Workaround: Send a test email to your shared inbox from New Outlook. This populates the address locally, which allows you to find it when trying to add the shared inbox.
I, like many others, have been unable to add a shared inbox from Microsoft 365 to Outlook for Mac via the new interface.
Both the "Delegate and sharing" under my account, and the "Open a Shared Inbox" under Tools>Accounts did not function for all but, strangely enough, one of my shared inboxes.
I spent an hour on the phone with Dale from Microsoft Support last night, working through permissions, settings, outlook.com web, and old outlook. Both legacy Outlook and outlook.com were able to add the additional inboxes, but no luck with new Outlook.
But then I had a eureka moment this morning...
I realized, the only shared inbox I was able to add to New Outlook, was one I had sent a test email to, to verify it was working. This caused it to show up in the list of available inboxes. Strangely, I had also sent an email to info@chemex, which when I searched for an "info" shared inbox I own, that showed up in the list.
This led me to sending a test message to all my shared inboxes. As a result, I was able to add them all in the new Outlook for Mac.
It seems like the "Shared Inbox" function is not correctly connecting to the M365 service to populate the list of available inboxes in New Outlook, and it doesn't have the same option to force it that old outlook and outlook.com do. Add back the "use <email>" option when no search results are found, and it should fix this.
Good luck!
