Gmail and GDrive backup fails with error EUSERNOTFOUND
Updated over a week ago

Problem Statement:

Gmail and GDrive is not backing up with error message ‘EUSERNOTFOUND’


The ‘Cloud App Settings’ is set to use UPN.

Google Workspace does not support UPN and works on email id.


  1. Go to the Google Workspace Overview Page

  2. Click on the 3 dots on the right corner>Settings

  3. Change the 'Cloud App Settings' to 'inSync Email ID'.
