaS are as relevant today as they were when NIST wrote their definition.

When asked how “serverless” technologies like AWS Lambda, Azure Functions or Google Cloud Functions fit in, I say they’re just PaaS. Done right.

Some people want to add another service model/definition for Function-as-a-Service (FaaS). But why? What value does it add? Functions are just PaaS but we’ve finally evolved to a place where we are moving past the point of caring about what the code runs on and letting the cloud manage that for us. That’s what PaaS has supposed to have been doing for years (after all, should I really need to define a number of instances to run my web application – that all sounds a bit like virtual machines to me…)

To my mind, “serverless” is just the ultimate platform as a service and we really don’t need another service model to describe it.

To quote a haiku from Onsi Fakhouri (@onsijoe):

“Here is my code
Run it in the cloud for me
I don’t care how”

Or, as Simon Wardley (@swardley) “fixed” this Cloud Foundry diagram:

Outlook gotcha: only cached data is exported to data file (.PST)

This weekend, a family project that required its own mailbox ended, meaning I could reduce the number of licences in my Exchange Online subscription. That’s straightforward enough but I wanted to take a backup copy of the email before cutting the mailbox loose.

From the last time I did any Exchange Online administration, I recalled that one of the limitations was that you can’t back up a mailbox to a PST from PowerShell. That may have changed but the advice at the time was to backup to an Outlook data file (also known as a Personal Folder) in Outlook. It’s clunky but at least it’s functional.

I couldn’t work out why not all of the data was being exported; only the items that were cached and not the ones that appeared if I clicked on “There are more items in this folder on the server/click here to view more on Microsoft Exchange”. Then I found a clue in a Spiceworks post from Joe Fenninger, where Joe says “Dont [sic] forget to download all [Office 365] content prior to export.”.

I needed to adjust the cached mode settings for the mailbox to change how much email is kept offline, after which Outlook could export all items to the Outlook Data File, rather than just the ones that were cached locally.

The effects of cybercrime are tremendous, impacting a company’s financial standing, reputation and ultimately its ability to provide security of employment to its staff. Nevertheless, organisations can protect themselves. Mitigating the risks of cyber-attack can be achieved by applying people, process and technology to reduce the possibility of attack.

Fellow risual architect Tim Siddle (@tim_siddle) and I have published a white paper that looks at how Microsoft technology can be used to secure the modern productive enterprise. The tools we describe are part of Office 365, Enterprise Mobility + Security, or enterprise editions of Windows 10. Together they can replace many point solutions and provide a holistic view, drawing on Microsoft’s massive intelligent security graph.

Generating a GPX file for Strava after the tech let me down

This afternoon was glorious. The sun was shining and, even though it was a work day, the company I work for had arranged an afternoon out for staff at Cannock Chase (Go Ape). High ropes, Forest Segway, or Mountain biking activities were all available – right up my street!

I decided I’d like to Segway but I was in the second group (which meant waiting around for an hour or so), so I took a bike out for a little ride whilst I was waiting. Unfortunately, I didn’t have my Garmin with me and my iPhone’s attempts to capture my movements on Strava were woeful.

Shortly after setting off on “Follow The Dog“, I lost the rest of the group (whilst messing around with Strava!) and decided that I would rather come back and ride another day with my son than ride on my own and (potentially) miss the Segway opportunity. But I still wanted to capture the details of the (admittedly short) ride…

Generating a GPX file to upload to Strava is straightforward enough – I used Mapometer for that. Unfortunately though, Strava won’t allow GPX files without time information to be uploaded.

The workaround is to estimate some time data and insert it in the file – which is where the excellent Gotoes site helped! Goetoes has several utilities for Strava and Garmin Connect including:

  • Combining FIT, GPX or TCX files
  • Merging heart rate and position files (FIT/TCX)
  • A bookmarklet to export GPX from Garmin Connect
  • The ability to upload to Strava via email

and…

Using this with an estimate of my time, a known distance (so an estimated speed) and Gotoes’ ability to work out what my speed might have been at different points on the route came up with something approximate to put into Strava. I’ve hidden it from leaderboards – because it’s “fake data” – but it’s enough for me to track the distance and the fact I did go for a little bimble.

Strangely, the iPhone’s GPS performed OK for the Segway ride (which I’ve recorded as an eBike and alse hidden from leaderboards):

“You need to work less”. Musings on finding the elusive work-life balance

“You need to work less”, said David Hughes (@davidhughes) as we were discussing why I carried a power supply with my Surface Pro. This was in response to my observation that the device will get me through the work day but not through travel at each end as well.

“Actually, you have a point”, I thought. You see, weekdays are pretty much devoted to work and pseudo-work (blogging, social media, keeping up to date with tech, etc.) – except for meals, sleep, the couple of hours a week spent exercising, and a bit of TV in the evening.

David commented that he reads – rather than working – on the train (I tweet and email but really should read more). And when I asked how he organises his day, he introduced me to ToDoIst. It seems that having a task list is one thing but having a task list that can work for you is something else.

Today was different. I knew I wanted to get a blog post out this morning, finish writing a white paper, and find time to break and meet with David in my favourite coffee shop. I’m terrible at getting up on working-from-home days (more typically working well into the evening instead) but I had managed to be at my desk by 7am and that meant that when I left the house mid-morning I’d already got half a day’s work in. For once, I’d managed some semblance of work-life balance. The afternoon was still pretty tough and I’m still working as we approach 7pm (my over-caffeinated state wasn’t good for writing!) but I met my objectives for the day.

Now I’ve added ToDoIst to my workflow I’m hoping to be more focused, to wrap up each day and set priorities for the next. I need to stop trying to squeeze as much as I can into an ever-more-frantic existence and to be ruthless with what can and can’t be achieved. Time will tell how successful I am, but it feels better already.

My first PowerApps app – a business mileage recorder

Posted on By Mark Wilson
This content is 8 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.

In common with many people who travel for work, I keep a record of my journeys so that I can claim mileage expenses. For the last couple of years, that record has been a spiral-bound notebook (for driving) and Strava (for cycling) – though I haven’t actually claimed any mileage for cycling yet! I wanted to replace my analogue system with a smartphone app and, following a conversation a few weeks ago with my colleague Brian Cain (@BrianCainUC), I decided to create something using Microsoft PowerApps.

For those who are unfamiliar with PowerApps, it’s a technology solution provided by Microsoft to help normal business users – people who are not developers – to create simple applications to connect systems and data. The resulting apps can run on mobile devices, as well as on Windows 10.

PowerApps is available in my Office 365 subscription (though I think there are other ways to sign-up too) and I set to work creating my Mileage Recorder. A few minutes later I had something functional. Not long after that I had tweaked it to be pretty much what I needed. So I created an app in less than 30 minutes and it’s taken me three weeks to write this blog post! Hmm…

Creating my first PowerApps app

My app is a simple three-screen app – taking a table in an Excel Workbook from OneDrive for Business as a data source. PowerApps recognised the data types in the columns of the table and formatted accordingly, then I tweaked things a little in PowerApps Studio.

PowerApps Mileage Recorder: Home PowerApps Mileage Recorder: View PowerApps Mileage Recorder: Edit

I haven’t looked in detail at the architecture used by PowerApps but essentially the PowerApps app provides a native OS wrapper for any apps that I create. This means my app will work on any platform where PowerApps is supported.

PowerApps Mileage Recorder

I can also create a direct link to the app on my phone’s home screen but the look and feel is one of a PowerApps app – not a native application. None of that is an issue – if I want more complex cross-platform apps then someone who can cut code (not me!) can use Xamarin – but for a simple app, PowerApps seems to do the job.

PowerApps/Mileage Recorder on iOS Home Screen

The PowerApps documentation helped me out a lot – and these were the tutorials I found most useful:

There’s also a useful Q&A on using PowerApps within an organisation.

I did have some challenges worth noting but none are show-stoppers:

  • The Windows 10 smartphone that I use for work doesn’t meet the PowerApps hardware requirements, which is a little bizarre. So, I needed to use the app on my personal iPhone. I had created my PowerApp using my employer’s Office 365 tenant and a data source in my work OneDrive but I also use the Outlook app on iOS to connect to my personal Office 365 tenant. This combination was causing challenges that required re-authentication. I couldn’t find an easy way to move the app between tenants (though I’m sure there is one) so I moved the data source to my own tenant and recreated the PowerApp. I’m pretty sure that there must be a proper way to import and export apps, I just haven’t found it yet!
  • The web version of the PowerApps Studio seems a bit flaky at times but it is still a preview. Installing the Universal Windows Platform (UWP) version on a Windows 10 PC worked flawlessly though, even without any admin rights on my company Surface.
  • I couldn’t work out how to make a date and time field work as a simple date field. I really don’t need to record the time of my journeys – just the date!
  • PowerApps doesn’t support formulae in Excel workbooks. Instead, I had to apply some logic in the app to calculate the miles travelled, which displays in my app but doesn’t get written back to the data source. I’m pretty sure that’s fixable – I just haven’t worked out how, yet…

Is it really a good idea to let users create their own apps?

In my customer conversations, it’s quite common to hear IT people saying they don’t want their users creating PowerApps. I can see why – after all, we’ve all seen Access databases and Excel spreadsheets become “business-critical applications” that then create issues for the IT department. For what it’s worth, my view is that if something is really business critical, the business will invest resources into developing something that’s properly supportable. If it doesn’t reach that bar, then it’s not a business-critical app – and why would you prevent users from generating their own tools that help them to work more effectively, albeit unsupported by corporate IT?

To put it another way, people will do what they need to do to get things done, with or without IT’s blessing – so why not give them the tools to do things in a manner that integrates well with existing (supported) applications and services?

I’ll be at Microsoft tomorrow, attending a training event around PowerApps and Flow. That should give me a good opportunity to build on the experience from creating my Mileage Recorder. Together with PowerBI (something else I really need to learn more about) these technologies provide a trilogy of tools to empower users to do more with data. And on that note, I should probably end this blog post, as I’m starting to sound like a Microsoft marketing representative…

Removing the ability to accidentally email colleagues from my personal mailbox in Office 365

Posted on By Mark Wilson
This content is 8 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.

For some time now, Outlook has supported the use of multiple Exchange servers inside a single profile. This is very useful because I can use a single client to connect to my work email (@risual.com), my Microsoft email (until recently), any email accounts that are provided by customers (e.g. for project purposes) and my personal email account.

There are a couple of gotchas though:

  • My employer uses Azure Information Protection (AIP) to classify email and the AIP client will not allow me to send a message unless it’s classified, regardless of whether I’m sending using my risual.com account or one of the others.
  • I have to be careful to make sure that I don’t accidentally send business email from my personal account. This isn’t a problem when responding to an existing message but is possible if the focus is on my personal Inbox and I start a new message thinking “I just need to email so-and-so about something-or-other” (often out of hours).

The first of these is just a minor inconvenience – I just send as Unclassified if I’m not using my risual.com account. The second requires a little more thought – and my colleague Simon Bilton (@sabrisual) suggested creating a transport rule in Exchange Online (who said Engagement Managers aren’t technical?).

So, as of now, the following rule is in place:

<?xml version="1.0" encoding="utf-16" standalone="yes"?>
<rules name="TransportVersioned">
  <rule name="Prevent accidentally sending work email from personal account" id="a0f59e36-93f1-4f2e-bccb-3eddf0c097e1" format="cmdlet">
    <version requiredMinVersion="15.0.3.0">
      <commandBlock><![CDATA[New-TransportRule -Name 'Prevent accidentally sending work email from personal account' -Comments '
' -Mode Enforce -RecipientAddressContainsWords 'risual.com' -ExceptIfSentTo 'markw@risual.com' -SetAuditSeverity 'High' -RejectMessageReasonText 'This email contains recipients at risual.com and you are sending from your personal account' -RejectMessageEnhancedStatusCode '5.7.1']]></commandBlock>
    </version>
  </rule>
</rules>

This rejects email sent from my Exchange Online subscription to any risual.com address except markw@risual.com. That exception allows my wife (on the same server) to send email to me and still allows me to forward emails to myself at work (e.g. receipts for expenses using my personal email address).

I’ve tested by sending to both markw@risual.com (allowed) and mark@risual.com (blocked) so accidentally emailing someone at work from my personal address is no longer a concern!

Custom mail flow rule blocks email sent to work from personal mailbox

Office 365 data moves are now available for UK customers

Posted on By Mark Wilson

Last year I wrote a post about data residency options for Office 365 customers in the UK. At the time, Microsoft was publishing a window for UK-based customers to request data moves between December 2016 and February 2017 but then the web page was updated to say “TBA”. Now, the how to request your data move page has been updated again (thanks to @gavinmorrison for the tip-off), giving UK customers six months between 15 March 2017 and 15 September 2017 to request a move to UK-hosting. Microsoft will then take up to 2 years to complete the move.

This is a one-time opportunity to request a data move (although tenants created after UK datacenter availability will already be hosted in the UK) but it’s only recommended if your organisation has strict data residency requirements. If you don’t see the option to move, it’s probably because:

  • You’re using the old Office 365 Admin Center – the option is only available (under Settings, Organization Profile, Data Residency Option) in the preview Admin Center.
  • Your tenant is not eligible for the move.
  • All of your data is already located in the new region.

Once you’ve started the move process, it cannot be cancelled.
