Update Email: This helps users change their connected email ID to another without disconnecting the previous connection.
New outbound emails from the CRM will start syncing with the newly added email address. Upcoming messages in the previously connected email ID (same thread) will stop syncing between the CRM & personal email.
Disconnect Email: This helps users to disconnect their connection and stop the sync with the CRM. Post disconnect, emails or messages will not sync between both platforms.
