Amazon WorkMail End of Life: Back Up and Migrate Before the Shutdown
Amazon WorkMail users have an important deadline. AWS made an official announcement that the end of support for Amazon WorkMail is scheduled for March 31, 2027. As of that date, users will no longer be able to access WorkMail, including the WorkMail console and resources. New Amazon WorkMail customers will not be able to register from April 30, 2026.
If your organization uses Amazon WorkMail as an email provider for your business communications, calendar, and contact management, now is the right time to consider how to manage your mailboxes and archived email messages.

In this post, we’ll discuss Amazon WorkMail end of life, important dates, consequences of WorkMail shutdown, how to migrate Amazon WorkMail before shutdown, and the steps you can take to prepare for WorkMail shutdown.

What is Amazon WorkMail End of Life? Official Timeline
Amazon WorkMail is the AWS-managed business email and calendar service that operates via Microsoft Outlook, web browsers, and native mail applications for iOS and Android and gives the ability to admin control of encryption keys and location of stored information.
In March 2026, AWS announced an end-of-life notice in the official WorkMail Administrator Guide. Important dates are as follows:
- April 30, 2026: WorkMail stopped accepting any new accounts. Accounts that existed before this date will continue to work.
- Until March 31, 2027: Current users may continue to use WorkMail functionality. This is your migration time window.
- March 31, 2027 and after: End of support period. You cannot use WorkMail services, console, or any of its resources anymore.
It is not a feature freeze or “maintenance mode”. The service itself will be shut down. Any mailbox data that has not been migrated or backed up before the deadline might become inaccessible after WorkMail is discontinued.
What Happens After Amazon WorkMail?
Following the discontinuation of Amazon WorkMail, you will face several issues other than “no more support tickets.” Here are some of them:
- No mailbox: There will be no access to the mailbox via Outlook, the web application, or any mobile device.
- No Admin Console: Resetting passwords, exporting mailboxes, and making any other changes to the mailboxes will be impossible.
- Broken Mail Flow: If the domain’s MX records are still pointing to WorkMail, incoming emails will no longer be delivered to the recipients.
- Calendar and History gone: All meetings, calendars, and emails of the past years will become inaccessible.
- Integrations are broken: Lambda rules, journaling, and directory integrations will cease working.
The worst part about that situation is not the shutdown itself but the realisation that you will lose your archive after the deadline.
Why Is AWS Shutting Down WorkMail?
As per AWS, it has decided to discontinue support for Amazon WorkMail after careful consideration. There has been no official business reason given by the company for this decision. However, for all current users of this service, the main question is the timeline for migration.
Users need to use the time available to find another service provider and migrate to it before the deadline of March 31, 2027.
