Amazon WorkMail quotas
Amazon WorkMail can be used by enterprise customers as well as small business owners. Although we support most use cases without the need to configure any changes in quotas, we also protect our users and the internet against abuse of the product. Therefore, some customers may run into quotas that we have set. This section describes these quotas and how to change them.
Some quota values can be changed, and some are hard quotas that cannot be changed. For more information about requesting a quota increase, see AWS Service quotas in the Amazon Web Services General Reference.
Amazon WorkMail organization and user quotas
You can add up to 25 users to your Amazon WorkMail organization for a 30-day free trial. After this period ends, you are charged for all active users unless you remove them or close your Amazon WorkMail account.
All messages that are sent to another user are considered when evaluating these quotas. These include emails, meeting requests, meeting responses, task requests, and messages that are forwarded or redirected automatically as the result of a rule.
When requesting a quota increase for only a specific organization, include the organization name in your request.
