Microsoft Mail 3.1

There were two distinct "Microsoft Mail" products. One for AppleTalk Networks, and one for PC Networks.

(WANTED) Microsoft Mail for AppleTalk Networks was introduced in 1988 and based off of InterMail from Interactive Technologies, Inc. Later versions had a DOS client for PCs using AppleTalk. It later became Quarterdeck Mail, then Star Nine Mail.

The Microsoft Mail for PC Networks product was introduced in 1991. It was based on Network Courier by Consumers Software of Vancouver BC. The 2.x versions were basically a rebranding, while 3.x version introduced many more features. (There was no 1.x from Microsoft) It is a shared file post office based mail server designed to work with IBM, Microsoft, and Novell network file shares.

In 1996, Microsoft Mail was replaced with Microsoft Exchange.
