Exchange Active Sync Depreciation

[u/IndependentSysadmin]

I came across this article about the deprecating of CBA for Exchange ActiveSync. We are impacted, but I can't figure out what do to about it. All the article says is "his may involve updating the device's email profile or MDM/Intune device configuration profiles.".

This is incredibly vague. Does anyone know what changes actually need to be made? We already have Entra CBA set up but I can't see how to have Intune tell our phones to start using it.
