I am administering an Exchange 2007 server with around 15user mailboxes. One user is having trouble receiving emails from an email address outside the organisation.
I've run the message tracking tool with EVENTID as 'Receive' and can see this particular sender email address in the results.
If i run the same tracking search with EVENTID as 'DELIVER' - The emails do not show up.Therefore I can see the email is getting to the exchange server, but NOT delivering to the mailbox.
I've heard I should disable IPV6 if its not in use as this can cause problems, is there any truth to that?
