Manage policy tips in Exchange Online

Policy Tips are informative notices that are displayed to email senders while they're composing a message. The purpose of the Policy Tip is to educate users that they might be violating the business practices or policies that you are enforcing with the data loss prevention (DLP) policies that you have established. The following procedures will help you begin using Policy Tips. Watch this video to learn more.

What do you need to know before you begin?

  • Estimated time to complete each procedure: 30 minutes

  • You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "Data loss prevention (DLP)" entry in the Feature permissions in Exchange Online topic.

  • Policy Tips will only show up for email senders when the following conditions are met:

  1. Sender's message client program is Microsoft Outlook 2013 or later. (For a list of the Outlook client versions/licenses that support DLP Policy Tips, see Outlook license requirements for Exchange features.) If your organization has deployed Exchange 2013 SP1 or later, or is using Exchange Online, Policy Tips also show up in Outlook on the web (formerly known as Outlook Web App) and OWA for Devices.

  2. A mail flow rule (also known as a transport rule) exists that invokes Policy Tip notifications. You can create such a mail flow rule by configuring a DLP policy that includes the action Notify the sender with a Policy Tip.

  3. The content of a message header, message body, or message attachment meets the conditions established within the DLP policies or rules that also include Policy Tip notification rules. Put another way, the Policy Tip only shows up for end-users if they do something that causes the associated rule to take action.

    • The default Policy Tip notification text that is built into the system will be shown if you don't use the Policy Tip settings feature to customize your Policy Tip text. To learn more about the default text, see Policy Tips.

    • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard shortcuts for the Exchange admin center.

Keep in mind that there are default system Policy Tip notifications that can be shown if you do not customize your Policy Tip notification text. To learn more about the default text, see Policy Tips.
