I have an Exchange server with some issues, which I think they are related.
The Exchange server used to be hosted by a trusted domain in a different site, we recently moved it over to the local LAN, and it is now part of the same domain and site as the rest of the network.
The issues we are having are as follows:
1. Autodiscover configures Outlook using 'HTTP Proxy'. Any attempt to change that so that Outlook should connect to the Exchange server using the local DNS name, reverts itself back when Outlook is restarted.
2. The GAL does not update on the client Outlook. Forcing an update does not help.
3. Occasionally, 'some' users keep on getting popups to enter an Exchange password..
Please advise how to fix auto-discover first.
