Strange Exchange 2003 / Outlook 2003 Connectvity Issue

Dear All,

I have joined this website today, great source of information and read dozens of questions  & answers.
Unfortunately I couldn't find anything which helped me.

I am having issues since this morning, with Outlook 2003 which cannot connect to our Exchange 2003 (SP2) Standard server. Exchange is installed on a Windows 2003 Standard server (SP1).
Some users, our Citrix users can connect with the Exchange server. OWA works as well.
Also RPC over HTTPS, BUT NOT THE REGULAR EXCHANGE connection from our branch locations (10 locations; VPN network).

We (my colleague) did yesterday some DST  and security updates on the Exchane and fixed some database problems with eseutil.

Our Exchange resides in the 192.168.1.x network.
In this network segment are the DC's and the GC server, also our Citrix Metaframx XP servers with Office (Outlook) Outlook 2003 installed are in this network segment, which is our datacenter.

We have 10 office locations with a local DC which are connected to the datacenter servers over a Cisco VPN network.
All the users in the office branches, who use Citrix (datacenter) over their thinclients can open their Outlook and get a connection. All people who are in the branches who work from PC's/Laptops and have a a local MS Outlook 2003 installed can't connect since this morning, except of those who have their Outlook over RPC over HTTPS configured.
At the moment I advised the people to connect over OWA, which is a poor solution.

I am sitting in one of the branch locations.
When I VPN into the datacenter onto the CISCO VPN concentrator my Outlook can connect just fine, when I try to go over the static VPN connection in the office I just won't connect.

I can ping the Exchange server and DNS looks fine. Also when delete the Outlook profile and set it up again, it underlines me the mail server name and the username, which shows me, that Outlook connects and resolves names.
But then I just won't send & receive emails.

I tried to telnet to the exchange server over the port 135 which works over VPN client connection but not over the static VPN network in the office. Is that a sign?

Please advise urgently, I am desperate.

Thank you so much.

Alex
