Email Migration Support for Every Scenario

Exchange On-Premises to Microsoft 365

Moving off a local Exchange server is one of the most common — and most complex — migrations an IT team undertakes. Affirma handles assessment, planning, mailbox migration, DNS cutover, and post-migration validation.

Exchange Hybrid to Exchange Online

Already in a hybrid environment? We help you complete the transition to fully cloud-hosted Exchange Online, cleaning up your on-prem footprint and ensuring all routing, policies, and configurations carry over.

Third-Party Email to Microsoft 365

Migrating from Gmail, Lotus Notes, GroupWise, or another platform? We map your current environment to M365, migrate all mailbox content, and configure Teams, SharePoint, and OneDrive to match the way your team works.

Tenant-to-Tenant Migration

Mergers, acquisitions, divestitures — when one Microsoft tenant needs to merge into another, Affirma manages the full migration of users, mailboxes, groups, and shared resources across both environments.

"As a small IT shop, we reached out to Affirma for assistance on how we could gain more value from our Office 365 services. We have been able to fully take advantage of the amazing services that Office 365 has to offer, dramatically increasing our internal communications while further securing our environment."

"Security of our files is very important to us. Affirma helped us migrate our files from our local server to Microsoft SharePoint. The migration went very smoothly, and the adoption of SharePoint by our staff was quick. Affirma helped us through every step of the project."

Email Migrations Are Harder Than They Look

Most organizations underestimate what a migration involves — until they're in the middle of one. Mailbox data, calendar items, shared inboxes, distribution groups, archive folders, permissions, and mobile device policies all need to move correctly. And your team needs to stay productive the entire time.

Common problems we help you avoid:

  • Mailbox data that doesn't migrate cleanly

  • Downtime during cutover that disrupts operations

  • Missing or corrupted calendar and contact records

  • Coexistence failures when running hybrid environments

  • Employees locked out of email during transition

  • Compliance gaps when migrating regulated data
