Customers are often in a misconception that the pre-requisite condition for a customer to create a Gmail calendar account is to have a valid and active Gmail account. In case the users do not posses any Gmail account, he can choose to create a Gmail account using any Gmail account (which may even be his business Gmail), and then link the same to calendar. The Gmail calendar can be configured and customized as per the requirement of the user. And, all the processes are performed without any intervention of a mobile app. Customers can also seek the guidance of Gmail Customer Support team for any issues faced while creating calendars using any Gmail address.
