Hello,Recently we reinstalled exchange server. We had problems configuring it to allow mail to pass through but this has now been resolved.Email was offline for 2 days.Day 1, email was able to send (using a separate SMTP), but not to be received.Day 2, email was able to send and receive, but all emails from day 1 did not come through.Is there a way to force this mail to be delivered? It is still showing up in the Mail Box Store. I am curious if the mail was incomming, but never delivered if it is possible to force delivery.EDIT - It seems email is slowly coming through from the previous days. Strange problem this is. I've just received several emails from the last few days over a period of 3 hours. Perhaps I should just sit and wait.

Wait it out. The domains of the senders have queued up your messages and will retry on predefined intervals. Test from outside mailboxes and ensure new test messages come in fine. regards, Jeremy
