I experienced the same problem (although possibly for a different reason) when trying to use a gmail account with Windows Live Mail on a Windows 8.1 Laptop. I could log on to my G mail account using internet explorer. However the same password was rejected using the default settings in Windows live mail. I also received an e mail from G mail warning about a possible unauthorized log in attempt that was automatically blocked. I was directed to the link below to solve the problem.
Allowing less secure apps to access your account:

I followed the directions to allow less secure apps and now G Mail works fine with Windows Live Mail.
Kind Regards

Hi, I still get the occasional error but its generally OK. I just wanted to write and laugh at how Gmail thinks WLM is a less secure app? Haha. Well, I suppose, everything is less secure these days. Especially Gmail, as opposed to WLM.
At least WLM emails are stored on My PC, and not up in the clouds.
Just wanted to say this suggestion helped me too after I had to change Gmail login. Was tearing out what little hair had left
