I am having problems when trying to restore a mailbox.
I get an error:
Cannot open mailbox /o=First Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=MBXsvr/cn=Microsoft System Attendant
This is the first time I have tried restoring mailbox on this 2013 Server. This 2013 server is from a recent 2010 migration.
I also recently lost Discovery Search mailbox and had to recreate it.
I found an article on 2010 that says to set the homeMDB, but I am not sure if that is needed in 2013. There is none set in this AD.
