Hi, I'm a new newbie. In advance I'm asking for forbearance as I am really not too sure of how to describe the situation I'm having trouble solving. I have a 2+ year old iMac with 10.13.6. All was fine (I do also have parallels and Windows 10 on it) on the iOS side until I decided to change my email password. It was apparently a bad decision. I have an xfinity mail account. I can log on to it without a problem on their server. I can log in without a problem on my mail program on my Windows side, but I cannot change my password in Mac Mail. It just won't accept it, telling me it is unable to verify my password. I tried deleting it and re-adding it, but to no avail. What am I forgetting? Suggestions? Thank you!
