In the process of migrating from Exchange 2007 to Exchange 2013 for a private school.
I've set up Ex2k13, migrated a former employees mailbox to 2013, and OWA/mail flow working fine.
Original AD domain is: old-school.org
(this would be domain.local in generic examples)
Current email domain we are using is: newschool.org
Existing 2007 Exchange server name: emailserver
New 2013 Exchange server name: EX01
But Outlook 2010 for the migrated user:
When Outlook is started, I get the username/password box.
Note - the title of the box shows the old server name:
Connecting to: emailserver.newschool.org
Username and password rejected, but as I keep entering it, a Security Alert pops up:
<check> The security cert. is from a trusted cert. authority.
<check> The security cert. date is valid.
<red X> The name on the security cert. is invalid or does not match the name of the site.
When I view certificate details:
Subject Alternative Name:
DNS name = owa.newschool.org
DNS name = www.owa.newschool.org
DNS name = autodiscover.newschool.org
DNS name = EX01.newschool.org
It seems to me a start is to get the EX01.old-school.org
to be seen as EX01.newschool.org
So how to do this?
Once that is done, I guess updating autodiscover internally to point to the news server is in order (after I've moved mailboxes.)
