Device & OS: not provided
Scenario: Synchronizing Microsoft 365 business notebooks to the cloud.

Solution 1Recommended

Remove Conflicting Microsoft Accounts

Signing out of personal or unrelated accounts ensures OneNote correctly authenticates your Microsoft 365 Business account for syncing.

Account authentication conflicts frequently occur when both a personal Microsoft account and a business account are logged into the same Office application.

Open Account Settings

Launch OneNote, click on the 'File' tab in the top-left corner of the window, and select 'Account' from the left-hand menu.

Sign Out of Unrelated Accounts

Click on 'Switch account' to view all connected accounts. Manually sign out of any personal or secondary Microsoft accounts listed.

Isolate the Business Account

Ensure that only your designated Microsoft 365 Business account remains signed in under the Connected Services section.

Restart and Sync

Close the OneNote application completely. Reopen OneNote and manually trigger a notebook sync to verify the issue is resolved.

Sync Restored: Once the conflicting accounts are removed, OneNote should automatically resume syncing your business notebooks without looping the sign-in prompt.

Solution 2

Contact Microsoft 365 Support

If resolving local account conflicts does not work, the issue may require backend intervention from Microsoft support.

Frequently Asked Questions

Why does OneNote keep asking me to sign in repeatedly?

This usually occurs when cached login credentials expire, become corrupted, or when there is an authentication conflict between a personal Microsoft account and a business/school account logged into the same app.

Will signing out of OneNote delete my un-synced notes?

Un-synced notes may be lost if you sign out or close the notebook before synchronization completes. It is highly recommended to manually copy and paste un-synced content to a local document (like Word or Notepad) before signing out.

Can I use personal and business accounts in OneNote simultaneously?

Yes, OneNote generally supports adding multiple accounts. However, authentication conflicts can sometimes cause sync errors. Temporarily signing out of the secondary accounts is a standard troubleshooting step to resolve these conflicts.
