The policy described in this scenario allows multiple stores to be used for mailbox creation, and forces Active Roles to automatically select the store that holds the least amount of mailboxes.
To implement this scenario, you must perform the following actions:
As a result, when creating a mailbox for a user account that resides in the container you selected in Step 2, Active Roles chooses the least loaded store among those where mailbox creation is allowed.
The following two sections elaborate on the steps to implement this scenario.
You can create and configure the Policy Object you need by using the New Provisioning Policy Object wizard. For information about the wizard, see Creating a Policy Object in the Policy Object management tasks section earlier in this chapter.
To configure the policy, click Exchange Mailbox AutoProvisioning on the Select Policy Type page of the wizard. Then, click Next.
On the Allowed Mailbox Stores page, select the stores in which you want mailbox creation to be allowed. Then, under Pick a store, click Containing the least number of mailboxes, as shown in the following figure.
Figure 58: Allowed mailbox stores
Click Next, and follow the instructions in the wizard to create the Policy Object.
You can apply the Policy Object by using the Enforce Policy page in the New Provisioning Policy Object wizard, or you can complete the wizard and then use the Enforce Policy command on the domain, OU, or Managed Unit where you want to apply the policy.
In the wizard for creating user accounts, whether in the Active Roles console or Web Interface, the Create an Exchange mailbox option is selected by default, causing the user mailbox to be created upon creation of a user account. This behavior can be changed by applying an appropriately crafted policy of the Exchange Mailbox AutoProvisioning category.
A policy can be configured so that the Create an Exchange mailbox option is not selected by default but the administrator who uses the wizard to create a user account can select that option if necessary. It is also possible to configure a policy that forces the Create an Exchange mailbox option to be selected.
