Check for Microsoft Teams Update with PowerShell

Andres Bohren
Hi All,

I was inspired to look a little bit deeper into the Update Mechanism of Microsoft Teams by the "Teams MSI Override" GitHub Project.

You can check your Version in Teams by Settings > Info > Version


Then the current Version and update Date is shown in the top bar


You can invoke a update check in Settings > check for updates


Then Teams will search for updates


I've traced this Action in Fiddler


Now you can do your own Check in PowerShell

$Version = "1.5.00.1870"
$Url = "https://teams.microsoft.com/desktopclient/update/$Version/windows/x64?ring=general"

Write-Host "Sending request to $Url"
$updateCheckResponse = Invoke-WebRequest -Uri $Url -UseBasicParsing
$updateCheckJson = $updateCheckResponse | ConvertFrom-Json
$updateCheckJson


If you send the Current Version you get nothing back - this means there is no update available

$Version = "1.5.00.4767"
$Url = "https://teams.microsoft.com/desktopclient/update/$Version/windows/x64?ring=general"

Write-Host "Sending request to $Url"
$updateCheckResponse = Invoke-WebRequest -Uri $Url -UseBasicParsing
$updateCheckJson = $updateCheckResponse | ConvertFrom-Json
$updateCheckJson


Or you can check for OSX Updates

$Version = "1.5.00.00000"
$Url = "https://teams.microsoft.com/package/desktopclient/update/$Version/osx/x64?ring=general"

Write-Host "Sending request to $Url"
$updateCheckResponse = Invoke-WebRequest -Uri $Url -UseBasicParsing
$updateCheckJson = $updateCheckResponse | ConvertFrom-Json
$updateCheckJson
