The caller must be at least a member of role: Customer Administrator

No explicit permission check is required for this procedure. The procedure calls Managed Plans::RemovePlanFromCustomer which tests the caller for the Customer Administrator (UserCreators).

The specified organization was previously subscribed to the service.

The organization cannot be unsubscribed from the service if any users in the organization are enabled for the service.

• The Office Communications Server plan is no longer assigned to the organization.
• The Office Communications Server users plans assigned to the Available Plan list of the organization are removed from that list.
• The SIP Domains which belong to the organization are removed.
• The Office Communications Server Pool assignment for the organization is removed.

1. Actor submits Unsubscribe request to the Hosted Office Communications Server namespace.
2. The Unsubscribe procedure calls the GetOrganizationPlanAssignment procedure, which will retrieve the plan assigned to the organization. This validates that the organization is subscribed to the Office Communications Server service.
3. The Unsubscribe procedure calls Managed Plans::ExecPlanSQL_ to execute the new stored procedure spCountOrgUsersByPlanType. The planTypeName = 'OCSUserHosting'. This will return a count of the users with an active OCSUserHosting plan assignment.
4. Alt: If the count returned by Managed Plans::ExecPlanSQL_ is greater than 0, then an InvalidOperationException (0x80131509) is raised. The exception states that the operation cannot be performed until the users have been deleted with DeleteSipDomain.
5. The Unsubscribe procedure calls the GetOrganizationAvailablePlans. This will return zero or more available plans assigned to the organization.
6. For each availablePlans/planName, the Unsubscribe procedure calls the Managed Plans::SetAvailablePlanStatus with statusTypeName="Deleted".
7. The Unsubscribe procedure calls Managed Plans::RemovePlanFromCustomer with the planName equal to the planName value returned by GetOrganizationPlanAssignment.
8. The Unsubscribe procedure calls Managed Office Communications Server::GetSipDomainsByOrganization. This will return zero or more Sip Domains assigned to the organization.
9. For each sipDomains/sipDomain, the Unsubscribe procedure calls Managed Office Communications Server::DeleteSipDomain if the SIP domain is owned by the organization.
10. The Unsubscribe procedure calls Managed Office Communications Server::DeletePoolAssignment to remove the pool assignment. If there was one it would be deleted if not then it would do nothing.
