"Microsoft Email Clients" … what is it? Outlook? Version? Exim is
compatible with clients that follow the internet standards, especially
for the message transport (SMTP protocol) and the message format. See
RFC5322 and RFC5321.

Additionally related standards exist, defining Transport Layer Security,
and other things.

Though back to the root problem, multiple copies of mail. As Jeremy
already requested, we need log lines and a somewhat more detailed
description:

- What did you do?
- What did you observe?
- What did you expect?

There is a small "gap" in the SMTP protocol, that can cause
re-transmissions of messages that are sent already. I've seen it with
clients from Microsoft, not following the timeout recommendations from
the above mentioned RFCs. It happened, whenever the client closed the
connection while Exim was still doing the content scan. (timeout after sending
the trailing dot.)
