Using Classic Outlook on Windows for personal email, calendar, and contact management
Adding a mailbox to a favourite in that way seems to be a filter for emails that YOU received from that mailbox. It's pretty useless.
I also desperately need to see the INBOX at least of several shared mailboxes.
Agreed,
Aboslutely useless, I've just messaged my colleagues to say 'Good news' you can add the shared mailboxes in as favourites on new outlook, but now were going to miss most of the emails as its not sharing the inbox its filtering only emails ive previously responded to in the old version of Outlook!
We need to genuinely share an inbox, genuinely see how many emails haven't been responded to etc. It costs us £11 per user per month and the only app we really use is One drive and Outlook, we rarely need to use anything else as we have apps for all the things that we do, looks like we might be needing a new email app too now.
