Hi all, I'm in panic mode. My mailbox store shot up from 10Gb to the max 16.7Gb in a few weeks (probably BackupExec was the culprit, not sure though). I'm deleting old mailboxes and have also instructed the users to delete any unnecessary e-mails, but the mailbox store is not reducing in size. How can I reduce it? I noticed the message retention setting was set to 30 days, now I have reduced it to 0, am I correct in thinking that this will flush any tombstoned items? If not, how do I clean the deleted stuff? HELP! Normally-chilled-and-helpfully yours... Andy
