3 Ways to Fix Unable to Sign in to Microsoft OneNote on Windows

Fix 1: Remove OneNote Credentials From Credential Manager

The Credential Manager in Windows stores login details for all your apps. If you recently updated your Microsoft account password or Credential Manager data has become inaccessible, OneNote might keep showing the “Sign In Required” message.

To fix this, remove your OneNote login details from the Credential Manager by following the steps below.

Step 1: Press the Windows key + R to open the Run dialog box. Type control /name Microsoft.CredentialManager and press Enter.

Step 2: Select Windows Credentials and locate Microsoft OneNote on the list. Then, click Remove.

Log into the OneNote app again and check if the issue is still there.

Fix 2: Clear OneNote Cache

Microsoft OneNote stores certain information locally on your computer to load quickly and serve you better. If this data becomes corrupt, OneNote may have trouble signing you in. Thankfully, it’s easy and safe to remove these cache files.

Step 1: Press the Windows key + R to open the Run dialog box. In the text field, type the following path and press Enter.

%localappdata%\Microsoft\OneNote\16.0\cache

Step 2: In the File Explorer window that opens, select all the files and click the trash icon at the top to delete them.

Fix 3: Repair or Reset the OneNote App

If you still can’t sign into OneNote, use the built-in app repair feature on Windows to fix the app. Here’s how.

Step 1: Press the Windows key + S to open the search menu, type OneNote in the search box, and select App settings.

Step 2: Click the Repair button. When the process is completed, a checkmark will appear next to it.

If you can’t sign into OneNote even after this, try resetting the app from the same menu. Afterward, head over to the Microsoft Store to update the OneNote app and sign into your account again.
