- question: |
Why aren't users receiving notifications about their quarantined messages?
answer: |
First, use [message trace](message-trace-defender-portal.md) to confirm that the recipient didn't receive a quarantine notifications:

- **Sender**: `[email protected]` or a [custom sender address](quarantine-policies.md#configure-global-quarantine-notification-settings-in-the-microsoft-defender-portal).
- **Recipient**: The recipient's email address.

After you confirm that quarantine notifications weren't sent, proceed with the following guidance.

If the quarantine policy that's defined for the [supported quarantine action](quarantine-policies.md#step-2-assign-a-quarantine-policy-to-supported-features) doesn't have notifications turned on, the quarantine notifications aren't sent.

For more information, see the last table in [Anatomy of a quarantine policy](quarantine-policies.md#anatomy-of-a-quarantine-policy) and the individual feature tables in [Recommended settings for EOP and Microsoft Defender for Office 365](recommended-settings-for-eop-and-office365.md) to see which default quarantine policies have quarantine notifications turned on.
