Exchange 2010 Autodiscover Settings

Hello,

I am so close to tweaking out this new server but I have an annoyance that I cant seem to fix and do not want to turn things upside down getting it removed. Basically, I don't use auto discover to configure my external mail clients, I do it manually. We have a .us domain but the auto discover changes my settings to .com in the proxy settings which then the user cannot login. I assume this is because when I built the server, I set it up primarily with a .com as we already had .us on another production server.

I guess I would use auto discover if it used the proper information, so how do I edit it, or where do I go. Seems like  simple enough thing to do but you think I would have ended the end users lives with the last migration so I am trying to do it without making any ripples. Mostly users are not having issue except one users client will not stay on .us, it flips back every time he opens Outlook 2007

Any guides or resources would be appreciated, but before I learn all about autodiscover, i would probably be curious how to alter the certificate or whatever is prompting the change to use the proper domain.

THANKS!

If you use a 3rd party certificate for autodiscovery to point to your .com then anyone connecting to outlook will use the cert and can send receive mails.

Ok, thanks for the prompt reply. I am not able to test until now.

Here is what I did using the advice above.

get-outlookanywhere which would then show my external hostname was domain.com
set-outlookanywhere -externalhost domain.us

then it prompted me for identity, which had to add the full name listed in the get info as I was typing it wrong.

So I gather from reading about these changes I need an IIS restart, so I will do that and see how she does in the morning. If I dont have any issues I will post back and close up the question.
