A disclaimer is text that's automatically added to e-mail messages. Disclaimers are typically used to provide legal information, warnings about unknown or unverified senders, or for other reasons as determined by an organization.
Here's an example of a disclaimer.
IMPORTANT NOTICE: This e-mail message is intended to be received only by persons entitled to receive the confidential information it may contain. E-mail messages to clients of Contoso may contain information that is confidential and legally privileged. Please do not read, copy, forward, or store this message unless you are an intended recipient of it. If you have received this message in error, please forward it to the sender and delete it completely from your computer system.
To automatically apply disclaimers to e-mail messages, you use transport rules. You create disclaimers in the Exchange Control Panel.
Here's how to create a disclaimer that's added to the bottom of all messages sent to external recipients:
In the Exchange Control Panel, select Manage My Organization > Mail Control > Rules.
Click New. Enter the following information in the New Rule window:
Click "More Options...".
* If... Select "The recipient..." and "is external/internal". In the Select Scope window, select "Outside the organization", and click OK.
* Do the following Select "Append a disclaimer to the message..." and "Append a disclaimer".
Click "* Enter text..." to enter the disclaimer text, and click OK.
- Click "More Options...".
Click Select one... to specify a fallback action that defines what you want to do if the disclaimer can't be applied to the message. The choices are Wrap, Ignore, and Reject. The default action is Wrap. To learn more about these options, see Fallback actions.
When you are finished, click OK.
To add exceptions to the rule so the disclaimer isn't applied to specific messages, click "* Except if...". For example, to specify specific users, select "The sender..." and "Is this person" or "Is a member of this group". For a complete list of the available exceptions, see Conditions and Exceptions for Transport Rules.
- Name of rule Accept the default name, or enter a unique, descriptive name for the rule.
A disclaimer has two main components:
You also have to decide what conditions to apply the disclaimer. For example, you may choose to apply the disclaimer to all messages in your organization, or to messages sent to external recipients only. You can also specify different disclaimers for internal recipients and external recipients, or for messages sent by users in a specific departments or offices. For more information about the conditions you can specify, see Conditions and Exceptions for Transport Rules.
Note when you configure multiple transport rules to apply disclaimers, carefully consider the conditions you use and avoid applying multiple disclaimers to the same message. Also, to avoid repeatedly applying the same message disclaimer to message replies, you can add an exception that looks for the disclaimer text in the body of the message.
The disclaimer content is the text that's inserted into a message. Disclaimers are inserted into e-mail messages using the same message format as the e-mail message. For example, when an HTML disclaimer is added to a plain text message, the HTML tags are removed from the disclaimer text.
You can also modify the appearance, position, and behavior of the disclaimer within the e-mail message. You can customize the disclaimer content by using the following elements:
Disclaimer text can include HTML tags. This allows you to create messages with the rich styling functionality available in HTML. Additionally, HTML tags can include inline cascading style sheets (CSS). Messages sent in the HTML format can display the rich disclaimer messages.
You can add images to HTML disclaimers by using the
IMG tag, for example:
If you want to use images in your disclaimer, consider the following:
The images aren't embedded in the message.
The images should be located on a Web server that's accessible by the recipient.
By default, images in disclaimers aren't visible in most e-mail clients. Many e-mail clients, including Outlook Web App and Microsoft Outlook, block external images and external Web content by default. Recipients may need to select "show blocked content" or a similar action to view the images. Therefore, we recommend that you test disclaimers containing images to make sure those disclaimers meet your requirements.
You can add user attributes to disclaimers. For example, you can add
Company to create personalized signatures. When the disclaimer is added to the message, the attribute names are replaced by the corresponding values from the sender's user account. To use attributes in a disclaimer, you enclose the attribute in two percent signs (%%). For example, to use the DisplayName attribute, use
You can use the following user attributes in disclaimers.

| || || |

To clearly separate the disclaimer from the body of the e-mail message, you can use the HTML tag
<HR> to create a separator line. You can also use inline CSS styles in HTML tags to add lines or borders around the HTML disclaimer message.
You can prepend the disclaimer at the beginning of the e-mail message or append it at the end. When you prepend the disclaimer, the disclaimer is inserted at the top of the message before the text of the newest message thread. When you append the disclaimer, the disclaimer is inserted at the bottom of the message thread.
Some messages, such as encrypted messages, can't be modified so a disclaimer may not be applied as expected. You can specify what to do when a disclaimer can't be applied to a message. Here are your options:
- Wrap The original message is enclosed, or "wrapped", in a new message, and the disclaimer is inserted into the body of the new message. If the original message can't be wrapped in a new message, the sender receives an NDR that explains why the message wasn't delivered.
Note Any subsequent transport rules are applied to the new message, not the original message. Therefore, you should make sure that a rule that adds a disclaimer with the Wrap fallback action always runs last.
- Ignore The original message is delivered without the disclaimer.
- Reject The message isn't delivered. The sender receives an NDR that explains why the message wasn't delivered.
The following is an example of an HTML disclaimer with an
IMG tag and embedded CSS.
