I'm running the latest version 115 .. V1 Update 1.
I'm having near 50 users on my system, mostly iPhone / iPad devices.

When adding a new user to the DataSync ...

What is the rule / policy or Work as Design settings for the Initial sync of a user ?

How many days back / emails should be sync to the device ?

How many Calendar items should be sync to the device ?
I know all future events but how many / how long in the Past ?

Can we define / change those settings ???
