SYMPTOMS
Macintosh clients who use a MAPI connection to their Exchange 2000 computer cannot connect when the Exchange 2000 computer is protected with Internet Security and Acceleration (ISA) Server.



CAUSE
This problem occurs because the ISA Server remote procedure call (RPC) application filter does not process the MSRPC requests from the Macintosh client correctly.



WORKAROUND
To work around this problem, Macintosh clients can use Post Office Protocol version 3 (POP3) or Internet Message Access Protocol, Version 4rev1 (IMAP4) for mail retrieval and Simple Mail Transfer Protocol (SMTP) to send mail. Macintosh clients can also use Outlook Web Access (OWA) as their mail client.



STATUS
Microsoft has confirmed that this is a problem in Microsoft Internet Security and Acceleration Server 2000.

Additional query words: Macintosh MAPI ISA MSRPC Stingray
