ActiveSync: Migrating existing users to modern Auth

Microsoft is deprecating basic Auth for ActiveSync and as such customers that have currently deployed Forcepoint ONE SSE mobile protection offering for Microsoft 365 will need to migrate their users over to modern Auth.

This guide page will walk you through the process for how to migrate users and what users will see and need to do to switch over.

Note: If you have not setup ActiveSync mobile device protection for your users yet, then you do not need to follow these instruction. Follow the standard instructions for Microsoft 365: Creating a device access rule to enforce cutoff as normal. Users will automatically be using modern authentication once setup.
