• Require Application Add-ins to be signed by Trusted Publisher Check this box to have the Trust Center check that the add-in uses a publisher's trusted signature. If the publisher's signature hasn’t been trusted, the Microsoft 365 program doesn’t load the add-in, and the Trust Bar displays a notification that the add-in has been disabled.

• Disable notification for unsigned add-ins (code will remain disabled) When you check the Require Application Extensions to be signed by Trusted Publisher box, this option is no longer grayed out. Add-ins signed by a trusted publisher are enabled, but unsigned add-ins are disabled.

• Disable all Application Add-ins (may impair functionality) Check this box if you don't trust any add-ins. All add-ins are disabled without any notification, and the other add-in boxes are grayed out.

Note:This setting takes effect after you exit and restart your Microsoft 365 program.

While working with add-ins, you may need to learn more about digital signatures and certificates, which authenticate an add-in, and trusted publishers, the software developers who often create add-ins.
