Okay, you've clarified that for me. I understand that rescan isn't a nightly task, but could be run every now and then periodically. How often might be appropriate if I wanted to do this as a maintenance task? Once a month? Lastly, I'm trying to use the index command instead of the search command, but I can't figure out how to make it index every mailbox for every user. Is there a wildcard that can be used for the mailbox? Or do I need to iterate all the mailboxes with one command and run index however many times for each inbox? Thanks for your help
