Email Security allows you to control which users or security groups can access which email folders. When you create an email folder, it is not accessible from an email list until security rights for that folder have been set up.
Security to view folders is controlled by going to Email > Email Security. You can either add people or security groups to a folder, or a folder to a security group. By default, no one has access to any of the email folders.
As management, you are creating various email folders based on specific areas of your business, then (via Email Security) controlling who is allowed to view these email folders.
You can set email security using the following two methods:
Email Folder by User
This email folder can be viewed by the selected users, or users in the selected security groups. To enable selected users or security groups to view specific email folders, select Email > Email Security in the ribbon. The Email Security screen will open. Select View by and select the Email Folder that you want to allow other people to view. Click Edit and then use the arrow buttons to move users or security groups across to the Selected users/Security Groups panel. When finished, click Save.
User/Security Group by Email Folder
This user/security group can view the selected email folders. To enable which users/security group can view specific email folders select Email > Email Security. The Email Security screen will open. Select View by User/Security Group and select the user or security group that you want to work with. Click Edit and then use the arrow buttons to move Email Folders across to the Selected Email Folders panel. When finished, click Save.
