AADSTS900561: This endpoint only accepts POST requests. Received a GET request.

Hello, Microsoft

I was just quietly watching youtube when I suddenly received a notification about my office 356 account. So I immediately checked whether there was something wrong with my office account. And that was clearly the case when I could no longer log in to my account. I have tried all your tips, for example I tried to check if I could not log in to all my browsers and it was. And I also tried to use this link: portal.office.com on INTERNET OPTIONS at PRIVACY and that didn't help either. The email works but my password has been changed or hacked. Because I enter the correct password but it says that it is still incorrect. So I can't login to anything with this important office email.

I want to regain access to my Office 356 account.

It happened to the browser: CHROME but does not work on all browsers.

For further information:

Timestamp: 2020-08-04T15: 44: 06Z

Message: AADSTS900561: The endpoint only accepts POST requests. Received a GET request.

Is there any other way to fix this. Thank you in advance!

It was my school they changed their School-Name and also the School-Email to their new name. So that was that.

I have been seeing this for months there was usually a problem with duplicate passwords forced to change passwords. I knew were correct and foolish but had go along with it. There are no communications with the other end of this screen a failure to communicate.

I would change the password. Then go into the browser find old passwords that in most cases were correct. I tried to think it was just an automated process. Or there is someone trying to drive me crazy. I would try to keep a sense of humor about problems with IT! I call it IT' is some entity lives in the machine. I guess it is governed by logic protocells and my guess an algorithm. I hate IT. IT is a pain in @$%^ I don't have permissions.

I get mad as hell. Yes contact your IT dept sort of like hidden files Yes, I have had IT it

In addition the the steps that you already tried, you may need to add https://login.microsoftonline.com to your list of trusted sites.

In Chrome, go to:

Settings – Advanced – Content Settings Cookies – Allow – ADD – “login.microsoftonline.com” Unsandboxed plugin access – Allow – ADD – “login.microsoftonline.com”

You may also need to add "https://autologon.microsoftazuread-sso.com/"

If you're still having this issue feel free to send me an email at AzCommunity@microsoft.com and I can open a support case for you and help troubleshoot.

Thank you SO much! This fixed it for me as well, if anyone is still having this issue (although the instructions are a bit different now in 2023):

On your computer, open Chrome

At the top right, click "More" and then "Settings."

Click "Privacy and security" and then "Site Settings."

Click "Additional content settings" and then "Insecure content."

Next to "Not allowed to show insecure content," click "Add."

From here you just need to add these two sites:

login.microsoftonline.com

https://autologon.microsoftazuread-sso.com

After that it should work to send a code to your phone or whatever is needed to finish logging in!

Hi,

Just to let you know that I had this issue where an office pc could not log into email or any office 365 apps, e.g. teams, One Drive after a number of different tries all of the above I found that uninstalling office giving the pc a reboot then signing in with a admin account and installing office then logging on as the user fixed the issue hope this helps. You may get a prompt to reactivate office.

Ps. it seems to be happening when the user changes the password for some reason.
