At least, it sounds like, you're not using Public Folders. (-:

Perhaps helpful:


(Think how much of MS Word's functionality is typically used vs what 
it's capable of. i.e. Hard to answer the question of Exchange 
equivalent without knowing how much of Exchange you're actually using. 
Which you've now answered.)

Active Directory is usually the sticky wicket in considering 
alternative. Do you require the alternative to validate against AD? 
Are you willing to set up your own LDAP server and get it and AD to 
coexist together in some fashion?

	I expect losing AD entirely is not an option for you. So, do you 
require a single point of user id maintenance, which by definition 
would have to be AD, or is it acceptable to have two? For that matter, 
you may already have two points of maintenance, if you're running Samba.

Sorry, no personal experience myself. Certainly interested in hearing 
the answers to your question though.
