Question details

The user experiences a recurring 'Saved offline (sign-in required)' error in OneNote, forcing them to sign in every day to sync notebooks.

How to Fix the OneNote 'Saved Offline' Sign-In Error

Product: Microsoft OneNote
Device & OS: Windows
Scenario: Attempting to sync OneNote notebooks while logged in with multiple Microsoft 365 accounts, such as a personal and a university-managed license.
Observed behavior: OneNote repeatedly fails to sync automatically, displays a 'Saved offline' message, and prompts the user for a new sign-in daily.

Before you start

Back up any unsynchronized notebook content by manually copying and pasting it to a local document (such as Word or Notepad), as unsynced notes will be permanently lost when you sign out or reset credentials.

Solution 1Recommended

Clear Office Credentials in Windows Credential Manager

Removing corrupted or conflicting Microsoft Office credentials forces OneNote to prompt for a clean, authenticated sign-in.

Sign out of Office

In OneNote, close each notebook, sign out of all Microsoft 365 accounts, and quit all Microsoft Office applications completely.

Open Credential Manager

Click the Windows Start button, type 'Credential Manager' into the search bar, and open the app from the Control Panel.

Remove Windows Credentials

Navigate to the 'Windows Credentials' tab. Locate all entries that start with 'MicrosoftOffice', click on the drop-down arrow next to each, and select 'Remove'.

Restart and sign in

Restart your computer, open OneNote, and sign in again using the email account associated with your active Microsoft 365 license.

Clear Office Credentials in Windows Credential Manager

Verify Sync Status: After signing in, verify that your notebooks are syncing properly by checking for the green sync icon next to your notebook name.

Solution 2

Reset Microsoft Office Identity and Cache Data

Clear corrupted local identity caches and registry keys to resolve persistent multi-account sign-in loops if clearing credentials fails.

Frequently Asked Questions

Why does OneNote keep saying 'Saved offline' even when I am connected to the internet?

This usually happens when your authentication token expires or conflicts with another signed-in Microsoft account (such as a university or work account), blocking OneNote from securely connecting to Microsoft's cloud servers.

Will I lose my notes if I sign out of OneNote to fix the sync issue?

Yes, if your notes are in the 'Saved offline' state, they have not been uploaded to the cloud. You must manually copy and paste the text into another program (like Word or Notepad) before signing out to prevent permanent data loss.

Can multiple accounts cause OneNote sign-in errors?

Yes, having multiple accounts (for example, a personal account and an educational license) signed in simultaneously can confuse Microsoft's authentication cache, leading to continuous sign-in prompts and sync failures.
