Try disabling Exchange cache mode.

Remember that you are using the network connection to the remote desktop
which is the same network connection used to connect to the Exchange
server. Could be you are simply flooding your NIC with so much traffic
that delays are incurred for Outlook on the remote host trying to get at
the Exchange server.

I don't know how well RDP handles graphical data, like your desktop. If
it attempts to transmit the entire screen to reflect a single pixel
change, that's a hell of a lot of traffic. I know that some versions of
VNC will only send incremental screen changes to reduce traffic size.
You might want to try TightVNC instead of RDP.

I agree with your theory, given that this seldom happens when I'm not using
RDP. I already have Exchange cache mode tuned off. Any other suggestions?

Thanks

If you are allowed by your company to connect to your workstation using
RDP then they should also allow you to use VNC. See if the same problem
occurs when using TightVNC.
