We have been trying to log in to my son's email to clear out old messages still on the server. Accessing it via an email program or on his phone works fine. But logging in through the webmail portal brings up an error every time saying that the information does not match. I then tried logging in to my husband's email and same thing happened. Same thing with my person email account. and our main account. I clear all my emails off the server from our mail program but my son and husband do not. How can I clear the 700+ emails off the server for his account if I cannot log in???
