Group Email Box
Collaborative features are especially useful for technical support or customer service teams.
For example, you can create a group with the address email@example.com, add your support staff as members, and allow people outside your organization to send messages to the group. Your support staff will receive your customers' messages, and they can do any of the following from the group's Topics view:
Assign responsibility for a topic to a member of the group
Mark a topic as resolved
Edit the tags associated with a topic
Filter topics according to tag, resolution status, or assignee
This will allow for a message to be received by all members in a shared mailbox environment. When a user reads a message, the unread tag remains for the other members until they read it. Currently if someone reads a message in the shared mailbox, it shows read for everyone, and no one knows who read it or acted on it.
Lost a client because of this. Google offers this in "Groups For Business"
This is a good idea. It's a shame you lost a client over this. Of course your client traded privacy for a feature. That's something I would never do. Google is evil.
