I have a customer who is using Outlook 2007 tied in with out exchange server. When she works remotely through a vpn connection she hits the send button and the message disappears from her sent and outbox items however the message is never sent. She has to go to send/receive for the message to be sent. The strange part is that when expanding down the send/receive option.. the first two options "send/receive all and "this folder" do not work. But when clicking the third option "send all" the message goes through. I have tried using cached exchange mode and taking it off as well and that has made no difference. OS is XP sp3. Thanks for the help.
