In our SBS 2003 environment, we have Windows XP SP2 workstations that are
using the fax mail transport in Outlook 2003 SP1.

All but one workstation can send word documents in Outlook via the fax mail
transport.

The error message reads:

'The Microsoft Fax transport failed to deliver the message to the
recipient.
Not all attachments can be rendered.'

I have tried to uninstall the fax mail transport and reinstall it, but it
didn't fix the issue.
