My problem is here
1. I created a account with my organization email when I activated MSDN subscription.
2. I activated the loud benefits built into your Visual Studio subscription.
Everything was fine by that moment.
A few days later, when I received the invite of company azure subscription from my company and I try to login azure portal of the company with my company account,
I can't login with the error "Incorrect user ID or password. Type the correct user ID and password, and try again."
Then, I changed password and tried a dozen times. It still didn't work. I am sure my user name and password is correct.
I appreciate that anyone can help me solve the problem.
