SYMPTOMS

A Macintosh attachment in a message comes across as an unrecognizable document after crossing the Internet Mail Connector (IMC). The message is sent from a computer running Microsoft Exchange Macintosh client 4.0 Service Pack 3 (SP3) to a computer running Microsoft Exchange Macintosh client 5.0. Both IMCs are configured to send attachments in Binhex, always sending rich text.

CAUSE

Macintosh attachments sent from Microsoft Exchange Server 4.0 SP3 to Microsoft Exchange Server 5.0 in Binhex+TNEF are not received properly (wrong icon, unrecognizable file type, and so on). This is because of the incompatible Macintosh file handlings for UUENCODE/TNEF between 4.0 SP1 and 5.0.
