A Microsoft file hosting and synchronization service.
Quite same story here in our tenant. Recently migrated last batch of 150 users on total of 200 users to 365. Not sure whether issue/bug is new or was there for a longer period of time, but as majority of recently joined (150+) users are more 'active' on .xlsx, .docx and .pptx only by now these issues reached my inbox.
I'm currently in a support-ticket with Microsoft so will post progress in this topic as well FYI, but untill now no progress made: will set-up a VM to replicate the issue for them to screenrecord steps for their technical-dept.
Scenario described step-by-step here:
-
- Office files (docX, xlsX, pptX) are stored within a Teams channel
-
- Channel is linked as shortcut to Onedrive
-
- Onedrive is installed+linked to local drive
- When opening a xlsX file straight from Explorer > Onedrive, the file opens in local Excel app with AutoSave INACTIVE.
- When opening that same file from within Teams (New) Desktop App, the file opens in local Excel app with AutoSave ON.
- In our org lots and lots of duplicate Office files are arising, as staff primarily uses local Onedrive/Explorer to navigate through their files.
- As such, they know they have to enable AutoSave, but as such the unaware create for each handled file a duplicate file in their Onedrive store instead on the original Teams Channel.
- Workaround for now is alert staff to open files from Teams in their local Office Desktop app to avoid mistakes.
