- Scenario
- Trying to AutoSave new files or access previously saved documents using OneDrive in Office for Mac.
- Observed behavior

Switch to a New Microsoft 365 Account in Office
Resolve the AutoSave issue by signing out of the inaccessible account and connecting your active Microsoft 365 profile.
Office for Mac relies on the Microsoft account currently signed into the application to manage OneDrive AutoSave. By switching the active account, you can restore AutoSave functionality for new documents.
Launch any Office application on your Mac, such as Microsoft Word or Excel.
Click on the application name (e.g., 'Word') in the top menu bar and select 'Sign Out', or click on your profile picture/name in the top-left corner of the document gallery and choose 'Sign Out'.
Completely quit the Office application and then open it again to ensure the old session is fully cleared.
Click 'Sign In' on the welcome screen or in the top-left corner and enter the credentials for your new, active Microsoft 365 account.
Recover the Old Microsoft Account
If you need access to your previously saved documents, you must recover the old account using Microsoft's web tools.

- 2. Install WPS Office: Open the downloaded file and drag the WPS Office icon into your Applications folder.
- 3. Open your files: Launch WPS Office and directly open your existing Word, Excel, or PowerPoint files without worrying about complex account linking.

Frequently Asked Questions
Will I lose my files if I sign out of my old OneDrive account on Mac?
Signing out does not delete your files, but it will remove your access to them within the Office application until you sign back into that specific account or recover it online.
Can I merge my old OneDrive account with a new one?
Microsoft does not offer a direct way to merge two OneDrive accounts. You must manually download the files from the old account and upload them to the new one.
Why is my AutoSave toggle disabled in Word for Mac?
The AutoSave feature only works when your document is saved to a cloud service like OneDrive or SharePoint. If you are not signed in, or if the linked account is inaccessible, the AutoSave toggle will remain grayed out.
