Have you RTFMed? 

http://sendmail.org/ has, under the section "Primary Sources for
Information":

please read the FAQ[1], as well as Compiling[2] and Configuration[3]
before asking any questions.

[1] http://sendmail.org/faq/
[2] http://sendmail.org/compiling.html
[3] http://sendmail.org/m4/readme.html

Under the Configuration link, the table of contents refers you to a page
about SMTP authentication:
http://sendmail.org/m4/smtp_auth.html

The relevant parts of it are the parts where sendmail is a SMTP client
to another SMTP server (the MS-Exchange server, in this case).

BTW: you really don't have to use sendmail. You can use just about any
other mailer that provider a /usr/sbin/sendmail program . postfix, exim
and qmail will also do. I personally prefer postfix. Generally stick to
the default one of your distro if you don't have a good reason to change
it, as it will probably be the most maitained.

The problem with msmtp and similar programs (ssmtp, nullmailer) is that
they don't queue. Thus if there was a temporary problem at the network
or the recieving side, the message is lost.

And frankly, you may not want every message from the crond to end over
remotely.
