Exchange, Zimbra, or others - assistance is needed

OTAdmin used Ask the Experts™
We are looking to replace our Exchange 2003 server.  I'm open to any option at this point.  Here are some things that are important to us:

- delegates - executive assistants sending on behalf, viewing cal, contacts, etc
- shared contacts - these are contacts outside the GAL, common external contacts for use across organization, accessible from smart phones!!!
- multiple domains - we have several separate organizations on the same server
- Outlook integration
- shared calendars

I could go with Exchange 2010, although I would probably go a hosted route.  I could go Zimbra, but I don't know enough about it.

The problems - execs are really used to delegates accessing their accounts.  Users are used to public folders (central calendar and contacts).

Any suggestions?  I just could go with Exchange and be done...but it is just such a beast, which is why I'm looking into alternatives or hosted Exchange.

Anyone have any thoughts?

Have you considered GMail?
Especially good if you have more than one office or working location.

We've just moved to it and I like. it!

In fact I've been able to get rid of Windows completely in favor of a Linux desktop, now that I don't need Outlook.
That whole issue of software licensing is just gone.
Of course that won't suit everyone but it suits me just fine.
