OpenXchange is an excellent competing product.  There is more current
information on their retail site:

Do you mean OpenXchange (recently moved to the US from Germany - now or the related SuSE OpenExchange (SLOX) now owned by
Novell (
Neither of them are 'free'.  Both have commercial retail versions.
Besides, Open Source <> Free.

Ultimately, Microsoft Exchange Server 2003 still performs better, integrates
into AD easier and provides the most efficient user experience (MAPI,
Cached-mode, a better OWA), better mobile client services, greater adoption
worldwide.  But depending on the potential client's needs and resources, an
alternative to Exchange Server might be a better fit.

Hi all,

Any comments on Open Exchange?  Anyone used it?

This is an open source (i.e. free) product.  I have a customer who seems
very interested in it so I wanted to talk to him intelligently about MS
Exchange vs Open-Exchange, technical pros and cons (not just mareting pros
and cons like "MS is a big company, Open-Exchange is an unknown, no support

Best regards
Mike Salim
