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.

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

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,

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

Hi Marvin, sorry for the delay in my response.

I downloaded the Microsoft Support and Recovery Assistant but it doesn't seem to repair a thing, I mean, it says that is scanning but it takes +2 hrs. and shows no changes at all. I have also tried re installing MS Office and it has gone well but it doesn't solve my problem.

I'm currently downloading my filles locally, work on them and then uploading them to teams, I have no issues with this but it is very complicated as my work consists in modify slides in massive presentations with my team.
