Thunderbird has suddenly started recently to ask me for a password. And to my knowledge I am not able to provide this password as if I ever set up one some 15 years ago. I can never ever remember being asked for it before. Before it was taken over by Virginmedia.com, it was Ntlworld.com. And my email was and still is: [email removed]@ntlworld.com. I now get this enter your password for [email removed]@ntlworld.com on imap.virginmedia.com. When I enter all the passwords that I have used over the last few years, I get a message that either my user name ie [email removed]@ntlworld username is wrong. Or the password is wrong. As a result whilst I can see on my computer emails that go back to say 2010. They stop around May 2025. And of course I have had newer emails sent to me since May this year.. I also had about the 19th of this July to create a new method of signing in to Virginmedia.com as they had us create it as they had amalgamated to O2 the Telephone people. So now we sign in with a common password for VMO2. With regard to this new password, I tried it to sign in to my email. That did not work either. I can only surmise that being an old duffer I must have been and pressed the wrong button somewhere, months ago. I now realize that I generally normally never signed out from Virginmedia.com so I had not been aware that my emails were not being updated to my computer until being forced to generate this new VMO2 password. At 81 years old, this is all way above my capacity. Perhaps you might be able to help in this matter. Regards Cliff Edwards. P.S. What is an Imap?
