Amazon WorkMail has confirmed the end-of-life of Amazon WorkMail. It will stop taking new registrations from April 2026, and full service shutdown scheduled for March 2027. After all, the organization is required to change their productive tool. This announcement has pushed many businesses to rethink their email infrastructure and move toward more established, feature-rich platforms.
Organizations are shifting to Office 365 mainly for its stronger collaboration tools, wider third-party integrations, better scalability, and long-term reliability compared to WorkMail's limited ecosystem. With the shutdown deadline approaching, planning a smooth transition has become essential rather than optional.
This is where the Shoviv Amazon WorkMail to Office 365 Migration Software becomes valuable. It is designed to transfer emails, contacts, calendars, and attachments accurately, without relying on complex manual scripting or AWS-specific technical expertise. The tool supports batch migration, maintains folder structure, and offers a straightforward interface suited for both administrators and IT teams.
For businesses aiming to avoid last-minute data loss, starting the migration early using a dependable tool like Shoviv can make the entire process smoother, safer, and far less stressful before the final shutdown date arrives.

To migrate Amazon WorkMail to Office 365 in 2026, the most practical approach is an IMAP-to-IMAP migration, since WorkMail and Microsoft 365 can communicate through IMAP. For a small mailbox, you can configure both accounts in an email client and move the folders manually, but this becomes time-consuming when multiple mailboxes or large email archives are involved. You also need to watch folder mapping, attachments, and synchronization.

For a larger migration, I’d use a cloud migration utility that connects the Amazon WorkMail source account with the Office 365 destination mailbox. GainTools Cloud Migration Software supports IMAP-to-IMAP migration, selective folder transfer, date-based filtering, and migration of emails and attachments while retaining folder structure and email properties.

The basic workflow is: add the WorkMail server and account details → enter the Office 365 destination details → select source folders → apply filters if required → start migration. The migration tool’s documentation also notes that the correct login details for both accounts are required.

For a business migration, I’d first test one mailbox and verify folders, attachments, and recent emails in Office 365 before moving the remaining accounts.
