IMac using Office 365 Sequoia 15.1.1 2 days ago Outlook started Displaying a PUID string as part of "From" email address

A couple of days ago I noticed the From email address has started including a PUID string. The From address is a gmail address now shown in brackets. The mail does send. The PUID string does not display in the Sent folder

What changed?

Outlook version 16.92 Microsoft 365 Subscription which is current

Imac M3 16 GB Sequoia 15.1.1

I now see the issue has PUID string disappeared, nothing tried at this end, not even a reboot?

A copy of the screen is attached, at a loss to explain...
