Can't open files from Teams in Office desktop app

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.

    Thanks Marvin, I've tried both suggested solutions (office apps are related and the thing of deleting items from the Teams folder) but it didn't solve my problem. I can see the app window opening and loading but then it disappears and then nothing happens. I've checked the task manager to see if the app is running but it's not listed in the processes tab.

    Hi Dave,

    Based on your description, when you try to open Word or Excel files in Teams, it fails to call Word or Excel desktop app. As far as I know, when you try to open the files in desktop app, it will use the URL protocol to open the related Office desktop app. In this scenario, please go to Settings > Apps & features > Default apps > Choose default apps by protocol, then scroll down and check if Excel is selected as the default app for MS-EXCEL.

    Besides, regarding clear the cache in Teams folder, did you mean the following steps? If not, please make a try.

    1. Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’, or run Task Manager and fully kill the process.
    2. Go to File Explorer, and type in %appdata%\Microsoft\teams.
    3. Once in the directory, delete all files and restart Teams.

    Regards,

    Marvin
