I rescentley had a call from a customer that said there messages didn't show up till the next day on a cadence. This doesn't happen all of the time, only once or twice every two weeks. I can't duplicate the problem but the customer is very upset. I have deleted the mailbox and rebuilt it. So far this is happening on two extensions. Any ideas on what could be causing this ?

Tough one,a technicians nightmare when it only occurs that often.I honestly don't know where to start troubleshooting this one.Have you tried tech support at all?

Afterhour messages? Personal mailboxes?

It happens during the business day on two personal mailboxes. Tech support had me delete the mailboxes and recreate them however I am still having the problem. Just curious if anybody else had run into this type of problem.

Could a message from another mailbox be forwarded to the two problem mailboxes? I would check all mailbox programming? Seems like I recall having a similar issue.
