I have some users who gets a login box for Outlook 2007.
The login prompt box says "Welcome back to mail.domain.dk". I have a SBS 2008 and the problem is that i have a UCC installed and i have created a autodiscover.domain.dk A record in the DNS
The most wierd thing is that the Autodicover works sometimes only?!?!. Test the autodiscover settings from https://www.testexchangeconnectivity.com/
i get a success message.
However after a while(30 min. after) i test the autodiscover service through https://www.testexchangeconnectivity.com/
again and it fails. Then i have to make some changes on the IIS before the Autodiscover comes up again.
The changes i make is that under the Autodiscover site -> SSL Settings i uncheck the " Require 128 Bit" checkbox. When the Autodiscover fails again i check it back to "Require 128 Bit. " I have to switch between these two settings..
I don't know what it could be..
