DOCUMENT:Q136204 02-FEB-2002 [exchange] TITLE :XCLN: Sending Messages In Rich-Text Format PRODUCT :Microsoft Exchange PROD/VER::95 OPER/SYS: KEYWORDS:kbusage ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - the operating system: Microsoft Windows 95 - Microsoft Plus! for Windows 95 - Microsoft Exchange Server, version 5.5 ------------------------------------------------------------------------------- SUMMARY ======= The Microsoft Exchange Windows 95 client allows you to send messages through the Microsoft Exchange Internet Provider in rich-text format. To view rich-text attributes, the recipient must also use Microsoft Exchange or another messaging system that displays rich-text formatting. Messaging systems that do not support rich-text formatting will display messages as plain text without special attributes or formatting. Rich-text format attributes include: Font name Font size Character color Bold Italic Underline Strikethrough Bulleted lists You may want to disable rich-text formatting in messages sent to recipients whose e-mail systems do not decode and display these attributes. MORE INFORMATION ================ Properties Concept ------------------ By default, when you send a rich-text message using the Microsoft Exchange Internet Mail Provider, a MIME-encoded description of the formatting is included with the message. You can also send messages without MIME; this causes a special file to be attached called Winmail.dat. Winmail.dat is appended to the message in uuencoded format. This encoding includes rich-text attributes and formatting details for the mail message. For additional information about how to prevent sending the Winmail.dat attachment to Internet users when you are using the Microsoft Exchange Internet Mail Service, click the article number below to view the article in the Microsoft Knowledge Base: Q138053 XFOR: Preventing WINMAIL.DAT Sent to Internet Users When a rich-text format message is sent using MIME, an entry similar to the following is added to the header of the message: Mime-Version: 1.0 Content-Type: multipart/mixed; boundary="---- =_NextPart_000_01BA6275.348C1000" Status: RO X-STATUS ====== ------ =_NextPart_000_01BA6275.348C1000 ------ =_NextPart_000_01BA6275.348C1000 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Following the header is the message body, followed by MIME-encoded rich-text formatting information similar to the following: ------ =_NextPart_000_01BA6275.348C1000 Content-Type: application/ms-tnef Content-Transfer-Encoding: base64 eJ8+IisSAQaQCAAEAAAAAAABAAEAAQeQBgAIAAAA5AQAAAAAAADoAAENgAQAAgAAAAEAAQ ABBJAGAEgBAAABAAAADAAAAAMAADACAAAACwAPDgAAAAACAf8PAQAAAHQAAAAAAAAAtTvC wCx3EBqhvAgAKypWwhUAAAB2ZPLzl7rOEa5RAKoAQkrnpIAAAAAAAACBKx+kvqMQGZ1uAN 0BD1QCAAAAAEdyZWcgS3VkYXN6IChhdCBjcmlzLmNvbSkAU01UUABna3VkYXN6QGNyaXMu Y29tAB4AAjABAAAABQAAAFNNVFAAAAAAHgADMAEAAAARAAAAZ2t1ZGFzekBjcmlzLmNvbQ AAAAADABUMAQAAAAMA/g8GAAAAHgABMAEAAAAcAAAAJ0dyZWcgS3VkYXN6IChhdCBjcmlz LmNvbSknAAIBCzABAAAAFgAAAFNNVFA6R0tV [. . .] Alternatively, when a rich-text formatted message is sent using UUENCODE, code similar to the following is added to the bottom of the message: begin 600 WINMAIL.DAT M>)\^(C<.`0:0" `$```````!``$``0>0!@`(````Y 0```````#H``$%@ ,` M#@```,L'" `$``<`)P`O``4`0 $!"8 !`"$````S,S5$,C,W,#%"0T-#13$Q M04,S,C4R-#$U,S0X,# P,0#8!@$@@ ,`#@```,L'" `$``<`)P`V``4`1P$!
