Steps to Reproduce

The error shows up sporadically.

Root Cause

User connects to a Google mail mailbox account, the error message is specific to Google.

No documentation is available that explains the exact reason for that message, but it is clearly a problem on the server side. 


Repeat getting the email or use another email provider.
