PIN can be reset on a Unified Messaging (UM)-enabled mailbox for a user outside a scoped OU


View products that this article applies to.

Symptoms

In a Microsoft Exchange Server 2016 environment, consider the following scenario:

  • You create a Role Based Access Control (RBAC) management role by adding certain management role entries that are based on the Unified Messaging (UM) Mailboxes role, such as the Set-UMMailboxPIN cmdlet.
  • You create a management scope by using a recipient restriction filter and specify a particular organizational unit (OU) to the filter.

  • You create a management role group that has this management role and management scope assigned.

In this scenario, when admin members in the management role group run the Set-UMMailboxPIN cmdlet, they can reset the PINs on the UM-enabled mailboxes for users who are outside the scoped OU.
