Users migrated from Exchange 2007 datastore to 2010 datastore do not receive external email
Posted on 2014-11-06
We have a single Exchange 2007 server that runs our company email. I have deployed a new Exchange 2010 server, and the plan is to migrate all of the users to the 2010 server. I migrated one user from 2007 to 2010 for testing purposes. This 2010 test user:
- can receive internal email from people on the Exchange 2007 server - OK
- can send email to people on the Exchange 2007 server - OK
- can send email to people outside of our organization - OK
- BUT they do not receive any outside email
We have a Barracuda spam filter that receives all messages first. It blocks some and lets the others through. For this test user, the Barracuda filter IS receiving the messages and stating that they HAVE been delivered. However they never show up in the test user's inbox. I have no idea where they are going.
We also have Choicemail installed on both Exchange servers. The configuration from the 2007 server was duplicated on the 2010 server. Choicemail is configured to filter messages for only one specific user though, which is NOT the test user.
Thank you for your help!
