I just completed an Exchange 2003 to 2010 migration. All users are on 2010 and Exchange 2003 iswill be inline until all users are redirected to the new server. Prior to the mailbox move I was ble to send and receive both internal and external email to both 2010 and 2003 mailboxes. Now that I pointed my Symantec Messaging Gatewy to the new exchange server I can no longer receive external emails. I can still send both internal and external. I traced emails i sent and the logs state that the email was delivered to the Exchange server from Symantec.
I do not see the email in the Exchange mail queue nor has it arrive to my inbox or junk mail folder. My connectors look correct and it was receiving email prior to adding in the message gateway. Any help or ideas will be appreciated.
