I am planning to co-exist Zimbra with Microsoft Exchange 2010. Requirement is send and receive emails between Zimbra and Exchange. GAL Sync. Free-Busy.
And there will be separate mailboxes for the two different mail servers.
MS Exchange 2010 mailboxes
For example the mails send to user1, user2 and user3 should go to Zimbra Server and mail send to user4, user5 and user6 should go to Exchange 2010 server.
I have configured the Exchange Server to send email to Zimbra when the mailbox is not in the Exchange 2010 Server. Now I need to configure Zimbra to send email to Exchange when the mailbox in Exchange. Please assist me on this regard.
Also I need kind help on GAL Sync and Free/Busy.
