Windows or Mac?
Will have a look when I sit down at my desk.
Windows.
You used to just be able to right click on inbox, then click add shared account. This is no longer an option. You used to also be able to do it by going to add new account, then adding a shared mailbox. That also doesn’t work any more!
There is definitely a way - we had the same issue at work last week.
IT managed to sort it, and it doesn’t exactly sit exactly the same as the old group mailboxes (it feels more like a file than an inbox)
I’ve got a feeling this is one of the current limitations of New Outlook.
Nothing like shipping a product with missing features
Certainly seemed that way from the searching I did. But I can’t even seem to get back to outlook classic now. Albeit, new laptop, so unsure if classic even exists on here. Slightly annoying as most cadet traffic I want to look at is via the generic account, which I have added as a shared mailbox normally!
Yeah I flipped at work, then very quickly flipped back!
I now have no intent of flipping until Microsoft force me
- Right click your account name “Joe.Bloggs@work.com”
- Add shared folder or mailbox
Yeah it appears under a “Shared with me” folder style view which is rubbish. not sure why MS felt the need to change that. The new Outlook on Mac still shows it the old way.
Outlook Classic should still be there, I found you need to search for it like that “Outlook (classic)” then there’s a toggle switch in the top right to “Try the new Outlook”
These are the options I get when I right click. Not what it should be!
Appears I am actually on classic, and the try new outlook is ticked to off. So now I’m more confused?
Yeah that very much looks like Classic Outlook
Try:
- Data File Properties
- Advanced
- Advanced Tab
Should then have a box saying “Open these additional mailboxes”
Click Add and enter the email address
Tried that one already. The add button is greyed out!
Also, just flicked that switch to try new outlook and now everything is broken. Certainly was still on classic, just things weren’t working as they should. Now nothing is working 
I think I should get back to my actual day job and worry about this later 
At work we run off hosted Microsoft Exchange. This isn’t compatible with New Outlook, despite both being Microsoft.
I did exactly the same, ‘New Outlook’ just wasn’t workable when I tried it, guess they may have improved it a bit by now, but I’m loath to try it.
