Explanation:
Operations Manager also allows you to create custom roles based on the Operator, Read-Only
Operator, Author, and Advanced Operator profiles.
When you create the role, you can further narrow the scope of groups, tasks, and views that the role
can access.
For example, you can create a role entitled “Exchange Operator” and narrow the scope to only
Exchangerelated groups, views, and tasks.
User accounts assigned to this role will only be able to run Operator- level actions on Exchangerelated objects.
Notification Accounts and Groups Individuals in your company that will interact with Operations
Manager frequently, such as an Exchange administrator who has been assigned to the Exchange
Operator role, need a way to discover new alerts.
This can be done by either watching the Operations console for new alerts or by Operations
Manager informing them about the alert via supported communications channels.
Operations Manager supports notifications through e-mail, instant messaging, Short Message
Service, or pager messages.
Notifications on what the role needs to know go out to recipients that you specify in Operations
Manager.
An Operations Manager recipient is merely an object that has a valid address to receive the
notification, such as an SMTP address for e-mail notifications.
Therefore, it is logical to combine role assignment with notification group membership via an emailenabled security group.

For example, create an Exchange Administrators security group and populate it with individuals that
have the knowledge and permissions to fix things in Exchange.
Assign this security group to a custom created Exchange Administrator role so they have access to
the data and are e-mail-enabled.
Then, create a recipient by using the SMTP address of the email- enabled security group.
