So I am finishing up moving all my user mail boxes from 2013EX to 2019EX , and I noticed when I go to create a migration batch I see the follwoing error:
"The object domain.com/Microsoft Exchange System Objects/SystemMailbox{056311A3-31AB-4FD4-A6DF-8B9C45F1A639} has been corrupted or isn't compatible with Microsoft support requirements, and it's in an inconsistent state. The following validation errors happened:
Database is mandatory on UserMailbox."
Is this a system mailbox for 2013EX?
Should I be concerned?
Anyway to verify this won't adversely affect 2019EX?
Thanks, B
