AT&T PROVIDES WINDOWS 95 USERS ACCESS TO GLOBAL MESSAGING SERVICES.

PARSIPPANY, N.J.--(BUSINESS WIRE)--July 26, 1995-- AT&T has developed software that will give users of the upcoming Microsoft Windows 95 operating system access to secure and reliable communications through the AT&T Mail global network.

The software is designed to provide a seamless link between the AT&T Mail service and software programs that comply with Microsoft's MAPI 1.0 (Messaging Application Program Interface), which is part of the Windows 95 operating system. MAPI gives users an easy method of integrating programs and communications, a feature of increasing value as communications becomes a critical centerpiece in computing. Just as users can now use menus within Windows to select printer drivers, MAPI allows users to similarly select their communications needs for message-enabled applications. With such applications, communications features can be used from within the application rather than having to exit in order to use a separate communications package.

The AT&T software will be provided for free to users of Windows 95 and Windows NT in the United States who request it from AT&T beginning August 24. To order the software and establish an account to use the global messaging offering of AT&T Mail, persons can call 1-800-242-6005, Dept. Win95.

The software is formally known as AT&T Mail Platform for MAPI 1.0. This messaging platform provides users of Windows 95 and Windows NT with a variety of benefits:

o Support for AT&T Mail, a leading electronic mail service with

service to more than 160 countries and connections to all major

e-mail systems in the U.S. and around the world. Users can also send

and receive electronic mail through the Internet, giving users

access to the most popular use of the growing global network --

electronic mail.

o Custom addressing templates that assist the users in creating and

sending e-mail messages.

o Users can create a single or multi-part message, address it to any

number of recipients (using To, Cc and Bcc options), select various

message or recipient options, and send it to the AT&T Mail service

for delivery.

o Support for enhanced fax features that allows users to receive, view

and print faxes.

o An architecture optimized to support both the Windows 95 and Windows

NT operating systems.

o Support for Electronic Data Interchange (EDI), the

computer-to-computer exchange of standardized information. EDI is

rapidly emerging as one of the key elements of electronic commerce.

o Sending of full, multi-part and multimedia messages through the

Internet or any other systems that support Simple Mail Transfer

Protocol (SMTP) or the Multipurpose Internet Mail Extension (MIME)

protocol. With MIME, users can send multimedia e-mail messages that

include audio, video, graphics, and text to any other user of a

TCP/IP network.

AT&T Mail Platform for MAPI 1.0 will be available concurrent with the release of Microsoft Windows 95. The AT&T software has started shipping for evaluation and testing to independent software vendors, MIS groups within corporations and others interested in providing end-users with powerful communications capabilities.

AT&T and Microsoft have collaborated for several years to develop a suite of products that provide connectivity from Microsoft messaging software to AT&T Mail. AT&T MailPower Solutions for Microsoft Software include:

o AT&T Mail Platform for MAPI 1.0

o AT&T Mail Gateway for Microsoft Mail 3.x

o AT&T Mail Driver for Microsoft Mail Remote for Windows 3.x.

AT&T EasyLink Services offers one of the broadest arrays of electronic messaging services in the market, including electronic mail, a full suite of information services, as well as Electronic Data Interchange (EDI). AT&T EasyLink Services supports access to these services from all types of devices and systems, including PCs and terminals, hand-held mobile devices, Macintosh computers, host and UNIX Systems computers and electronic mail systems on Local Area Networks.
