Get Procedure to Add a Shared Mailbox in Outlook

A shared mailbox is generally required to get added in the Outlook application for direct sending or receiving messages in an individual folder, thus shedding an extra load of opening it by side.

As we know the shared mailbox can be accessed by a number of users to send and receive emails from the same email address. These user members of the mailbox are assigned permissions from the Microsoft 365 admin to use the shared mailbox and its functionalities.
