Enable or disable security alerts on the Message Bar

The Message Bar displays security alerts when there is potentially unsafe, active content in the document you open. For example, the document might contain an unsigned macro or a signed macro with an invalid signature. In such cases, the Message Bar appears by default to alert you about the problem.

If you don't want to be alerted, you can disable the Message Bar.
