Teams: Check client version using PowerShell

An easy way to check MS Teams version is in the client by going to About > Version:

The version will be displayed near the Command Box:

The MS Teams client is installed per user and the version is stored in the settings.json file:


Using PowerShell we can convert JSON files to PowerShell Objects:

Now we can run the following PowerShell cmdlet to get the Teams client version:

Get-Content $env:UserProfile”\AppData\Roaming\Microsoft\Teams\settings.json” | ConvertFrom-Json | Select Version, Ring, Environment

The install/update date is in the installTime.txt file in the same folder:

Get-Content $env:UserProfile”\AppData\Roaming\Microsoft\Teams\installTime.txt”

Note: The date is stored in MM/dd/yyyy

Since MS Teams is installed on a user level we can have multiple versions on the same machine.

To check all the installed versions we can use a PowerShell Script that will execute the previous cmdlets for each user.

The script is available in TechNet Gallery and doesn’t take any parameter:

MS Teams installed version for each user profile

PSScript: Lync/SfB Server Certification Store Validation

In a previous post, we published the checks/validations that we should do in the Certification Store in the Lync/SfB servers.

Checks to do in the Lync/SfB Certificate Store

We decided to write a PowerShell with all these checks to make it simple to use. The script will be kept in sync with the post, meaning that when a new check is added, it will also be included in the script.

The PowerShell script is available in the TechNet Gallery:

Both script usage and change log are included in the TechNet Gallery description.
