Unified Messaging Users

There is actually not an Active Directory object for unified messaging users. Rather, the unified messaging properties are stored in the Active Directory user account and the Exchange 2010 mailbox. Voicemail messages and fax mail messages are stored in the user’s mailbox.

These properties can be found in the Exchange Management Console in the properties of the user’s account in the Recipient Configuration, Mailbox folder. Within the user account properties, the unified messaging settings are under the Mailbox Features tab in the properties of the Unified Messaging feature. After navigating to the Unified Messaging feature, click the properties button to access the feature properties.

When enabling a user for unified messaging, the associated UM mailbox policy and extension must be specified. The link to the mailbox policy provides a one-to-one link to the UM dial plan.

The user’s mailbox quotas apply to both voicemail messages and fax messages. If the user’s quota settings prevent the user from receiving email (for example, the user’s mailbox is full), unified messaging functionality will be affected. Callers attempting to leave a message will not be allowed to do so and will be informed that the user’s mailbox is full.

Exchange 2010 unified messaging includes several features to control the size of voicemail messages to help control the storage impacts.
