I need to delete some user mailboxes from exchange 2013 database to release the storage. Each of those mailbox has 40-50G of data. Those mail boxes have been exported as backups. There is a retention period of 14 days by default that all deleted items will still be hold in database. The situation is that I need space right now and I want to bypass this retention period and have those mailboxes removed from the hard drive imminently.
Is there a way to do this? I could not find the solution online....
Note: They are disconnected mailboxes, User accounts will still be in AD.
