Outlook XP sending problem

[Brian]

Outlook XP is loaded on a laptop and connected via
exchange and delivered to a .pst when on the network.
When traveling it is connected via dial up to a different
service provider and also delivered to the same pst file.

The problem is that when receiving an email with the dial
up connection and then going into the office and
connecting up to the exchange server you cannot reply to
the message. Now I am aware that you are receiving the
message with pop and trying to send via exchange but I
didn't think that the message could be that smart.

Is there a way to do this?

Regards

Brian

Do you get any errors when sending? What are they? Have you tried setting
the account to send from as the Exchange account (use the Accounts button on
the message)?
