Enterprise cloud email

Challenge: Previously, DOE operated 64 separate email systems, 45 of which were on premises, that serviced 184,387 email addresses. Maintaining multiple on-premise email environments not only drove up agency costs, but increased the enterprise’s threat vector. DOE needed to migrate its email infrastructure to the cloud to provide employees with a more robust email platform, enhance its cybersecurity posture, and reduce IT maintenance costs.

Approach & Outcomes: DOE successfully completed the migration in a single accelerated effort. With TMF support, DOE:

• Moved 14 on-premise systems to cloud email
• Migrated all 15,951 mailboxes to the cloud
• Decommissioned one system
• Established internally-funded migration plans for 12 additional systems
• Identified 2,201 mailboxes that could be decommissioned after eliminating secondary email systems and other inefficiencies

Due to project success and additional internal investment, DOE completed the project with a reduced TMF funding amount.
