A Replacement For Epicenter Servers

Sync Microsoft 365 Global Address Lists to Mobile Devices

No Credit card. No Contract.

An Alternative For Epicenter Customers

On February 19th, Epicenter Services announced the discontinuation of their Epicenter Server. That means customers looking to sync Microsoft 365 Global Address Lists will need to go elsewhere. Unfortunately, Microsoft decided to disable basic authentication, which makes Epicenter Server no longer functional.

For companies looking to migrate their service, or upgrade to Microsoft 365, there’s good news. CiraSync perfectly fills the void left behind by Epicenter Server. What’s more, due to CiraSync’s cloud configuration, the service won’t be interrupted by Microsoft. If you’d like to learn more about CiraSync’s features and pricing, please check here.
