I know most people out there cringe at the thought of spending time packaging applications for deployment, but unfortunately I seem to be a sucker for punishment and really do revel in the challenges faced with application packaging!
Here’s a nice and easy one that will help anyone tasked with getting the latest version of the Teams client onto devices – whether using SCCM or Intune, you will find a use for the code below.
The version release cycle of Microsoft Teams is rapid – so much so that if you were tasked with maintaining the latest installation media for your business deployment solution, you’ll very quickly find that it would take up a lot of your time just keeping your local repositories up to date. Of course, the client itself has a very robust update engine, so it *technically* doesn’t matter what version you initially install, for sanity’s sake and for a little bit more control, it’s best to try and start with the latest version.
The trick here is to not worry about maintaining a local version of the installation media and simply force the device to pull down the latest version from the official repo!
Onto the solution!
After a bit of digging and monitoring with fiddler on the Teams download page, I identified the way the URLs were being formed to request the correct media. Below is a breakdown.
Base URL: https://teams.microsoft.com/downloads/DesktopURL?
Quite straightforward! So if we want to pull down the latest Windows 64-bit client, we simply create the URL shown below:
So now lets throw that URL into a powershell web-request…
And the result of that command below..
Success! if we have a look at the content of the result of the web-request we can see the URL of the latest 64-bit Teams client!
Now that we know the process to retrieve the media, we can turn the whole process into a function that can be deployed out to devices to pull down the install media.
Below is the function I have created to programatically form the correct URL based on our requirements – aside from creating the URL and capturing the file URL, all that is left to be done is pull down the content using Bits & a little bit of error handling!
Now that you have a function to easily retrieve the latest installation media, all that is required is to handle the installation which of course will vary between operating systems.
Once you have a working installation script, it’s then a piece of cake to deploy via sidecar in Intune (or SCCM – any deployment method will suffice!)
I’ve provided a fully functioning example to download and install the latest 64-bit Client for windows in my GitHub repository for your preusal / review.
