Add a shared mailbox to Outlook for Mac, Outlook on the Web, and on your phone
Shared mailboxes are usually generic email accounts which are accessed by more than one person, typically something like firstname.lastname@example.org or email@example.com.
They can also be mailboxes belonging to someone else to which you have delegated access. This might be your manager’s email account, for example.
Shared mailboxes appear automatically in Outlook on Windows, but need to be manually added to Outlook for Mac, Outlook on the web and on your phone. Only the Outlook app on phones and iPads support adding shared mailboxes, so if you haven’t already, you’ll need to be using that app for your work email. See here for Apple devices and here for Android phones.

On the Tools menu, click Accounts > Advanced then click the Delegates tab.
Under Open these additional mailboxes click the + symbol and enter the email address of the shared mailbox, followed by Add and OK.
