Create Active Directory User with Multiple Email Addresses

In this article, we will learn how to create an active directory user with multiple email addresses. This is useful when you are working in an organization where your clients want to have multiple email addresses for his employees because he wants his employees to send external email messages through an Exchange server.

For this purpose what we need to have is an active directory in windows server. I will use windows server 2012 R2 as an example. First of all log into the windows server using your administrative credentials.

Open the server manager, click on tools and select “Active Directory Users and Computers”

Primary email address must be a valid external email address (not an address which only exists internally). Microsoft Exchange Server permits you to define multiple email addresses for each user in Active Directory, which makes this possible.

In the left side menu, select the OU which contains the users as in this case it is “All Users List”.

Inside this OU I have “All User” OU where I will create a new user with multiple email addresses.

Right-click on “All Users” to select “New” and click on User to create a new user account.

Once New Object – user window console is opened. Enter the required information and click “Next”

Enter the password and press “Next”. In the next window click on finish to finish.

Now right-click on the newly created user and select “Properties”.

Enter the email ID in “E-mail” tab.

Click Apply and then select “Email Addresses” tab. Click the New button and select SMTP Address, then click “Ok”. Enter the email address, for example, user@domain.com and repeat the steps for all the email addresses which you want to associate with one user account.

The mapping between Active Directory (AD) user and Exchange mailbox is one to one. However, various solutions exist that enable users to have multiple email addresses and even have access to separate mailboxes.

If the user just needs different aliases, which, for example, means email can be sent to alpha@usamazaka.local, alphabeta@ usamazaka.local and even alpha.beta@ usamazaka.local, then all that is required is to change the properties of the mailbox and add multiple email addresses using the E-Mail Addresses tab.
