I have a Windows server 2008 SBS with Exchange 2007 I can open Outlook and see my email, I can send email but all of a sudden incoming email is not working. I can ping my mx record mail.company.com and IP is correct, I have a broadband provider and the ports are open, exchange is up to date, windows server is up to date, no errors.I restarted the server, the cable modems, I checked my antispam and is working fine. I raised the database size limit in the registry. I am at a lose of words, I have no clue what is going. I have never seen this before. Nothing is sitting in the queue either.
