unable to connect outlook 2007 to exchange 2007

Yesterday our exchange server tried to install exchange 2007 service pack 1 rollup 7 and failed miserably.  It hung on install and we were forced to remove it.  We have left it removed and have been troubleshooting the resulting errors today.  

So far to get exchange back online I had to delete and re-create the OWA virtual directory, that brought webmail back online.  Then phones would not reconnect, so I had to delete and re-create the activesync virtual directory.  That brought some phones back online but I ended up having to replace the EWS virtual directory to get our BIS blackberry users to come back online.  However once I did that I recieved a phone call from a user who's outlook and OWA stopped working.

I got his OWA working for now, but now my server is reporting a cert mismatch between what it has and how people are connecting to it.  

We have it setup for plain text password exchange.  OWA and RPC over HTTPS was working fine before the EWS reinstall, is there some settings I messed up by reinstalling the EWS directory that i need to reset now?  Currently users who are logged in and do not log out do not experience any problems but this is going to soon come to a head.

I was doing some other research and could not fund the RPC over https proxy service on my exchange server, all I have is the RPC over http service called RPC/HTTP Load Balancing service.  Shold I uninstall RPC over http and reinstall it?  if so are there other settings that I will need to reconfigure after the reinstall?  Thanks

After further review and a call to our local tech shop for some exchange 2007 help, we came up with the following solution for our RPC issue.

Apparently with rollup 7 if it installs half way and you back it out, it leaves some kind of marks on some of your services, in our case it upgraded EWS and activesync but did not update OWA, RPC or any of the other directories.  Even after the install the folders were unrecoverable and the version mismatches caused communication problems between RPC and the rest of the server.

Our solution was to properly re-install all updates for our server that we had in the que.  This included multiple security patches and rollup 7.  To install Rollup 7 we downloaded the file straight from Microsoft and were able to install it properly, without a hang, not to mention we took the steps to disable all services that accessed the databases, including AV and spam filters.  So after rollup 7 installed, OWA was still not responsive so I ran the following commands to recreate the owa virtual directories, through the exchange command shell

1. Type Get-OwaVirtualDirectory. this gave me a list of the virtual websites currently in our directory, the one I wanted to replace was OWA, soooo
2. Type Remove-OwaVirtualDirectory -identity owa (Default Web Site)  this deleted
3. Type New-OwaVirtualDirectory -OwaVersion Exchange20073 -Name owa (Default Web Site). This will create the Virtual Directory again.

This restored our OWA and RPC to full working order.  However it did create a seperate problem with our exchange cert.  Internal users are getting the following error located in a popup.  "The name on the Security Certificate is invalid or does not match the name of the site."

After a little research I found the following fix and am waiting to apply it until I can run it past my boss and a few more people.
