we have an ongoing issue with Outlook (03, 07 and 2010) losing the domain name off the end of the RPC over HTTP proxy settings for some users but not all.
(Exchange Server 2007)
so tools / accounts / connection / Exhange proxy settings.
Use this proxy server for exchange: mailserver.domain.com
Only connect to servers that have this principal name in their cert: msstd:mailserver.domain.com
This gets entered fine and works but after a reboot or even after closing and opening outlook the user loses the domain after the server and we end up with
I have tried changing the domain name to the IP address and that gets forgotten too! again this only effects some users not others and a rebuild of windows (XP & 7) / Office (03,07 & 10) doesn't fix it
I have searched high and low for a resolution to this for around 18 months now and had no joy at all
Any help that can be offered will be massivly apreciated as we're completely stuck
