Remote office - event 26 Outlook - "connection to MS Exchange Server has been lost"

I have a remote office connected over a site to site VPN over the internet.

The users there are getting the following events sporadically throughout the day:
============================================================
Event Type:      Information
Event Source:      Outlook
Event Category:      None
Event ID:      26
Date:            3/10/2008
Time:            12:15:38 PM
User:            N/A
Computer:      EID6554
Description:
Connection to the Microsoft Exchange Server has been lost. Outlook will restore the connection when possible.

Notice that they are only 1 second apart...that's how it is every time.

The Outlook interface shows the popup 'Disconnected" then "Connected".

Their internet connection shows no sign of downtime or dropped packets at the router, and the LAN is just fine as well.



Any help or advice on how to resolve would be appreciated.

Thanks Sembee...I'll do some tests to determine proper MTU size and verify.  On the TCP Chimney issue, is it similar to this http://support.microsoft.com/kb/942861 ?

If so, I can go from there...
This is the standard article I link to on the TCP Chimney issue: http://msexchangeteam.com/archive/2007/07/18/446400.aspx

Simon.
Man Sembee, I'm sorry I left this one hanging out here.

I never did figure it out yet, but the MTU sizing for their DSL connection helped alleviate the problem to few and far between so I'm letting it go until the MPLS network goes in.
