How to remove mails from mail app and maintain google calendar synchronized with Apple Reminders? I've got a gmail account and I use the browser to read, write and manage my gmail account.

I wrongly opened Apple mail and it started synchronizing with gmail.

I would like to maintain google calendar synchronized with Apple Reminders, but I would like to free the space on HD used by Apple mail.

Is it possible?
Try system preferences -> Internet accounts -> uncheck mail from google account
