Upgrading to Outlook 2000

Sharing Information with Microsoft Mail 3.x

Microsoft Outlook 2000 can exchange messages with users of Microsoft Mail 3.x for Windows. Outlook 2000 recognizes all Microsoft Mail 3.x message properties. However, Microsoft Mail 3.x users might not be able to view or use portions of Outlook 2000 messaging information.

Although Outlook 2000 works with Microsoft Mail post offices, the full set of Outlook 2000 features is available only when you use it with Microsoft Exchange Server. The following Outlook 2000 features require Microsoft Exchange Server:

• Opening e-mail folders as a delegate of another user
• Security for “Sent on behalf of” messages
• Deferred delivery and message expiration
• Digital signatures and encryption
• Public folders
• Full-text search

In addition, Microsoft Mail 3.x and Outlook 2000 cannot share the same message store. To use data from a Microsoft Mail 3.x message store, users must import the message store to an Outlook-compatible format. Microsoft Exchange Server includes a utility that imports Microsoft Mail 3.x message stores to Messaging Application Programming Interface (MAPI) format.
