Cambodia Airports Migrate their Email to Office 365


Cambodia Airports project was officially closed with 369 users migrated from Lotus Notes to Office 365 in Phnom Penh, Siem Reap and Sihanouk International Airports. It was a well synchronized work of Cambodian, Malaysian and Russian teams.

Cambodia Airports holds the concession for the development and the management of Cambodia’s three international airports serving its main economic poles and tourist destinations: the capital city of Phnom Penh; Siem Reap, home to the UNESCO World Heritage Angkor Archeological Park; and the port city and resort town of Sihanoukville.

Office 365 has been selected as a replacement for the current email infrastructure based on Lotus Domino. Microsoft solution was intended to solve the following issues:

  • Outdated Lotus Notes software didn’t respond to current business requirements
  • Upgrades required significant investments
  • Lotus Notes required costly maintenance (storage, server power, licenses, technical staff)
  • The need to provide SLA 99.9% scheduled uptime

After a pre-deployment phase which included formalizing requirements, deployment design and architecture was completed, the project team deployed a cloud infrastructure intended to coexist with on-premise infrastructure.

The next phase was end user training at the dedicated Office 365 End Users Awareness WorkShop followed by migration of users’ mailboxes from Lotus Domino to Microsoft Exchange Online. At the final phase the project team developed all the necessary documentation. In this project the team had to resolve multiple challenges.

100% users mailboxes has been migrated in O365, and deployed Directory Service synchronization service with the cloud can be used in next projects to synchronize all airports operated by the group of companies. Training has been performed for 292 employees. The project was completed 1 month ahead of schedule.
