>> Hi All,
>>
>> Hoping someone can help me with this issue that has just surfaced at a
>> customers who have recently upgraded their server.
>>
>> Our application sends faxes using simple MAPI/Outlook using simple MAPI
>> api by emailing to a fax recipient whose address is in the format
>> [Fax:XXXXXXXX]
>>
>> This was working fine through Win2KSR3/Outlook 2000 SR1 with the fax
>> transport routing the faxes through a local fax modem.
>>
>> We have since updated the system to XP SR2/Outlook 2003 and are routing
>> the fax transport through the shared fax on an SBS.
>>
>> Sending directly from outlook works fine as I believe its not relying on
>> the MAPI api, but using its internals or CDO.
>>
>> But sending the fax message through MAPI result in the fax not being sent
>> and the following message returned to Outlook:
>>
>> Your message did not reach some or all of the intended recipients.
>>
>> Subject: E-MAIL FROM XXXXXXXX
>> Sent: 10/25/2008 10:21
>>
>> The following recipient(s) could not be reached:
>>
>> '0XXXXXXXXXXXX' on 10/25/2008 10:21
>> The message could not be delivered because the recipient's
>> destination email system is unknown or invalid. Please check the address
>> and try again, or contact your system administrator to verify
>> connectivity to the email system of the recipient.
>>
>> <sbs.domain #5.1.2>
>>
>>
>> If anyone can shed any light on this problem it would be very much
>> appreciate as its had me stumped for a few days now and I don't seem to
>> be getting anyway, hopefully its just a setting that needs to be changed
>> on the server.
>>
>>
>> Thanks,
>>
