We have autodiscover working both internally and externally. But internally takes a long time to run. If I do a test of auto config from Outlook it waits a long time for https://domain.com/autodiscover/autodiscover.xml until it times out and continues to https://autodiscover.domain.com/.... There is no web server installed om the domain controllers, how can I solve the problem. Thanks Peter

Hi, have you configured internal & external URLs same as single name if yes than use different names and point your internal DNS on internal server and I hope every thing will be ok. Regards.

Hi, You may need split DNS and assure Autodiscover is resolved by internal IP address. For more information, please refer to the following article: http://www.msexchange.org/articles_tutorials/exchange-server-2010/management-administration/exchange-autodiscover-part2.html Thanks.Novak Wu-MSFT
