By default Exchange server has one email address policy for all mail enabled objects in active directory. These mail enabled objects include mailbox, Contacts, resource mailbox etc. Exchange server delivers emails to these email address in a domain.
The purpose of creating an email address policy is to accept emails for multiple domains. The mail enabled AD object will have multiple email address if we apply multiple email policies to that AD object. But only one email address can be reply address. Before we create an email address policy we need to add accepted domains for which our exchange server will accept emails.
There are 3 ways we can add accepted domains
- Authoritative domains
- Internal Relay domains
- External Relay domains
Authoritative domains means the email sent to this domain will be delivered to recipients in that exchange organization
Internal Relay domain means the email sent to that domain will be delivered to the recipients in that exchange organization and also relayed to an external server outside the organization.
External Relay domain means the email sent to that domain will be relayed directly to a server outside the exchange organization
We can use Exchange Admin Center to create email address policy in Exchange Server 2013
- Navigate to Mail flow > Email address policies, and then click Add .
- In Email Address Policy, complete the following fields:
- Policy name
- Email address format
- Specify the types of recipients this email address will apply to
- Click Add a rule to further restrict the recipients that this policy will apply to. This creates a Boolean And statement.
- Click Preview recipients the policy applies to to view the recipients that policy will apply to.
- Click Save to save your changes and create the policy.
- You’ll get a warning that the email address policy won’t be applied until you update it. After it’s created, select it, and then, in the details pane, click Apply.
So we have created an email address policy for mail enabled users in exchange Server 2013
