Frequently Asked Questions

How long does an Exchange to Microsoft 365 migration take?

Migration timelines vary by organization size and complexity. Small organizations (under 500 users) typically complete in 2-4 weeks. Mid-size (500-5,000 users) takes 1-3 months. Enterprise migrations (5,000+ users) require 3-6 months with phased rollouts to minimize disruption.

Can we maintain a hybrid Exchange environment?

Yes, hybrid Exchange deployments allow you to maintain on-premises Exchange servers while using Exchange Online. This provides flexibility for compliance requirements, gradual migration, and specific workloads that must remain on-premises.

What happens to our email data during migration?

All email, calendar, contacts, and archive data are migrated with full fidelity. We use Microsoft-native tools and proven methodologies to ensure zero data loss. Users maintain continuous email access throughout the migration process.

Is Exchange Online HIPAA compliant?

Yes, Exchange Online (Microsoft 365) is HIPAA compliant when properly configured with a Business Associate Agreement (BAA). EPC Group specializes in healthcare compliance and ensures proper encryption, DLP policies, and audit logging are configured.

What is the cost of Exchange Online licensing?

Exchange Online Plan 1 starts at $4/user/month. Exchange Online Plan 2 with archiving and eDiscovery is $8/user/month. Most enterprises choose Microsoft 365 E3 ($36/user/month) or E5 ($57/user/month) for complete productivity suites.
