Well, the first part of your statement is debatable (that they are not
"Open Source"), but the second part is fact .. they do not use OSI
approved licenses. So, if your definition of "Open Source" is an OSI
approved license, then they are not open source.
What's more, in all of these cases full outlook capability is not
provided in the "Free" version anyway.
Outlook calender/meeting functionality requires (in almost all the
solutions) a really non open source (proprietary and not compilable)
program to make use of the proprietary outlook/exchange interface called
MAPI. Most of the free versions of these mail systems use IMAP, with
will not properly be used by outlook to do calander functions ... and
they charge for the outlook MAPI client, which will allow for outlook
calender/meeting functions.
