Repeated Password authentication requests from Outlook Anywhere on a Server 2008 Exch2007 domain
Posted on 2009-04-29
We are having trouble with Outlook Anywhere and our new 2008 domain. We have the following setup:
DC = Windows Server 2008 SP1
Exchange Server, OS = 2008 SP1, Exchange Server 2007 SP1
The Exchange Server contains all exchange roles (apart from edge). We have mixed 2003 and 2007 Outlook clients.
We started having trouble with Outlook 2007 clients internally being asked for a password repeatedly which when entered wouldn't connect so we cancelled the box and used the TYPE password and connect option and that connected outlook temporarily.
After reading another EE arcticle we tried disabling Autodiscover's basic authentication in IIS7.0 and restarting the IIS admin service.
This seemed to fix internal clients but then Outlook Anywhere got repeated requests!!
We rolled back to basic authentication on autodiscover to try to prove a point and so far internal are still working? However Outlook Anywhere (after and initial success) is still not connecting and still exibits the repeated login boxes with no connection.
It's very strange..
We have found stuff out on the web about a bug with IPv6 but would like to post here to see if anyone can corroborate that theory.
