I am using Zoho Mail within the Zoho One platform. I have completed the basic setup and added all the required DNS records with our domain provider.

Our goal is to set up two-way synchronization between our current Gmail inbox and Zoho Mail, but we are having trouble connecting them. The email address is hosted by our provider, and we have already configured forwarding from the original mailbox.

Could someone please explain what options are available to synchronize all incoming and outgoing emails between Gmail and Zoho Mail (from Gmail to Zoho and from Zoho to Gmail)?
