How to Take a Message Out of Read-Only Mode
If you need to edit a message that is in read-only mode, you can easily turn off the protection to be able to edit it with just a few clicks.
If you clicked "Edit Message" and you see something like the screenshot below, you just need to turn off a toggle in the List Settings.

Follow these steps to take the message out of read-only mode and make your edits. Once you're finished, be sure to put the message back in read-only mode to avoid any accidental changes.
- From the My Lists page, click directly on the name of the list to open the List Details page.
- Click the List Settings button.
- The toggle for Disable deleting current message will be turned on. That toggle is what puts the message in read-only mode. Turn the Disable deleting current message toggle OFF.
- Click the double back arrows in the upper left to return to the previous page.
- Click the Edit Message button.
- Use the Next button to proceed through the message creator tool, and edit your message as needed.
- On the final message sending page, click Save to save your changes.
- Finally, click the List Settings button again and turn the Disable deleting current message toggle back ON to make sure no one makes changes to the message accidentally.
