Deployment readiness &security

Set up your Microsoft 365 tenant properly and examine how the tool processes,stores,and transfers data.

Office 365 preparation (before migration)

For your destination tenant,follow the given steps before starting conversion:

  • Admin access:Take help of a Global Administrator or delegated role to access MS365 without blocking tenant consent.
  • Target mailboxes:Verify each Office 365 / Exchange Online mailbox and assign a valid Microsoft 365 license before conversion starts.
  • Source IMAP with 2FA:For IMAP platforms using two-factor authentication,generate an app password.
  • Azure app registration (optional):Follow the security team guidelines if enterprises register with Azure AD for OAuth consent.
  • Pilot run:Before doing the full mail migration,test the software on one mailbox first.

Data security &compliance

Designed to build trust signals not marketing claims:

  • Zero data retention:Credentials and mailbox content are safe,not stored in Softaken servers. Conversion processes at your local Windows machine.
  • Modern authentication (OAuth 2.0):For destination sign-in,advanced data security is supported with WebView2 OAuth flow to retain Microsoft 365 admin password privacy.
  • Copy-only workflow:Only copy the IMAP mails instead of deleting data after conversion.
  • Audit reports:Check the HTML/CSV reports for IT change-management records and client approval.
