What is a shared Mailbox?
A shared mailbox is a type of mailbox that multiple users can access to send and receive emails from a common email address (e.g., support@yourcompany.com). It allows teams to collaborate seamlessly without needing separate credentials. Shared mailboxes help streamline communication by centralizing email management, ensuring that important messages are accessible to all relevant team members.
