Q: email password not getting recognized in email accounts

I am having major issues with my email.  I was using Outlook:2011 v14.4.3 for the mac, but was having so many problems with it that I abandoned it.  Outlook:2011 was not recognizing my password and I was continuously getting Authentication Failed messages, and needing to in put my password.  It would take my password sometimes, and sometimes not.  Now It won’t recognize it ever.

So I went to Apple's Mail for a while and then to Thunderbird because I like the features that it has.

Now Apple’s Mail and Thunderbird are both give me error messages and won’t recognize my information.

I know the information is correct, because I can go into my browser and go to Outlook.com (not to be confused with Outlook:2011.  I have an @outlook.com email address.)  and send and receive mail there.

I have recently upgraded to Mavericks 10.9.4

I have no idea what is happening, but I am pulling my hair out. Can anyone help??
