Hi there,
I did a migration in a single domain with 100 users from 2 CAS (NLB) + 2 MBX (CCR-Cluster) 2007 to 2013 mostly according to this tutorial:
http://www.msexchange.org/articles-tutorials/exchange-server-2013/migration-deployment/planning-and-migrating-small-organization-exchange-2007-2013-part1.html
It all went quite well and the environment is in production for 2 weeks now, I´m a little bit confused about Outlook (PC) is talking about a bad Certificate on the proxy (mail.mydomain.de, which is a good one!) with error code "0", but OK, I though as soon I can switch Echange 2007 off this will be gone.
BUT:
As soon as I switch off the old infrastructure then strange things happen:
Outlook-PC: Users will repeatedly asked for their credentials
Outlook-Mac: Everything is working
Outlook-iOS: Everything keeps working
OWA-APP iOS: stopped connecting at all
OWA on any Desktop: Everything is fine
Apple Mail on iOS: stopped connecting at all
I switched the SCP for 2013 Server:
"Set-ClientAccessServer -Identity Exchange2013 -AutoDiscoverServiceInternalURI https://autodiscover.mydomain.de/Autodiscover/Autodiscover.xml"
I marked the old SCP-entries from the Exchange 2007 CAS hidden for everyone in AD
I set OWA to point to the Exchange 2013:
Set-OutlookAnywhere -Identity "exchange2007\RPC (Default Web Site)" -internalHostname mail.mydomain.de -internalClientsRequireSsl $true -DefaultAuthenticationMethod ntlm
The Autodiscover-Tests Outlook processes on client side ist completely successful.
Any ideas what is missing?
Thank you.
