I've been using MS Teams to work with PowerPoint and Excel documents with the option Open in desktop app. Until a few weeks ago when I try to open a document with the option open desktop app I get the launching window of the app (any office app like Excel, Powr Point, Word, etc.) but it doesn't start anything. This is with all the files I try. I haven't made changes to my settings or anything. I have tried to clear the cache in the Teams Folder and I have checked that the apps are linked to the right file types but nothing works. I also have looked on the official site for help and in this community but I can't find any fixes that solve this.
Additional features, settings, or issues not covered by specific Microsoft Teams categories

Thanks...It was a new laptop out of the box yesterday so all the software was 100% up to date. In the end I gave up and did a full Microsoft Repair and reinstalled all the software which then worked...
In my case the connection between Teams starting up PPT was broken. Teams uses 'url' startup connection (look at Control Panel - Standard app file type overview. And I could not add this connection. I ran an Office repair (https://support.microsoft.com/nl-nl/office/office-programma-s-herstellen-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b?ui=nl-nl&rs=nl-nl&ad=nl) and it was corrected again.
Hi, please provide the solution for this. The problem still persist after re-installed Teams and Office.
Windows Version: Windows 10 Pro Version 1909
Teams Version: 1.3.00.28779
Office Version: Microsoft Office 365 ProPlus
You need to repair Microsoft app.
Go to Settings > Apps> Apps & Features. Look for the Microsoft App ( In my case, it's Microsoft 365 App). Click on it and click modify. IT's going to ask you to see if you allow the app to make changes. Click "Yes" and click on the Online Repair. Once the repairing is done, reboot your system and you should be good to go!!
