Using Classic Outlook on Windows for personal email, calendar, and contact management
I'm with you. Same version as poster but there's no way to add any of my shared mailbox folders to my favorites (in particular interest the "inbox" of mailboxes under "Shared with me".)
Now if I ADD the account to Outlook the inboxes appear but for some reason I can't seem to add the one account I need the most. It just throws an error. I thought I read somewhere that licensing on the target account was the problem but I haven't found that info since.
REGARDLESS I still can't move email messages from one in-box to the other. We use a help desk software that monitors an exchange mailbox. In Original outlook when someone emails our team and we need to create a ticket from the email, we drag it into the Inbox the help desk software is monitoring. That's still not a function in New Outlook.
