Proton Easy Switch helps firms move from Microsoft 365 in days

Proton has introduced Easy Switch for Business, a tool aimed at moving specific data from Microsoft 365 to Proton Workspace in a shorter time frame. The tool focuses on transferring emails, contacts, and calendars rather than the entire Microsoft 365 environment. This explainer breaks down what changed, who is affected, and practical steps for organizations considering the switch.

What changed in migration ease

Historically, migrating from Microsoft 365 to another system could take several months because administrators had to inventory data, export messages, and manually re-create or re-point many elements. Proton Easy Switch streamlines a repetitive portion of that process by automatically transferring emails, contacts, and calendar data from a cloud-based Microsoft 365 setup to Proton Workspace. It does not move all data or settings (for example, SharePoint files, OneDrive, policy configurations, Teams, or the full tenant setup). The key point is that the migration is faster for a defined subset of data, not a complete replacement of the entire Microsoft 365 environment.

Key facts you should know

Who is affected: IT administrators who manage corporate, cloud-based Microsoft 365 environments and plan a data switch to Proton Workspace. The tool targets migration tasks that are repetitive, reducing manual workload for staff. What is moved: Emails, contacts, and calendar data. What is not moved: SharePoint and OneDrive files, business applications, Intune policies, Teams configurations, or the full tenant setup. Time frame: The aim is a migration completed in a matter of days for the covered data subset, not a full system replacement. Language in Proton’s description emphasizes this as a partial, automated transfer rather than a complete shutdown of Microsoft 365 services.

Who is affected

Organizations currently using Microsoft 365 in the cloud who want to move a defined portion of data to Proton Workspace can potentially benefit. IT leaders should assess whether their migration scope matches the tool’s capabilities (emails, contacts, calendars) and whether remaining components (documents, apps, policies) will stay in Microsoft 365 or be handled separately. End users are not required to manually export their data, but they should be informed about what will be transferred and what will stay behind.

Practical next steps

1) Define scope: Confirm which data types to migrate (emails, contacts, calendars) and list what will not be moved (SharePoint, OneDrive, Teams, policies). 2) Engage IT stakeholders: Coordinate with security, compliance, and operations to ensure data handling aligns with policy requirements. 3) Plan timing: Schedule migration windows that minimize business disruption. 4) Prepare for post-move tasks: Verify data integrity in Proton Workspace, update access permissions, and re-establish essential workflows. 5) Communicate with users: Provide clear expectations about what is transferred and what remains, and offer support during the transition.

Limits and questions

Limitations described by Proton emphasize that the tool does not relocate the entire Microsoft 365 environment. Organizations should confirm how any remaining Microsoft 365 components will be managed and whether additional tools are needed for a full migration later. Questions to ask include: Can the remaining data be migrated in a separate step if needed? What are the security implications of moving emails and calendars to Proton Workspace? How will ongoing collaboration features (like Teams) be replaced or reconfigured if needed?
