EXCHANGE SERVER 2010 EMAIL ADDRESS POLICIES- Part-1



E-mail address policies which were known as Recipient Policies back in Exchange 2000/2003, define the proxy addresses that are stamped onto recipients in the Exchange 2010 organization. Email policies are added on an organization level meaning they apply to the whole Exchange 2010 organization, with Exchange 2010 the recipient policies have been split in two; Accepted Domains and E-mail address policies.


Any Exchange 2010 organization will have one email address policy named “Default Policy”. You can view this in the Exchange Management Console under Organization Configuration -> Hub Transport, in the Email Address Policies tab.

Exchange 2010's default email address policy
The first thing we’ll notice that the default policy is not scoped to any particular recipient container, so it will apply to any object in Active Directory. The other thing you’ll notice is that the policy will apply to “All recipient types”, not a limited subset of the available types such as mailboxes, contacts, or groups.

Scope of the default email address policy in Exchange 2010
At the next dialog we will get a chance to preview the results of the conditions in the email address policy.

Previewing the results of email address policy conditions
If we preview the default email address policy we should see all mail-enabled objects in the organization returned.

At the next dialog we’ll see the email addresses that the policy will apply to those recipients that fall within the scope of the policy.

Email addresses applied by the default email address policy
So the outcome of this policy is that it will apply an email address of alias@tech.com to any recipient type.


But when does the email address policy apply? At the next dialog we can see the schedule options for the email address policy.


Email address policy schedule options
The options we can choose from are:
  • Do not apply – The email address policy will be created (or edited) but not applied to the recipients that fall within its scope
  • Immediately – The email address policy will be applied immediately to the recipients that fall within its scope
  • At the following time – The email address policy will be applied at the nominated time. This is convenient if we are preparing the email address policy in advance of a scheduled change.
Something we need to be aware of is that no matter which of the above options you pick right now, the email address policy will continue to be assessed and applied to recipients on an ongoing basis in the future each time a recipient is created or modified.
So for example when a new mailbox is created the email address policies are assessed and applied accordingly. Similarly, if we modify an existing mailbox user, for example to change their alias or move it to another database, the email address policies will be reassessed for that recipient.
For that reason we want to be sure that any email address policy that exists in your organization is ready to be applied to recipients.
