You don't mention Exchange server but I assume this is what you are attaching to using Outlook. Is there any NATting involved with Exchange? If so you might have an Exchange port problem.

I have a certain home user that can establish a vpn tunnel through a DSL to corporate network and all applications will work except for email. The only difference is a cisco router in between the homeuser and corporate network. Without this cisco router (with homeuser directly attached to DSL modem) there are no problems. Some one mentioned MTU could be the problem, but if the frames are larger then MTU don't they get fragmented and re-assembled at the other end. How could MTU size fail single application while everything else works fine. Thanks for any help.
