Exchange 2010 Migration Problems.
Having a problem with my exchange upgrade to 2010 fro 2003.
They have been running in coexistance for a few months now and thought the half-Term would be a great opportunity to move over all the mailboxes and decomission the old server.
I have moved all the boxes over to the 2010 server, I have created a new SMTP connector on the 2010 server, I have 3 problems.
1. When I turn off the old mail server I can send mail out but I can not recieve anymail in, ( we have a barracuda Spam and firewall 400 server, I have set the destination mail server on the barracuda to the exchange 2010 server) the mail comes into the network and shows in the message log as arrived and allowed on the barracuda. The mail however does not reach the client machine.
I switch back on the old mailserver and te mail that was waiting pings through, have I missed a step somewhere?
2. Outlook Web Apps, I have changed the external ip address to point to the new 2010 server for OWA, when you go to the page you get the certificate warning page, but when you click contnue to this website it shows a 404 error. Navigate to the internal version and it worksfine https://18.104.22.168/owa .
3. Shared calendars sow no connection when trying to view someones calendar.
I would appreciate any help on this as it's driving me nuts, thanks :)
