Additional file-related features and issues within Microsoft Teams for business
Hi,
We would like to report that we have the same issue in one of our environments and are also investigating this on our end.
From our end we are checking if the requirements of this learn document are met
Desktop app option is missing when editing Office files in Teams - Microsoft Teams | Microsoft Learn
On our side we can at least confirm the following:
- Latest version of Teams has been installed
- Latest version of Office has been installed
- Licenses have been correctly assigned to the users
The last step asks you to check if "O365ProPlusRetail" Product ID is present by running a powershell command. If this is not the case, a full removal of all Office applications from the computer and a reinstall from the microsoft portal may be the way forward.
after some checking we also found the following topic: Microsoft Teams - "Open with the desktop app" default setting has - Microsoft Community
they asked to check the following registry key: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration and Look on the right for "ProductReleaseIds"
Older installed or prepackaged installs could have an unsupported ReleaseID and should be changed to "O365ProPlusRetail" for this option to work.
We will be checking this on our end and providing feedback.
