We have a strange one and not sure if this is Teams related or SharePoint so here goes. This happens to a few users all using Teams collaboration with PowerPoint. They are all using Windows 10 1709 and Teams Desktop. When we open PowerPoint files from within Teams we select open in PowerPoint. This opens the file with the local PowerPoint app. We can be using the app for 10 mins or a few hours then suddenly it closes. It doesn't crash or give any warning, it just closes. Its like clicking the exit cross but we're not. Its affecting multiple users on different hardware. I've checked Events and nothing.
The reason I'm aiming it at Teams is it inst happening if I open a file from desktop or docs etc. Its only doing it from Teams.
Yeah I thought the same. People only started reporting the issue when we moved the files into Teams. SInce then we've had 4 reports with one user reporting it everyday. We moved the files back to desktop and hasnt had the problem since. We then took a user who wasnt using Teams and didnt have any issues. We put a few files into Teams and instantly started seeing the problem. Strange one.
