I'm trying to log in using the Office 365 but I keep getting this error!

Hello Rajat,

There are few factors that can contribute to the issue that you have. The password might not meet the requirements needed or you are using the same password that you recently used in the said account. Kindly provide the information below for us to better isolate your concern:

• Where are you trying to login? Are you trying to access Office 365 through the web?
• What is the exact activity that you are trying to perform when you get the error message? Are you trying to create a Microsoft account or install an Office application?

We suggest that you check this link if you are trying to create a Microsoft account for the first time that you can use to sign in to your Office 365.

Do come back with the required information and we would be glad to assist you.

Did this get resolved? I have the same issue:

I resolved it by using complex password generator (http://passwordsgenerator.net) for new password. After changing password and logging in, I then went in to admin console and changed my password to something I could remember.

Note: Up until using the password generator I was attempting to create passwords that I have never used in o365. I don't know if the machine learning algorithm was just evaluating my password history or the entire internet. I feel like it was the entire internet.
