Environment:  Windows Server 2003 & Exchange Server 2003 SP1 servers; Windows XP SP2 & Outlook 2003 clients.

I have 2 users out of a possible 80 who constantly complains there loose connection to the exchange server, they will be working in outlook/calender and will get a message ""lost connection to exchange server "  After a minute or two, everything goes back to working just fine, this can happen 2-3 times a day, Are you able to give me some advise as to what I can check on thier local machines before getting our Network Engineers to investigate traffic on the switches in the office.

as mentioned, this only seems to effect 2 out of a possible 80 staff,
your point noted, that's in our future plans.

First try to figure out that, only the outlook get disconnecting or their pcs get disconnecting from network?

specifically thier outlook,
they not running outlook in cached mode, do you think turning this on will make a difference?

I don't think that it will affect to the connection disconnection.

Turning on cached mode may not affect to the Exchange disconnections, however it may enable your users using Outlook without interruptions (because it's cached).
Also, have you maybe installed Outlook (Office) 2003 Service Pack 3?

Have you checked the power saving options on the clients PC:s? Take a closer look at the power saving option on the clients network card, that could lead to this kind of problems...

Network Connections -> Local Area Connection -> Properties -> Configure -> Power Management
Uncheck "Allow the computer to turn off this device to save power".
