This was caused by the March Security Update (SU) for Exchange. It is marked as a cosmetic issue since it shouldn't be appearing like it does (now) but doesn't seem to be breaking anything.
Released: March 2024 Exchange Server Security Updates - Microsoft Community Hub
"After installation of the March 2024 SU, newly received messages might show yellow envelope icon in Outlook client, no matter the read status of the message. This issue is cosmetic."
It will be fixed along with other issues from the March SU.
