Poor performance using Outlook 2003 Cached Mode with Exchange 5.5

    We are experiencing poor performance when using Outlook 2003 in cached mode (Exchange 5.5).  In general, the symptoms are extreme delays in performing synchronizatons, and incomplete synchronizatons.  After a lengthy synchronizaton (several minutes with a high speed connection, and 30 minutes or more from a dial-up), we notice that even though the message "All folders synchronized" shows up, often times, the more recent Inbox items have not been synchronized.  We see these symptoms even when the amount of update is fairly small.
     We have tried several different send/receive group settings.  We have a set for
1.   "Traveling Offline Mode" with just the Inbox, Sent Items, Calandar, Contacts, and Outbox included in the Send/Receive group.  Only the "Include this group in send/receive" when Outlook is Offliine  box is checked.  This setting is intended for use by travelers using a dial-up connection
2.   "Traveling Online Mode" with just the Inbox, Sent Items, Calandar, Contacts, and Outbox included in the Send/Receive group.  Only the "Include this group in send/receive" when Outlook is Online box is checked.  This setting is intended for use by travelers using a high-speed connection.
3.   "Offline Mode" have all of their folders included in the Send/Receive group.  Only the "Schedule an automatic...", and "Perfrom an automatic..." when Outlook is Offline  box is checked.  This setting is intended for users in offices without Exchange servers that are operating offline (through a T1 WAN connection with their Exchange Server)
4.   "Online Mode" does not have any folders included in the Send/Receive group because all folders are automatically being synchronized in Cached mode.  Only the "Schedule an automatic...", and "Perfrom an automatic..." when Outlook is Online  box is checked.  This setting is intended for users in offices with or without Exchange servers that are operating online (through a T1 WAN connection with their Exchange Server)

Any suggestions??

Using Catch mode with Outlook 2003 make you need just one profile.
DON'T set it to replicate anything!! And never use F9!
If you do it only interfere with the catch mode since they fight the resources.

While the Catch is trying to intelligently download what it need the replication (or F9) want to download everything disregarding the band wide setting

You can use Shift F9 if you are having good line and you want to download the current folder.


Let it work
And of course if you can move to Exchange 2003 ;)

What about when working offline?  It seems that only folders that are selected for send\receive (F9) replication get updated.  Does "intelegent" downloading work the same with Exchange 5.5 as it does with Exchange 2003.  I know that the header type options are not available, but is bandwidth integrety taken into account with Exchange 5.5 or does that also require Exchange 2003.

Hopefully, we will be migrated to Exchange 2003 within the next 6 months.

You are not suppose to work offline
Catch mode detect it by itself and set it to Disconnect mode. (Same as it detect the Line quality and decide weather to bring just headers or full body (use the defaults)

The "Intelegent" download works better with Exchange 2003 just becuase Exchange 2003 is designed for it.
But it will work without it as well.
