Research this issue for 4 days and I'm still not sure how to fix it. I have two exchange 2010 servers in my environment and I recently deploy new exchange 2013 server. I moved my inbox to the new server and everything is working fine. I'm able to send and receive emails internally and externally as well as accessing OWA. But on my android phone I'm getting error "failed to connect to exchange server".
Some points to consider
- I was able to receive emails on my cell when my mailbox was in exchange 2010.
- From Exchange 2013 I'm able to see the two Exchange 2010. I'm not able to see Exchange 2013 db from Exchange 2010.
- In exchange 2013 I configured receive and send connectors to 2010 and external URL
-All our inbound and outbound email traffic are going first thru McAfee email gateway and than forward to one of the exchange 2010. Auto discovery point to 2010 server.
- Exchange 2013 use the default certificates
Thanks in advance
