Provide required information needed to triage your issue

Mac Outlook client does not fire off the onMessageFromChanged event in the add-in when the sender changes.

Your Environment

• Platform [PC desktop, Mac, iOS, Office on the web]: Mac
• Host [Excel, Word, PowerPoint, etc.]: Outlook
• Office version number: 16.92 (24120731)
• Operating System: macOS Sequoia 15.2
• Browser (if using Office on the web): N/A

Expected behavior

When composing an email, changing the sender to another mailbox in the same account to send an email on behalf of someone else, the onMessageFromChanged add-in event should be triggered. It does work as expected on other clients, just not mac (OWA, Windows, Android, iOS).

Current behavior

Currently, when the 'From' field is changed to another email address within the same account, the event is not fired and the add-in does not run.

Steps to reproduce

1. Compose an email
2. Change 'From' to another email address within the same account
3. onMessageFromChanged does not work
