I have recently installed a new Exchange 2007 server onto an existing domain with Exchange 2003. The installation passed with no errors and I had set the existing Exchange 2003 server as a bridgehead on the 'Mail Flow' setting. A connector is visible in the old exchange System Manager between the old and new servers. I migrated a test account from the old 2003 server to the 2007 one. The account logs in to both Outlook and OWA with no problems and can also send emails to internal and external addresses. However, the account is not recieving any emails. Sending to this account returns no error messages and delivery reciepts provide no feedback. I am sure that this is just a setting somewhere that is incorrect, can anyone give any pointers?
