Cannot log into OneNote

It looks like OneNote is unable to authenticate your account, and the error with a Correlation ID usually means there is a problem with cached credentials or the Office sign-in token on your device. Try the steps below:

1. Restart OneNote and Sign In Again

Fully close OneNote:

• Press Ctrl + Shift + Esc

End all OneNote and Office processes Then reopen OneNote and try signing in again.

2. Clear Cached Credentials

Open Control Panel

Select Credential Manager

Open Windows Credentials

Remove any entries starting with:

MicrosoftOffice

  *OneNote*
  
     *Office16* or *Office*
     
     Restart your computer and try again.
     

3. Reset Office Sign-In Token

Press Windows + R, run this command:

%localappdata%\Microsoft\IdentityCache

Delete all files inside the folder (don’t worry—Windows will recreate them). Restart OneNote and try logging in again.

4. Check the Web Version

Go to https://www.onenote.com and see if you can sign in.

If the web version works, the issue is local to your device.

If the web version also fails, your Microsoft account might need a password reset.

5. Make Sure Date & Time Are Correct

Incorrect system time can cause token failures. Enable Set time automatically and Set time zone automatically in Windows settings.

6. Repair Office

Go to Settings > Apps > Installed Apps

Select Microsoft 365

Choose Modify > Online Repair After the repair, try logging in again.

If the issue continues, share the full timestamp from the error and whether you’re using the OneNote desktop app or the OneNote for Windows 10 app—those details help narrow down the cause.It looks like OneNote is unable to authenticate your account, and the error with a Correlation ID usually means there is a problem with cached credentials or the Office sign-in token on your device.
