XCLN: Sending Messages In Rich-Text FormatLast reviewed: September 23, 1997Article ID: Q136204 |
The information in this article applies to:
SUMMARYThe 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 listsYou 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 CONCEPTBy 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 will cause 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. 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: 7bitFollowing 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'" `$``<`)P`V``4`1P$!

Only Microsoft Exchange and messaging systems compatible with rich- text formatting can translate the formatting details contained in the MIME encoding and in WINMAIL.DAT.
TOGGLING RICH-TEXT FORMATThe following scenarios outline when a message sent though the Internet with Microsoft Exchange will be delivered in rich-text format.
New Address Book EntryRich text is a property that can be set per recipient with the Internet Mail Provider. You can set the rich-text option in the personal address book by choosing New Entry from the Address Book File menu, and selecting Internet Address. By default, rich-text formatting is off for new entries.
Adding Address Book Entry from MessageIf you receive mail from a sender that is not in your personal address book, you can add that person by examining the details on that sender (double-click the sender's alias name in the From box), and clicking the Add To: Personal Address Book button. The new entry will have rich-text formatting off by default for the alias you are creating. You can select (check) the Always Send To This Recipient In Microsoft Exchange Rich-Text Format check box to turn on rich-text formatting for the new alias. This setting will be used when you choose the name from the address book for both of the above examples. NOTE: The above two examples are true for the Microsoft Exchange Internet Provider that ships with Microsoft Plus! for Windows 95. Other providers may have different defaults.
Entering Address in [smtp:user@domain.net] FormatInstead of choosing an alias from the personal address book, you can use one of two forms of "one-off addressing." One-off addressing allows you to enter an alias directly in the To box when you compose a message. The first form of one-off addressing is to type the address enclosed in brackets with the SMTP address designator. Messages addressed in this format will be delivered in rich-text format. Example:
TO: [smtp:postmaster@company.com] Entering Address in user@domain.net FormatThe second form of one-off addressing is to enter the address without enclosing the address in brackets. Messages addressed in this format will NOT be delivered in rich-text format. Example:
TO: postmaster@company.comNOTE: For the above two examples, you can toggle the rich-text setting using the following steps:
