Fix Outlook Sign-In Errors in Excel During AutoSave
Question details
The user needs to resolve an issue where Excel repeatedly fails to authenticate with Outlook or OneDrive, preventing the AutoSave feature from working.
- Product
- Excel
- Device & OS
- Mac
- Scenario
- Attempting to use the AutoSave feature in Excel, which requires an active connection to OneDrive or Outlook.
- Observed behavior
- The application gets stuck in an authentication loop or continuously fails to sign in, stopping the file from autosaving to the cloud.
Ensure you have a stable internet connection and verify that your Microsoft account credentials are correct before troubleshooting the authentication loop.
Use an InPrivate or Incognito Window
Using a private browsing window bypasses existing cache and cookie conflicts, allowing for a clean login attempt to Microsoft services.
Authentication errors in Office apps are frequently tied to conflicting login sessions in your default web browser. Using an InPrivate window forces the system to prompt for fresh credentials.
Launch the Microsoft Edge browser on your device.
Click the 'Settings and more' menu (the three dots icon in the upper right corner) and select 'New InPrivate window'.
Navigate to OneDrive or Outlook via the web in this private window and enter your login details to confirm your credentials work without errors.
Clear Browser Cache and Microsoft Cookies
Clearing outdated or corrupted cookies can permanently resolve repeated authentication loops during the Excel sign-in process.
Isolate the Authentication Error
Determine if the sign-in failure is specific to the Excel desktop application or a broader issue with your web environment.

Frequently Asked Questions
Why does Excel AutoSave require an Outlook or OneDrive sign-in?
The AutoSave feature specifically syncs your real-time document edits to Microsoft's cloud services (OneDrive or SharePoint). To authorize these uploads, Excel requires an active, authenticated connection to your Microsoft account.
Does clearing browser cookies affect my Excel desktop application?
Yes. Microsoft Office desktop apps often use embedded web browser components or rely on your system's default browser to display the login screens. Clearing corrupted cookies in the browser can fix authentication loops inside the app.
How do I know if the sign-in error is a browser issue or an app issue?
Try logging into OneDrive via a web browser. If you can log in successfully on the web without any errors, the problem is likely isolated to the Excel app's cached credentials. If it fails on the web as well, it may be an account or server issue.
