I've only ever seen this myself in three cases from cached mode OL2k3, 2k7, and 2k10 against Ex2k3:
1.) [Over a VPN] While the client is catching up 2.) [On the LAN] Briefly, after rebooting Exchange and everyone is re-attaching 3.) [On the LAN] Migrating a user from PST storage to Mailbox on the server while OL is creating the OST. This points to two root causes: 1.) Network connection with high latency and low bandwidth 2.) Overloaded Exchange server (Disk I/O request latency) Yea, our server is sucking wind. I can only assume that non-cached mode would worsen those situations.
