Functionality questions for Exchange migration

Functionality questions for Exchange migration

Hello,
 
Our orgainization is considering migrating to zoho mail from an existing Exchange 2003 environment.  I've done some forum searching, and have played with the mail interface a bit, but am having trouble finding answers to some specific questions.
 
1) We use resource booking via exchange currently.  So, if an employee wishes to use Conference Room A and Projector A, they include these two resources on the invite and they are automatically "booked" to avoid conflicts.  How can this be done in zoho mail?
 
2) We have several shared mailboxes that multiple users need access to.  Currently we have them set up as Public Folders with post items.  This allows all employees to have access to these mailboxes without requiring me to individually configure each new user/account in our system.  I see how to create groups in zoho mail, but I don't see how to create a common mailbox under that group.
 
3) Basically the same question with Calendar.  We're currently configured to have each user share their calendar, but also have some common "group" calendars to show office users on vacation, trade show schedules, etc.  I again don't see a group calendar option anywhere in the UI, and some forum posts said it either didn't exist or was an upcoming feature, but all the postings I found where a year old.
 
Thanks for your assistance.
