Zoho Mobile Sync only Calendar (Android)

This is probably not Zoho's fault, but is there a way using exchange sync on Andriod to sync only my calendar and not email. The reason for this is that I have a budget device with very little phone storage space, which quickly gets filled up. I have set do not push mail, but checking frequency can only be set to once per day. There is not option to not check at all. Thanks.
