Office 2011 14.1.3 update and Exchange 2010

[sheineken]

Hi All

I just ran the 14.1.3 update on all my Macs. We are running an Exchange 2010 server.
The problem I am having is now every time the users launch Outlook they are prompted to "Verify Certificate"

"A secure connection cannot be established with the server exchange.xxx.local. Do you want to continue"

(where xxx is my local domain)

You click continue and now outlook forcing a change to the Microsoft Exchange server field to the local exchange box. EVERY TIME. This is fine inside the office but as soon as the users leave they cant get mail.
The server should be https://exchange.xxxx.com/exchange (our public OWA address where xxxx is our company)

I go into the preferences and change it back but every time Outlook is relaunched it reverts back to the local domain.

This only started happening since I applied the 14.1.3 update.

I checked the SSL certificate in Exchange and it is fine. Nothing has changed.

Any suggestions??

Thanks
Jeff
