Exchange 2013 Server Migration

Hello,

We are in the process of migrating from an Exchange 2003 server to an Exchange 2013 SP1 server. The EXCH2003 server is in a separate domain environment than the new EXCH2013 server. We plan to export all mail from the EXCH2003 server and import to the EXCH2013 server.

At this time we are seeing an issue with the new EXCH2013 SP1 server. When we test creating a new profile in Outlook 2010 SP2 on a client machine we receive the following errors:

1) The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.

- also -

2) The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.

We are able to access OWA both internally and externally and can login under multiple user accounts. Also while logged into OWA, mail flow is working, able to send and receive.

We installed and configured a new SSL trusted certificate on the Exchange 2013 SP1 server as well.

At this time our main issue is with Outlook 2010 SP2 and Exchange 2013 SP1 not communicating with each other properly.

Please let us know what other information is needed to help resolve this issue.

Thank you,

Jason Ri

Hi

Do you have autodiscover records setup for the new EX2013 server?

Hi,

Thanks for the reply on this topic.

Yes, I do have autodiscover records setup for the new EXCH2013 server.

We can get to a point where Outlook 2010 SP2 will see the user account and pull the email address for the user, but then it prompts us for the user credentials and seems to hang at this point with the error that Outlook needs to be connected to an Exchange server or online to complete the action.

As commented by ED please make sure autodiscover is pointed to exchange2013. 

Please try to restart the services, restart  "MS exchange active directory topology services" It will restart the dependent services. Please restart "Microsoft Exchange System Attendant" service also and try

After this try creating a test mailbox in exchange2013 and try to configure the newly created mailbox in outlook2010.

Test OutlookAnywhere using https://www.testexchangeconnectivity.com/ and check for any error.

Make sure you can ping exchange2013 server by it's name(Netbiosname and FQDN)
