Shared mailboxes make it easy for a specific group of people to monitor and send email from a common account, such as email@example.com or firstname.lastname@example.org. When a person in the group replies to a message sent to the shared mailbox, the email appears to be sent from the shared mailbox, not from the individual user.
You can configure the shared mailbox with the following delegate permissions:
- Full Access The Full Access permission
allows a user to log into the shared mailbox and act as the owner
of that mailbox. While logged in, the user can create calendar
items; read, view, delete, and modify email messages; create tasks
and calendar contacts. However, a delegate with Full Access
permission can’t send email from the shared mailbox unless they
also have Send As or Send on Behalf permission.
- Send As The Send As permission allows a
user to impersonate the shared mailbox when sending mail. For
example, if Kweku logs into the shared mailbox Marketing Department
and sends an email, it will appear as though the Marketing
Department has sent the email.
- Send on Behalf The Send on Behalf
permission allows a user to send email on behalf of the shared
mailbox. For example, if John logs into the shared mailbox
Reception Building 32 and sends an email, it will appear to
recipients as being sent by “John on behalf of Reception Building
32”. To grant Send on Behalf permissions, you must use the Exchange
Management Shell. Use the Set-Mailbox cmdlet with the
