Hi Amahle, very strange,.it seems that I can send emails from my laptop but unable to send from phones, I have two phones using this email and both have stopped sending. I have changed the password, deleted the account and then reloaded it and tried different apps all to no avail?

Hi there @bhbarton, We apologize for the situation and appreciate your patience as we investigate it. Could you please confirm whether you are unable to send emails to all recipients or if the issue is specific to a certain domain?
