Exchange 2010 fully patched on SBS 2011 Standard.
Client migrated to Office 365 and no longer needs or wants the Exchange database which is taking up a lot of disk space.
I don't need to move any mailboxes - I just want to back up Exchange (doing now with server backup) and delete the database.
I have the impression that removing the database is not possible with a simple command as it may tell me there are critical mailboxes that haven't been moved.
Is there a way to delete the database outright and free the disk space without a major operation?
I don't necessarily need to delete Exchange Server totally, though I could. I mainly want to free the disk space in the fastest way possible.
