Please ensure you have the latest version of Daylite installed, running on macOS 14.4 or later. Additionally, ensure that you have [Daylite installed correctly,](https://support.marketcircle.com/article/114-how-do-i-install-or-manually-update-daylite-on-my-mac) including not having multiple copies installed on your Mac.

If you continue to experience this issue, follow the steps below:

1. Quit both Daylite and Mail.
2. Launch Daylite.
3. Launch Mail and select the email again.

If the issue persists, restart Daylite Mail Assistant by turning it off in System Settings, then restart your Mac. You can do that by following the steps below:

1. Quit Mail
2. Click  in the top left corner of your display and select **System Settings...**
3. Select **Privacy & Security** > **Extensions** > **Added Extensions** and turn off `com.apple.email.extension` in the section for Daylite
4. Restart your Mac
5. Open Mail, turn on the extension by going to Settings > and check again

{% hint style="info" %}
**Why do some messages work when others don't?**

When the extension fetches email data for a viewed message, it stores it in a separate database for the helper to read. If the Mail Assistant extension crashes and subsequently a previously unseen email message is selected in Mail, its data will not get captured, resulting in this error.
{% endhint %}

If the issue persists after restarting the Daylite Mail Assistant, [contact suppor](mailto:support@daylite.app?subject=Daylite%20Mail%20Assistant%20Could%20Not%20Look%20Up%20the%20Selected%20Message) for further assistance.
