What it is

Handles all aspects of starting, maintaining, and stopping the various sync adapters for the email accounts.

Is it only needed for the email stock app?

Commands

adb shell pm uninstall --user 0 com.android.exchange

To put it back:

adb shell cmd package install-existing com.android.exchange

Every removal listed here is per-user only: the system image is untouched, and the restore command puts the app back from the copy already on the device. Nothing is downloaded.

This is not the directory. Here we say what a package is in general; what happens on your particular television is on your model's entry, and that one wins. The same package can be dead weight on one set and hold the home screen up on another.
