[Q] Email(MS Exchange 2003) Search & Calendar Tasks list features not available?

[setk]

Am I missing something or is Nexus 7 missing Email(MS Exchange 2003) Search & Calendar Tasks list features?

These features are available on stock SGSIII. Is this a limitation of aosp Email & Calendar, assuming that's what's on the Nexus 7?

If so what are my options to get these features? Do any of the custom roms have these features?

Thanks
