Internet & Networking Microsoft dropped support for Exchange 5.5 on December 31st, 2004. Exchange 5.5 users can upgrade to Exchange Server 2003, continue to run 5.5 with all accompanied security risks, or switch over to another mail/groupware system.In this article I propose a fourth option that is really options two (run Exchange) and three (run another mail system) combined.

other exchange replacements...

It seems that, by the time you get this going, you would have been better off to have just implemented one of the many Exchange drop-in replacements that run on Linux and that way you would be totally free from Exchange - especially an old and unsupported version.

The problem with this solution is that it really limits that length of time you can run this configuration without ditching Exchange completely. It also severely limits the scalability of the system (although, if the company isn't growing, then that's not too much of a problem).

However, it's probably a good start to moving away from Exchange if you are the type that doesn't like really large cutovers and prefers a step by step approach to migrations.

The Exchange drop in replacements are not really drop in replacements. I've been trying for years to wean companies off of Exchange, but Outlook doesn't really work properly except when teamed with Exchange. Case in point, SuSE Open Exchange. SLOX is touted as a drop in replacement, it is most definitely not, it doesn't import addressbooks or calendar data, so there is no real migration. The Outlook client plugin is problematic (there are two, one that does a scheduled sync, another that works with MAPI). Outlook clients experienced so many inconsistent problems, with SLOX. Everything from losing the public addressbook to not seeing calender entries that they just made.
Kolab2 is great and once the plugin for Outlook is ready (and working seamlessly), Exchange can be ditched.

As in a previous post...

I use Samsung Contact (HP Openmail). It works with MS Outlook (and has a web and mobile (PDA) interface), does shared calendars, contacts, and other groupware functions, and runs on a Linux machine instead of a Windows OS.

I saved $3000 in intial costs from upgrading to Exchange 2003 and it has worked out great for me.
