Failed Exchange Database Content Indexes (Dag Member)
Hi,
I am getting "Failed Exchange Database Content Indexes" for a database added in Exchange 2013 DAG. The database is added only to one of the DAG members. The database is dismounted. If I try to mount, it shows the below error:
Failed to mount database dbname.edb". Error: An Active Manager operation failed. Error: The database action failed. Error: Operation failed with message: MapiExceptionDatabaseError: Unable to mount database.

"Update-MailboxDatabaseCopy dbname\exch02 -CatalogOnly -BeginSeed"
but it says
"The operation couldn't be performed because object 'dbname\exch02' couldn't be found on
'dc01.domain.com'."There is only one copy of this database that exists on exch02.
