Using classic Outlook for Windows in business environments
Dear TC123DH
Thanks for using Microsoft products and posting in the community.
For your situation. Your Microsoft account is being asked to change its password repeatedly.
According to your description, you are spamming on Groupme causing your account to be locked and need to be unlocked.
After you were asked to enter your verification information, you reset your password to unlock your account, but you were locked out again when you logged in.
You can use the method below:
If you are logging into Groupme on your cell phone, you can log into account.microsoft.com on your computer and log into your account. If you still need to change your password to verify it, you can reset your password and log in, and after you have successfully logged in, you can log into your account in the “Security” section. “When you have successfully logged in, you can check whether there is any information that you have not logged in personally, if so, it is very likely that your account information has been leaked.
If it is, it is very likely that your account information has been compromised. If the same thing happens on the computer side, you can change your password and log in to the account the next day if you make sure that the device does not have a proxy turned on and that you are in your country and have not traveled abroad. It's possible that the previous account information wasn't synchronized to the Microsoft account, causing the true situation to keep repeating itself.
You can also change your browser to log into your Microsoft account.
I hope the above information can help you.
Looking forward to your reply.
Best wishes
