Office 365 to Proton Migration
Budget: $250 – $750 AUD
I run between six and twenty mailboxes on Office 365 and now need everything—mail, calendars, contacts, and the contents of OneDrive/SharePoint—to live inside Proton Business Suite for stronger privacy and security. The project also involves registering or transferring a fresh domain, configuring DNS, and making sure all messages sent to the old addresses are seamlessly routed to the new Proton accounts until we fully cut over.
Key points you’ll handle
• Email, calendar, and contact migration from Office 365 via IMAP/Exchange protocols (or Proton’s dedicated migration tool, if preferred).
• Secure upload of existing cloud files into Proton Drive with the original folder structure intact.
• Domain setup: MX, SPF, DKIM and DMARC records correctly published so Proton passes all deliverability checks.
• Transparent forwarding or catch-all rules so no message is lost during the transition window.
• Final verification that every user can send/receive, sync calendars, and access all historical data inside Proton’s web, desktop and mobile apps.
Acceptance is simple: once each user signs in to Proton and confirms all legacy data is present, mail flows only through the new domain without bounce-backs, and the DNS tests green-light on mxtoolbox, the job is done.
Let me know your timeline and any questions about the current tenant or the new domain registrar and I’ll provide immediate access.
