SYMPTOMS

When you use Internet Security and Acceleration Server (ISA) to publish an Exchange server and give external clients permission to connect to an internal Exchange server, x86-based Outlook clients can connect to the Exchange server, but Macintosh Outlook clients cannot connect to the Exchange server.

CAUSE

This problem occurs because the remote procedure call (RPC) filter (Rpcfltr.dll) included with ISA cannot convert the big-endian format of a Macintosh UUID to little-endian format.
