Outlook Anywhere or RPC over HTTP

I have been looking at this for I don't know how long now but I can't get outlook anywhere to connect.  Outlook acts like its going to connect asking for the user name and password but just asks a few times and gives the error:

"The connection to microsoft exchange is unavailable.  Outlook must be online or connected to complete this action"

I have never set this up before so I'm probobly missing something. But here is what I have setup

-SSL Cert from Network solutions I can get to remote.domain.com/owa with no cert error.
-In outlook I have "Connect to Microsoft Exchange using HTTP" set with remote.domain.com, connect using SLL only, connect to proxy server that have this principal name in their certificate msstd:remote.domain.com, and Basic authentication.
- Outlook Anywhere is enabled with external host name remote.domain.com and authentication set to Basic
- I have tested the username and password on OWA just fine with no problems.

I'm using Exchange 2007, IIS 7, on SBS 2008 and Outlook 2007

Try the Microsoft Exchange test and select the rpc option to see if it reports any issues:

I ran the test above much to my suprise everything passed.  So i setup and Outlook profile with all the info and it worked fine.  Last thing i did was installed the SSL Cert on the server and restarted the site.  It was not working after I did that.  I tried it again one more time since i left work and it still was not working.  Havn't done anything the past few hours and now it works??  Is there some sorta automatic update or something else i should of restarted?

you shouldn't need to restart anything after installing a certificate

Agreed, it will not work until the certificate is installed but that takes effect immediately. There are some changes that require restarting Exchange routine or wait 90 minutes but none that I am aware of that would be affected by enabling rpc/http

Firstly make sure that your outlook is configured correctly and working via the normal transport mechanisms.

Run "Outlook /rpc" and it should show you what protocols Outlook is trying to use to connect to the server.
