Overview of Shared Mailbox

A Shared Mailbox is a special type of mailbox that allows multiple users to access and use it for reading and sending emails. It provides a collaborative email solution, enabling a group of people to work together seamlessly using a single email address. With a Shared Mailbox, team members can efficiently send, view, monitor, and respond to emails in real-time, ensuring rapid communication and quick response rates.

Shared Mailbox

One important aspect of a Shared Mailbox is that when users reply to emails from the mailbox, the sender's email address is that of the Shared Mailbox, not the individual user's. This ensures consistent and uniform communication, as all responses are sent from the same email address, representing the team or department responsible for handling the emails.

Nowadays, more and more users benefit from Mailbox due to mainly the below advantages:

  • Provide a single point of contact for everyone outside the company.
  • Contact lists and shared calendars can be shared.
  • Shared mailboxes reduce clutter and extra storage space as a single mailbox.
  • Promotes cooperation and transparency among members.
  • Reduced duplicate and missed emails.

Things you need to know: Who can Send Messages from a Shared Mailbox?

Shared mailbox delegates have the ability to send emails using permissions like 'send as' or 'send on behalf,' which are assigned to them. However, a challenge arises when a delegate sends an email from the shared mailbox as it gets stored in their personal sent items folder, rather than the shared mailbox's sent items folder. Consequently, other delegates are unable to determine who sent specific replies to emails. To resolve this issue and ensure transparency, administrators can enable specific settings in the shared mailbox, allowing all delegates to view sent emails.
