This article was developed to describe how to establish access to "Shared User Data" within the CRM. Shared User Data is a setting that allows Users you are editing to gain access to contacts that are assigned to other Users.
To begin, log in to the CRM, click the Admin tab, and then click the white arrow 
to the right of the User you wish to edit.
On the Edit User page that appears, scroll down to the bottom of the page to the "Shared User Data" section (see below). This is where the users whose contacts are visible to the user you are editing.
NOTE: Select "--Everyone--" to have access to all contacts, regardless of user.
Examples
Below are two scenarios that describe the steps to follow to enable the sharing of user data:
Scenario #1
"I want our president/owner to have access to all contacts"
1. Locate the president/owner's User from the Admin tab, then click to edit.
2. In the Shared User Data box, select --Everyone--.
3. Click Save User.
For changes to take effect, the owner/CEO User must log out of the CRM.
Scenario #2
"I want our Sales Manager to have access to all contacts assigned to Sales Users."
1. Locate the Sales Manager's User from the Admin tab, then click to edit.
2. In the Shared User Data box, select each Sales User (Ctrl + left click to highlight multiple).
3. Click Save User.
For changes to take effect, the Sales Manager User must log out of the CRM.
NOTE: This feature can be used when re-assigning contacts or creating contact lists based on a specific user's data.
