An Exchange 2010 server is in place, I installed a 2013 server and prepping for migration. When I try to move Exchange 2010 user mailboxes to Exchange 2013 database, I get the following error message:
Cannot open mailbox /o=COMPANY/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=SERVERNAME/cn=Microsoft System Attendant.
When I open cn=Microsoft System Attendant, the container is empty.
I tried a number of suggested fixes from the hyperlink in the error message but none worked.
