the server has windows sbs2003 installed, and is using ISA.

We have a single user who has problems when replying to emails connected via the OWA.

They receive the following error:

the page cannot be displayed......."      Error Code: 500 Internal Server Error. The request was rejected by the HTTP filter. Contact your ISA Server administrator. (12217)

Having researched this error I have found one known issue in the microsoft KB which does not apply.
KB837865 - this article refers to high bit characters being blocked I have checked and this is not the case with our Server.

I should note that the other user who uses OWA does not receive this error, but they have windows vista installed on their laptop as oppossed to XP.

when tested from an internal location with windows xp the error does not occur.
