📥 What Is a Shared Mailbox?
A Shared Mailbox is a mailbox that one or more users can access to read and send email messages on behalf of a supplemental or group account. It also includes a shared calendar, making it easy for teams to coordinate schedules and manage events. S These mailboxes are ideal for departments, student organizations, or project teams.
Key Features:
- Collaborative Email Management: Multiple users can send and receive emails from a shared address (e.g.,
its@stcloudstate.edu
).
- Unified Identity: Replies sent from the shared mailbox appear to come from the shared address, not from individual users.
- Shared Calendar: Teams can use the mailbox’s calendar to schedule and view meetings or events.
- No Direct Login: Shared mailboxes are not designed for direct sign-in. Access is granted through your primary account.
⚠️ Note: Most Shared mailboxes are not designed for direct sign-in. Access is granted through your primary account.
