I am looking into the feasibility of migrating from exchange to Zimbra. I have Avaya Modular Messaging that uses exchange. I am uncertain of all the work I did for integrating it with exchange. It was a long time ago. I seem to recall I created a user that has access to everyones inbox and can check to see if mail sent by it are read. Has anyone looked at using Avaya modular messaging with Zimbra?
