We are currently operating with Novell's OpenExchange collaboration suite OpenExchange 4.1.

I am considering testing Zimbra, but two things are making me hesitate.

1) How do we migrate our existing email in OpenExchange to Zimbra? I'm not overly concerned about calendar and files, but I have to find an easy way to migrate the email.

2) We have several hundred "global" or "Universal" email folders that allow our employees to save email in. This means we can put all emails involving a client into one folder. I have seen it mentioned that Zimbra does have "shared email" but I was wondering how that worked.

I suppose we could just make a universal user, much like Cyrus in OpenExchange, and then share it to everyone that needs it.

Thanks for your help.
