Can't open files from Teams in Office desktop app

Anonymous

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.

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!!

My students have all the same problem as you've described, Dave.

I've read the answers of Marvin, and it's typical nonsense; uninstall, reinstall, check version, get updates. This is clearly a problem with Microsoft, but instead of addressing the issue AND getting someone who actually knows what's to be done, you get someone following a list of suggestions, which, by the way, is the same for all problems related to the Microsoft suite and rarely works.

I'll keep looking for a solution and get back to you when I can.

Cheers,

Really annoyed

Hi Marvin

I am having almost the exact issue but only with PowerPoint

Choosing the option Open in desktop appfor Powerpoint whether in MS Teams Desktop, Web, or Sharepoint has since ~mid February resulted in the following error

"This action couldn't be performed because Office encountered an error. Running repair may help. If this problem persists, repair your product within the Control Panel"

I have tried repairing as recommended, deleting and then re-installing, using Microsoft Support and Recovery Assistant, etc... but nothing seems to work and I'm basically at my wits end

I can't understand why every other Office application is working except powerpoint.

Please help

Ken

Hi Dave,

Sorry for the late reply. I've submitted the log file to our related engineering team. However currently I haven't received response them. I'll try to further contact them to check if there's any progress on this issue. Thank you for your kind understanding.

Regards,

Marvin

Hi Dave,

If the app window is initiated successfully, it indicates the request to call Word and Excel apps is working. In this scenario, the issue could be related with the file opening/accessing. Please first make sure your Office apps are updated to the latest version. For your reference, see Update history for Office 365 ProPlus. If it's already the latest version, please try to run Office Repair to check if it helps.

Besides, if you download the files to local, then open the files directly via Word or Excel app, will it work?

Regards,

Marvin
