PROBLEM

After you make a change to a data loss prevention (DLP) policy, the change doesn't take effect in Microsoft Outlook 2013 in Office 365. For example, you experience one or more of the following symptoms:
  • Policy tips aren't displayed correctly when the conditions in the DLP policy are met.
  • Messages aren't appropriately blocked by the DLP policy.
You experience these symptoms even though the DLP policies were working correctly before the change was made.

CAUSE

This problem occurs if the updated DLP policy wasn't downloaded to Outlook 2013. Outlook 2013 checks for changes to DLP policies one time every 24 hours.

WORKAROUND

Important This section contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, see the following Microsoft Knowledge Base article:
322756 How to back up and restore the registry in Windows

Let me fix it myself

To work around this issue, force Outlook 2013 to download the updated DLP policies. To do this, follow these steps:
  1. Use Registry Editor to remove existing DLP policies that are applied to Outlook 2013. To do this, follow these steps:
    1. Exit Outlook 2013.
    2. Click Start, click Run, type regedit, and then click OK.
    3. In Registry Editor, locate the following subkey:
      HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\15.0\Outlook\PolicyNudges
    4. Delete the LastDownloadTimesPerAccount registry entry.
    5. Exit Registry Editor.
  2. Start Outlook 2013, create a new message, and then type some text. When you do this, you force Outlook 2013 to download DLP policies.
