Neil posted today about lost time due to mailbox cleanup when users hit their e-mail quotas. There are tools that administrators can use to control the size of users' mailboxes, but in Outlook 2002/2003, users have a simple entrypoint to managing the size of their mailbox from within Outlook:
1. Select the Tools menu2. Select "Mailbox Cleanup"
This dialog includes quick links to find large and old items, as well as other things such as guiding the user to empty the deleted items folder and turn on auto-archiving.
I was the tester for this feature in Outlook 2002, so if you have any problems with it, start up your time machine, go back 3 years and blame me. :-)
