Frequently Asked Questions

Will I lose my local files if the OneDrive folder disappears during installation?

No, you will not lose any data. The folder may temporarily disappear from your Finder sidebar because the Microsoft 365 installer closes the active OneDrive app. Your files remain safe in the cloud and locally, and the folder will automatically reappear once you relaunch OneDrive.

Can I have two personal OneDrive accounts logged in at the same time on Mac?

No. The OneDrive app for Mac only allows you to have two accounts open simultaneously if they are of different types: one must be a personal account and the other must be a corporate (work or school) account.

Do I need to uninstall my old Office version before installing Microsoft 365 Personal?

While it is not strictly required, it is highly recommended to completely remove older, unsupported versions of Microsoft Office from your Mac before installing Microsoft 365 to prevent software conflicts and ensure optimal performance.
