Group Emails
Group email folders are shared across designated Teams. Admins can create group email folders and specify which teams have access to a particular folder.
If an email is moved from a group folder to a personal folder or inbox, it will unlink the email from that group folder.
There's the ability to automatically put inbound emails imported through a group email account to a specific group folder. It's also possible move emails matching an email filter to a specific group folder (the filter should be related to a group email account).
Users that have access to a group folder can put there any email (only read level access to the email is required). If an email is located in a group folder the user does not have access to, they won't be able to move that email to another folder.
The field-level-security (in Roles) can be used to restrict the ability to change (edit) the group folder.
