I recently migrated 500+ mailboxes from exchange 2003 to exchange 2010. The problem is that the items in deleted items folder are not recycling. This is causing major issues because the mailboxes quotas are reaching limit. I have unchecked off the box "don't permanently delete items until the database has been backed up", and "keep deleted items for 14 days". I have items in my deleted items folder from February, when I moved my mailbox to exchange 2010 from 2003.
Any suggestions on what else I can do so deleted items get permanently deleted from users mailboxes after 14 days.
Thanks in advance for your help and suggestions.
