"New" Outlook: Add Shared Mailbox to Favorites

Same here, it must depend on how the additional mailbox is added. Mine is under "Shared with me" which was added by IT and I can't add that email account to Favourites. Adding the email account using the email address and password should work.

If it's a shared mailbox in a business tenant, chances are it will have been shared by IT - that's certainly how we do it. It then appears, as you say, in the 'Shared with me' section. If an account appears in 'Shared with me' there is no option to add the account (or folders within the account, such as the inbox) to the favourites.

Adding shared accounts using an email address and password would be very bad practice as it would mean sharing credentials for accounts (that's a big no for us), and would mean that MFA would have to be disabled on the account. The account would therefore become a significant security risk. The accounts to which our shared mailboxes are attached are all disabled so that they cannot be logged into directly, and sharing is done by means of adding the required users to the mailbox permissions in the M365 console.

Thanks doc-binjuice!

I am using the New Outlook Desktop app.

I hovered over the "Favorites" heading. The three dots appeared. I clicked on them and selected "Add Favorite". I then typed the email address and selected the correct Inbox from the choices. I now have my shared inbox in my favorites area.

That doesn't show the inbox of the shared account - I've just tried it, and it brings up all the sent mails from my own sent items folder which were originally sent to the shared mailbox (I often reply from my own account).

It therefore appears to function as some sort of search filter, including emails in the local account.

My user was able to add shared inbox in Outlook on the Web. She said, " I googled around a bit and added the shared folder manually!"

I guess there is a way to manually add a shared folder manually. After it is visible, you can add it to your Favorites.

Sorry, I don't understand. Only the Inbox shows under Favorites. When I select it, I see all emails that are in the Inbox, the same as the other Inboxes in my Favorites area.
