I have tried to add a hotmail account to Thunderbird because my Internet provider will stop e-mail support in the near future. I was able to add a hotmail account to Thunderbird, but I get the following error message when I try to receive e-mail in this hotmail account: "Configuration could not be verified – is the user name or password wrong?" (The hotmail website receives the e-mail.) User name and password is certainly correct. I have a 8.1 OS. Thank you.
