# CreateOrganization
**Important**
End of support notice: On March 31, 2027, AWS will end support for Amazon WorkMail. After March 31, 2027, you will no longer be able to access the WorkMail console or WorkMail resources. For more information, see [Amazon WorkMail end of support](https://docs.aws.amazon.com/workmail/latest/adminguide/workmail-end-of-support.html).
Creates a new WorkMail organization. Optionally, you can choose to associate an existing AWS Directory Service directory with your organization. If an AWS Directory Service directory ID is specified, the organization alias must match the directory alias. If you choose not to associate an existing directory with your organization, then we create a new WorkMail directory for you. For more information, see [Adding an organization](https://docs.aws.amazon.com/workmail/latest/adminguide/add_new_organization.html) in the *WorkMail Administrator Guide*.
You can associate multiple email domains with an organization, then choose your default email domain from the WorkMail console. You can also associate a domain that is managed in an Amazon Route 53 public hosted zone. For more information, see [Adding a domain](https://docs.aws.amazon.com/workmail/latest/adminguide/add_domain.html) and [Choosing the default domain](https://docs.aws.amazon.com/workmail/latest/adminguide/default_domain.html) in the *WorkMail Administrator Guide*.
Optionally, you can use a customer managed key from AWS Key Management Service (AWS KMS) to encrypt email for your organization. If you don't associate an AWS KMS key, WorkMail creates a default, AWS managed key for you.
