This guide will help you Integrate Silverback into a Microsoft Exchange environment using PowerShell. This allows you to control who can access Exchange ActiveSync from Smartphones and Tablets. Silverback acts as the management platform providing control over Exchange ActiveSync access based on its policies. Silverback will either allow managed devices, or deny unmanaged devices, ensuring a base level of compliance. This is the simplest Exchange ActiveSync control mechanism, and the quickest to implement. Safely interconnect your EAS server with our Matrix42 Silverback solution by using Powershell. Put your EAS Server into quarantine mode to only allow whitelisted devices access. Matrix42 Silverback will whitelist all managed devices on the EAS server. Non-managed device will not get access to the EAS server.
