A few days ago my hotmail email stopped working in Thunderbird- a box appears asking me to enter my password for ---email address--- on imap-mail.outlook.com. When I enter the password (yes, it is correct and I have logged into the webmail version) I get a second box telling me the login failed. Last night I began getting the same messages for one of my other emails, a business email address... Login to server imap.hosts.co.uk failed and additionally now my last email address is doing the same. I looked up the server settings and tried to check they were all ok but all appeared as it should be. I am at a loss. I went though the options in this helps section about emails but none of the options were applicable. Any help appreciated.
