I use Gmail myself. E-mail on the MaxiSYS functions OK, but calendar won't sync with Google servers due to our units not being approved devices by Google. I assume that tech support/Autel just needs to submit the units for approval, then all should be good. We would then get access to Google play store as well. Other than this issue, I don't really have any complaints on the MaxiSYS, hell of a money maker for me.
