Test and enable after enabling tasks/appointments sync for mailbox

Hi!

I have mailboxes that have been approved , tested enabled and working with incoming and outgoing as server side sync.

My question is if i then enable Appointments, contacts and task by switching it from dynamics for outlook to server side sync, would i need to test and enable the mailbox again to get it working. I would like to avoid that test email that goes out to the users if possible

Thanks in advance
