Beginning today, you can migrate encrypted emails from other services like Microsoft 365, Microsoft Exchange, or Virtu, to Gmail client-side encryption in the S/MIME format. Specifically:
- S/MIME messages imported from other mail providers are now supported by Gmail CSE
- Virtru customers can use our migration utility to encrypt their plain-text archives from Vault or Takeout, and import them as S/MIME messages
- Customers can bulk-import any plain-text email archives into Gmail as S/MIME messages
Additional details
The Gmail CSE Migration Utility is available for Windows, Mac, and Linux and supports PST & Mbox file formats.
Getting started
- Admins:
- Visit the Help Center to learn more about how to migrate messages to Gmail as client-side encrypted emails.
- Note: For the migration of S/MIME messages from Microsoft 365 or Microsoft Exchange to Gmail, the certificates must be the same as those present in Microsoft.
- You need to set up the Gmail API and Gmail CSE for your users using the same certificates present in the Microsoft service.
