These mailboxes are important when several members of a team require access to the same information. The contents might be anything from a support email address to a reception desk or any other company-related information. Multiple persons having permission by the admin can access and share this information.
The individuals that establish and manage these shared email accounts are the admins.

Method 3: Shared Mailbox Conversion and Migration
Some companies might have deployed hybrid Microsoft 365 or have performed an on-premises Exchange Server to Exchange Online migration. They may choose to keep the settings of the on-premises infrastructure on the cloud as well.
To keep the content and mailbox properties, organizations may need to execute directory synchronization. Although normal mailboxes may be converted into shared mailboxes later, it is preferable to do so in the existing environment.
This should be done before synchronizing with the new tenant to prevent technical difficulties with write-back characteristics.
This technique, however, requires much more planning and preparation on the part of the end-users.
