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.
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

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

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``P```! `#D`X!.6)7ABN@$>`' ``0```!@```!;<VUT<#IG:W5D87-Z0&-R
[. . .]
Note that the MIME encoding and WINMAIL.DAT information are not legible
text. 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 FORMAT
The following scenarios outline when a message sent though the Internet with Microsoft Exchange is delivered in rich-text format.
NOTE: The following examples are true for the Microsoft Exchange Internet Provider that ships with Microsoft Plus! for Windows 95. Other providers may have different defaults.
New Address Book Entry
Rich 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 clicking
New Entry from the
Address Book File menu, and clicking
Internet Address. By default, rich-text formatting is off for new entries.
Adding Address Book Entry from Message
If 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
Add To: Personal Address Book. The new entry has rich-text
formatting off by default for the alias you are creating.
You can click to select 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 is 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] Format
Instead 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 are delivered in rich-text format.
Example:
TO: [smtp:postmaster@company.com]
Entering Address in user@domain.net Format
The second form of one-off addressing is to enter the address without
enclosing the address in brackets. Messages addressed in this format are
NOT delivered in rich-text format.
Example:
TO: postmaster@company.com
NOTE: For the above two examples, you can toggle the rich-text setting
using the following steps:
- Click Check Names on the toolbar, or press CTRL+K.
- Double-click the alias name in the To box.
- Either click to select or click to clear the Always Send To This Recipient
In Microsoft Exchange Rich-Text Format check box, as applicable.
