Issue: I make a domain account on my pdc. I goto make a mailbox on my exchange server and it seems that the account is not being populated in the domain because i can't link the mailbox to the domain account. It seems to not exist. I go back to my pdc and there it is. First trying to find out what can fix this (already rebooted). Second trying to find out where the issue lies, my pdc or the exchange server. Appreciate the support!
