A financial holdings group has multiple locations around the world and has been using IBM Lotus Notes mail systems for many years. Due to the Group's scattered workforce, complex network architecture, large annual licensing and maintenance costs, and the overwhelming trend of collaboration in recent years, Acer AEB recommends Microsoft Exchange Server, which can lower the costs and enable businesses to make significant strides toward digital transformation.
The project spans 3 subsidiaries, 3 countries, nearly 20 mail servers and nearly 7000 staff. It not only operates in different countries and integrates email routings across different domains, but also achieves the difficult task of integrating the address books of different subsidiary companies.
Acer AEB helped the customer to plan the following aspects of the project:
Migrate Notes mail, calendar, to-do list and address book to Exchange
Maintain normal mail services during system conversion
Deliver mail between companies (in the same domain)
Synchronize address books for all companies
Create a high availability architecture for the email platform
Create a disaster recovery mechanism for the mail system

1. Lotus upgrade and maintenance costs cut: Annual costs reduced by approximately 22–35%.
2. Complete integration of the Group's address books to make management easier.
3. Establishing the collaboration platform to lay the foundation for digital transformation.
