- Device & OS
- not provided
- Scenario
- Composing or managing emails containing sensitive data where DLP policy warning tips are expected to trigger but do not appear.
- Observed behavior
- DLP policy tips are not showing up in the email client, which may be caused by incorrect MailTips settings, cached data, unsupported conditions in older clients, or sync delays.
Verify that your Microsoft 365 account has an active network connection and ensure your administrator has correctly configured and assigned Data Loss Prevention policies to your user account.

Frequently Asked Questions
How long does it take for new DLP policies to appear in Outlook 2013?
Outlook 2013 evaluates and checks for changes to Data Loss Prevention (DLP) policies approximately every 24 hours. If an administrator recently updated a policy, you must wait up to a full day for the changes to reflect in your client.
Why do DLP policy tips show up in Outlook on the Web but not in Outlook 2013?
Outlook on the Web processes DLP rules directly on the server, ensuring full compatibility with all modern Microsoft 365 policies. Outlook 2013 is an older client and only supports a limited subset of conditions and exceptions. If a policy uses unsupported conditions, the tip will simply not display in Outlook 2013.
Can I manually force Outlook 2013 to update its DLP policy cache?
Yes, but it typically requires using the Microsoft Support and Recovery Assistant (SaRA) diagnostic tool or manually clearing specific registry keys related to the Office PolicyNudges cache. Using the automated Microsoft DLP diagnostic tool is the safest and recommended method.
Are MailTips and DLP Policy Tips the same thing?
They are related features. DLP Policy Tips are technically delivered through the MailTips infrastructure in Outlook. Therefore, if MailTips are disabled globally in your Outlook Options, DLP Policy Tips will also fail to display.
