You can select users and groups from native and LDAP security domains. The Developer tool displays selected users and groups using the following format:

When you configure a user to receive an email notification, the Notification task sends an email to the user at the email address that the user account properties specify. When you configure a group to receive an email notification, the Notification task sends an email to all users in the group at the email addresses that the user account properties specify.

If a user account email address is not valid, the Notification task runs and reports back to the domain that the email address is undeliverable. The Notification task sends an email to the address that the Email Service specifies to indicate the delivery failure.

You can use the Administrator tool to enter an email address for native user accounts. You cannot use the Administrator tool to enter an email address for LDAP user accounts. If the user account information imported from the LDAP directory service includes an email address, the Notification task can send an email to the user at that email address.

You can select a recipient multiple times by selecting a user and then selecting a group that the user belongs to. When the Notification task sends the email, the duplicated recipient receives multiple emails or a single email based on how the email server handles duplicate recipients.

When you configure the email properties for a Notification task, you can enter user and group names in the address fields and configure dynamic recipients. Dynamic recipients are users and groups that you define in workflow parameters or variables.
