Outlook 2007 loosing connectivity to Exchange 2003

[Zoran]

Hi all!

We have an Exchange server 2003 and Outlook 2003 and 2007 clients connecting
to it.

Most of our users are having laptops, and when then undock them, their LAN
connection is closed, and WLAN takes over. This setup is working fine on Win
XP + Office 2003.

But those users having Office 2007 installed (on both Vista and XP) are
experiencing that often Outlook looses connection, goes Offline having no
connection to the Exchange server! Usually it helps to restart the machine,
but sometimes not even that! We've tried a lot of things, repairing the
profile, deleting the profile and creating a new one... But did not come to
a final solution, the users are still having the problem...

We are having 2 DC's, 2 DNS and 2 WINS servers, and clients get their IP
from the DHCP server - but I don't think that it is a connection problem,
since Outlook 2003 clients can connect.

Suggestions?

Thanx in advance,

Zoran

Have your users uncheck the "Cache Shared Folders" option ( I assume
they are in cache mode) and see if that makes it better.
Outlook 2007 and Exchange 2003 is not always better together.
