So here is the thing: if we want to include Exchange from other distributions, it brings several dependencies we would also have to include and replace default AOSP packages. This isn't a big thing, but it may generate additional additional workload in future if
a) Those projects or dependencies change and become incompatible with current AOSP.
b) AOSP changes and becomes incompatible with those projects (e.g. major version upgrade).
I don't think we can expect Google to return the Exchange project into AOSP, so here is a question for our community: would you like us to do so and introduce additional dependencies (which might slow down the developments in future) or is it maybe a better idea to make the Exchange package installable (something like https://www.apkmirror.com/apk/google-inc/exchange-services/ or a self-contained app like https://f-droid.org/en/packages/com.fsck.k9/) on the top of emteria.OS?
