How we do Microsoft 365 to Zoho Mail Migration  

We follow a Quickstart Methodology to ensure the migration is secure, compliant, and low-risk:

Step 1 – Discovery / Assessment

We audit your Microsoft 365 tenant (Exchange Online), mailbox sizes, shared mailboxes, groups, retention policies, and third-party integrations to design the migration plan.

Step 2 – Pre-Migration Preparation

• Create user accounts in Zoho Mail (required before migration).
• Verify domain and configure DNS prerequisites (MX/Sender records).
• Ensure required admin access in Microsoft 365 (global/admin or delegated account) and set permissions for migration.

Step 3 – Handle EWS / Throttling Considerations

Exchange Web Services (EWS) throttling in Exchange Online can slow or interrupt migrations. For large migrations, we follow Zoho’s recommendation to request an EWS throttling increase or temporarily disable throttling through the Microsoft 365 Admin Center so the migration runs smoothly. We assist with the required steps and testing.

Step 4 – Backup & Extraction

We take secure backups of your source mailboxes (mail, contacts, calendars) prior to migration to ensure a safety net.

Step 5 – Configuration & Setup in Zoho Mail

We configure Zoho Mail Control Panel for your organization — user roles, groups, email policies, signatures, mailbox quotas, and archiving/eDiscovery settings.

Step 6 – Data Cleaning & Mapping

We review your mailbox data, remove duplicates, standardise contact fields, and map Microsoft 365 folder/label structures to Zoho Mail folders/categories for accurate import.

Step 7 – Data Migration (Pilot + Full Run)

• Run pilot migrations for a subset of users to validate the mapping and mail flow.
• Run full migration in batches, monitor progress from the Zoho Mail Control Panel, and produce migration reports. Zoho’s admin console shows detailed migration reports to help validate success.

Step 8 – Cutover & Verification

Switch MX records (DNS cutover) at your chosen time window, verify inbound/outbound mail flow, and validate data integrity (emails, calendars, shared items).

Step 9 – Training & Handover

Deliver admin and end-user training sessions and hand over detailed runbooks and support documentation.

Step 10 – Post Migration Support

Provide support for any follow-up fixes, mailbox re-mapping, delegation corrections, and performance tuning.
