Outlook 2003 clients going offline

We currently are running an Exchange 2003 cluster, clients are running Office 2003 in cached exchange mode.

We have been experiencing an issue where some client's Outlook will go to the Offline state, thus no longer sending or receiving email until they uncheck the Work Offline in the lower right hand corner.  

Some are users at remote sites, some are local to the server.  Does not seem to depend on the setup type(upgrade or clean install), OS(XP or 2000).  For instance, it happened to a brand new PC setup the day after it was installed.

The Exchange server is up the entire time and there are no issues with that as far as I can tell.  The Outlook client is open when this happens, may happen in the middle of the day or overnight.

Any ideas will be appreciated.

rcmb,

I do have my users set to "Manually control connection state"

Can you explain why I should change it to "Automatically detect connection state?"

joewvogel - sorry to jump in on your post like this.

We are currently set to Automatically detect.
Automatically detect allows outlook to determine on its own what your conntection status is so it can queue your outgoing mail or not automatically get mail, etc.

I recognize that this is not always the best way to do this, I was troubleshooting the problem joewvogel is having and it may have been related to the connection state issue. If outlook is unable to determine what the connection status its it may go offline.

I thought that when it is in Automatic, which we do have it set to, it will go to disconnected state, not offline.  Is that a correct assumption?

No, we are using MAPI.
I run a network of approximatly 2500 users. I have seen both cases in different versions of outlook. In some of my remote buildings where I only have low bandwidth I have seen the direct connection go to offline vice disconnected. No sure why that happens butit does. We run a mix of outlook clients (2000, 2002 and a few 2003). Mostly I see this problem with OL2000 but I was trying different solutions to see if we can isolate your problem.

I run all of my users in Automatically connect and in the areas where I can provide excellent bandwidth (100MB) I never see the problem.

I have done some extensive research on this issue and cannot seem to find a good permanent solution other than mostly it deals with bandwidth.

Sorry I cannot provide more.

i've had a similar problem with outlook 2003 [no other version gives me problems]:
for some reason, when on a local 1gig ethernet connection, outlook goes offline immediately after doing a send / receive.  it sends and receives ever minute [per the settings], but immediately goes offline after.  he still gets his mail, but makes using the public folders impossible.

solution was simply to go in and take off the exchange cached mode, get out of outlook, then go back in and turn it back on.
make sure you don't have both cache mode and offline folders enabled, use either one or the other.
