OnMessageRecipientsChanged is fired when previewing draft mails

Provide required information needed to triage your issue

When I save an email and preview it in the draft mode the "OnMessageRecipientsChanged" is fired along with "OnMessageCompose"

Your Environment

• Platform: PC
• Host : Outlook
• Office version number: 16.0.17531.20140
• Operating System: Windows 11

Expected behavior

OnMessageRecipientsChanged should not be fired when previewing draft mails.

Steps to reproduce

1. Create a new mail and save it so that it is stored in the drafts
2. Go to the draft folder and preview the draft in read mode
3. Observe in the logs that the event is fired

Context

We are listening to this event to render a signature based on the recipients. We have unnecessary renderings.

I also realized that "onMessageRecipientsChanged" is also fired when replying to an email. That should also not happen and is inconsistent with the web version.

Thanks for reporting this issue regarding signature bookmark. It has been put on our backlog. We unfortunately have no timelines to share at this point
