Hi Everyone,

I have two questions about exchange server migration. When I migrate a mailbox from exchange 2010 to 2013 server, I get an error in the outlook client saying that the administrator has made a change and outlook needs to be restarted(no big deal, I can live with that).

When outlook is restarted it fails to connect to the new exchange server. The fix is quite easy, I open up the account settings and hit repair:

What I notice after this(outlook is restarted and it connects successfully) is that the mail server ID has changed to a random string rather than "exchange.domain.com"

So two questions:

1. Why is my mail server ID like that. Have I setup something wrong in AD?(the old mail server has it's DNS name)
2. Is there a way to make it so outlook doesn't have to be "repaired"

Other than this, everything appears to be working fine. Users still on exchange 2010 can email 2013 users and vice versa.

I am running Exchange 2010 SP3, and Exchange 2013 CU6. Outlook 2013 client is version: 15.0.4569.1506

Thanks!

Hello

1 its normal it ExchangeGUID  Get-mailbox username | ft name,ExchangeGUID
2 check autodiscovery url, and check exchange setting with Microsoft Connectivity Analyzer Tool

Thank you, the GUID makes sense now

I have my autodiscover URL (DNS entry) pointing to my 2013 CAS server. I'm not sure what else is required? I'll try the analyzer tool and get back to you(providing I can get it into my offline/isolated network)

Hi,

From your description, I recommend you to update your Outlook 2013 to version 15.0.4569.1508. It should resolve the "The Microsoft Exchange Administrator has made a change that requires you quit and restart Outlook." problem.

For your reference:

Outlook 2013 cannot connect after an Exchange Server 2010 mailbox is moved to Exchange Server 2013

Hope this can be helpful to you.

Best regards,

Thank you, I'll run through some windows updates and see what happens
