Amazon WorkMail concepts

The terminology and concepts that are central to your understanding and use of Amazon WorkMail are described below.


A tenant setup for Amazon WorkMail.


A globally unique name to identify your organization. The alias is used to access the Amazon WorkMail web application (https://alias.awsapps.com/mail).


The web address that comes after the @ symbol in an email address. You can add a domain that receives mail and delivers it to mailboxes in your organization.

Test mail domain

A domain is automatically configured during setup that can be used for testing Amazon WorkMail. The test mail domain is alias.awsapps.com and is used as the default domain if you don't configure your own domain. The test mail domain is subject to different limits. For more information, see Amazon WorkMail quotas.


An AWS Simple AD, AWS Managed AD, or AD Connector created in AWS Directory Service. If you create an organization using the Amazon WorkMail Quick setup, we create a WorkMail directory for you. You can't view a WorkMail directory in AWS Directory Service.


A user created in the AWS Directory Service. The user can be created in an USER or REMOTE_USER role. When a user is created and enabled with an USER role, they receive their own mailbox to access. When a user is disabled, they can't access Amazon WorkMail.

User created and enabled with a REMOTE_USER role is listed in the address book but do not get a mailbox in Amazon WorkMail. The REMOTE_USER can have the mailbox hosted outside Amazon WorkMail but will still be listed as any other user with mailbox in the Amazon WorkMail address book and can look up each others calendar to find free or busy information.


A group used in AWS Directory Service. A group can be used as a distribution list or a security group in Amazon WorkMail. Groups don't have their own mailboxes.


A resource represents a meeting room or equipment resource that can be booked by Amazon WorkMail users.

Mobile device policy

Various IT policy rules that control the security features and behavior of a mobile device.

The following services are used along with Amazon WorkMail:

  • AWS Directory Service—You can integrate Amazon WorkMail with an existing AWS Simple AD, AWS Managed AD, or AD Connector. Create a directory in the AWS Directory Service and then enable Amazon WorkMail for this directory. After you've configured this integration, you can choose which users you would like to enable for Amazon WorkMail from a list of users in your existing directory, and users can log in using their existing Active Directory credentials. For more information, see AWS Directory Service Administration Guide.

  • Amazon Simple Email Service—Amazon WorkMail uses Amazon SES to send all outgoing email. The test mail domain and your domains are available for management in the Amazon SES console. There is no cost for outgoing email sent from Amazon WorkMail. For more information, see Amazon Simple Email Service Developer Guide.

  • AWS Identity and Access Management—The AWS Management Console requires your user name and password so that any service you use can determine whether you have permission to access its resources. We recommend that you avoid using AWS account credentials to access AWS because AWS account credentials can't be revoked or limited in any way. Instead, we recommend that you create an IAM user and add the user to an IAM group with administrative permissions. You can then access the console using the IAM user credentials.

    If you signed up for AWS but have not created an IAM user for yourself, you can create one using the IAM console. For more information, see Create individual IAM users in the IAM User Guide.

  • AWS Key Management Service—Amazon WorkMail is integrated with AWS KMS for encryption of customer data. Key management can be performed from the AWS KMS console. For more information, see What is the AWS Key Management Service in the AWS Key Management Service Developer Guide.
