A Microsoft application for managing email, calendars, contacts, and tasks across devices and platforms.
Hi Nebucadneza
Thank you for posting in the Microsoft Community forum. I hope you're doing well.
I understand that you have concern about the shared mailbox in new Outlook if it would be possible to be put in the favorites. Let's work together to find the best solution to this problem.
With regards to your concern, we will investigate first on our end if this feature is available or not on the new Outlook.
In the meantime, I would like to know what is the exact name of the version of the Office application you have? Is it Microsoft 365 Family/Personal or Business? See this article for instructions: About Office: What version of Office am I using? - Microsoft Support
What is the configuration of your email on Outlook? Is it on IMAP, POP or Microsoft Exchange?
I look forward to your reply.
Sincerely
ReynaldoB
