Windows 95 includes MAPI drivers for the Microsoft Mail e-mail system. This means that the Microsoft Exchange client can send and receive mail as a member of a Microsoft Mail network — either a full, enterprise-wide mail system, or a local workgroup mail system that uses the Windows 95 built-in Microsoft Mail Postoffice. Microsoft Exchange clients can fully interoperate with existing Microsoft Mail clients on other platforms, although rich-text messages are converted to plain-text messages when sent to an existing Microsoft Mail client.
In addition, since the Microsoft Exchange client supports OLE 2.0 and the Microsoft Mail 3.2 client supports OLE 1.0, a conversion is applied automatically to ensure that embedded objects can be sent back and forth without problems.
