During the TBird installation I am asked to enter user/email/password but after repeated attempts only get error saying info incorrect.

Question

After going through the Thunderbird setup on a Windows 8.1 computer, and after selecting IMAP instead of POP, I get to the point where it asks me to input name, email and password. However, when I do so, it invariably comes back and says my name and/or password are incorrect. Eventually, as I can go no farther in the setup process, I have to cancel out of setup. When I check for installed Thunderbird, Windows does not list it along with other programs in the add/delete window, I find no mention of Thunderbird, so I can't uninstall it. As I am attempting to use TBird with my gmail account, of course, the first time I tried this I got a snarky email from Google telling me that I was attempting to use an email client with lesser security, and giving me a link to go to if I wanted to continue with this less-secure strategy. I successfully set gmail to allow the installation of an email client, and again tried to install TBird, with the same result. I got another Google email acknowledging that I had reset my Google account to accept so-called less secure programs. Again, though, I got stymied at the same point and was again advised that the user name/email/password was in error.

Answer 1

I attempted to set up a Gmail account for my sister using Thunderbird to access her gmail account. I got the same result as the above message and could not get any further in the process than to be repeatedly told that the password or user name was incorrect, (which I knew they were not since that account has just recently been created). If I go directly to gmail, it will log on and allow her to view her messages easily, but attempting to use TBird it gives the same result every time. I take it that there is something going on with the authentication process in gmail, but it isn't clear to me what it means or how to deal with it in Tbird, so some clarification and elucidation would be really appreciated, she wants to use TBird since that is what she is used to and understands, and I would like to be able to insure that she can. My wife has a gmail account that is accessed through TBird and there is no problem with it and logging on to view the account, but my sisters new account is unaccessible with TBird.
