We have Mailbox server which is part of Ex 2010 - DAG. We have database named :Mailbox Database 1803077165 on this server.
The size of this database 4.5 GB resulting in low disk space on the drive.
The database is present in the Exchange server folder : C:\Program Files\Microsoft\Exchange Server\V14\Mailbox.
We have moved some the mailboxes from this database however size is not reducing.
We also have system created mailbox on same mailbox database. Admins moved some user mailboxes to this database unknowingly.
I am mlooking for option where in we can reduce the size of the database without taking downtime.
We had moved user mailboxes but the size is not reducing.
