We are trying to attach to a sendmail server using
STARTTLS, and get the error message shown in KB article
832566. The resolution listed in KB article 832566 is to
turn off SSL in Outlook. Is this really the only solution?
Is Outlook really incompatible with SSL? Does a fix for
this problem have an expected availability date? Thanks for
your help.

Is the server using a self-signed certificate or something from
verisign/thawte/.etc?
 
Does the workstation hold a copy of the internal CA root certificate? (I
learned the hard way that Outlook 2003 will throw no error messages when
trying to do RPC over HTTPS and u don't have the internal root CA installed.
Just never connects. POP/IMAP might actually bubble up an error code. Will
have to check to see.)

By the way, don't forget to Jeff about what version of Outlook you are
running since each version of Outlook tends to behave differently. ;)
 
Jeff,

Sorry, I missed seeing your reply. It's Outlook 2000.
Thanks for your help.

I don't think Outlook 2000 supports TLS, only SSL, because the encryption
code it uses was written before the TLS standard. Outlook 2002 and 2003
both support either SSL or TLS.
