It's been a week now and Thunderbird still isn't working 100%. I managed to install one of my email accounts ( Talktalk ) with no issues but it still not working properly. I can't ad my Hotmail email and all my log in details are correct. The problem is I never get the dialogue box which gives you options all I get is a small white box with a cross and that's it ! I just don't get a choice to do anything and I think this is why I can't install my Hotmail email account. The options box may be asking for an 0Auth2 code but I can't see it so I'm assuming there is an issue with the Thunderbird app ! I have a Chromebook and have installed Thunderbird about 25 times using Linux but always end up with the same problem ! Any help would be appreciated. Thank you.
