Hello,
i googled and googled for solution but can't find anything on this matter.
When we had Exchange 2010 with latest update (still exists during migration) and we had 3 datacenters with CAS servers all facing Internet with different name and it was silently redirecting:
europe.domain.com
america.domain.com
canada.domain.com
asia.domain.com
mail.domain.com (this one was for generic purposes and if user is in different AD site it would silently redirect to correct hostname).
Now i have Exchange 2013 with latest updates and receiving error as in picture.
When i click on link, of course it works after second authentication:
first one at generic name: mail.domain.com and second one when i go to canada.domain.com.
All external and internal host names are good. We are using split DNS so they are the same, but each datacenter has it's own name.
Hopefully someone will help with some hint because it is quite anoying.
All other stuff works good, Outlook anywhere, autodiscover, only this remained.
Thanks in advance,
Ivica
