In Outlook I was putting in all my email addresses and doing them through POP3 (which I prefer). When I put in my Incoming and Outgoing Server names I then saved them and when I went back in to check them they had changed the Server names to an old version. So, if I put in mboxhosting.com I would save it and when I went back in it would have changed it to mail.{domain}
I have contacted my hosting service but they say it is an Outlook problem. Has anyone any idea how I solve this problem?
