What is a group mailbox?

A group mailbox is a shared inbox accessible by multiple users, allowing team collaboration under one address. In some setups, messages sent to this address can be distributed or copied to multiple team members automatically.

While this setup improves visibility and collaboration, it also introduces challenges like duplicate responses, missed ownership, or privacy concerns if sensitive mail is forwarded too broadly.

Imagine a shared captain's cabin where several officers can read and respond to the same messages, and where every officer must coordinate to avoid sending two replies to the same passenger.
