I had a very nice mail program called Mailbird but ATT has just informed us that we need 0Auth from now on. Yesterday after 6 hours searching for a security code, I decided to check the list and found that windows10 mail satisfies that. So I installed it, the problem being it is not working well at all. I have used in settings the reset button and it says its reset but I cannot change font size remove the background or any features. They are not talking to the program. what can I do? I currently cannot use the program for anything but receive mail yet on my laptop it works great. This is an HP desktop. I am currently up to date on windows update.
