Dear Efe DURSUN,
Thanks for using Microsoft products and posting in the community.
I understand that you've been receiving a lot of unsolicited Microsoft CAPTCHAs and that this has caused you distress, and I understand how you feel.
You cancheck to see if there are any unusual logins to your account:
After logging in to your account, Manage Account > Security > Login Activity to see if your most recent activity was an abnormal login, or if you have logged in from another location.
Login URL: https://account.microsoft.com/
If you see the "Unusual Activity" section, be sure to:
- Tell us if this activity is related to you When you expand an activity. you can select "This is me" or "This is not me". These options are only located in the Unusual Activity section, so if you see these options, we need your feedback. With your help, we can troubleshoot false threats and block unauthorized access faster.
- Protect your account. If you're concerned that someone may have access to your account, we highly recommend going to the Security Settings page, where you can change your password and update your security settings.
You can also remove all trusted devices: Sign in to your Microsoft account, Security > Advanced Security Options > Logout from All Locations.

Someone is trying to log into your account andwe suspect that your account name may have been compromised, it's reassuring to know that you still have access to your account for now.
To prevent this from happening, you can remove login permissions for the current account name:
This method can be very effective in stopping intruders who already know the name of your account. To do this, click on this link ( https://account.microsoft.com/ ) and log in to your Microsoft account, then click on [Your Information] on the left, and then click on [Edit Account Information] on the right side of the screen that opens. In this interface, you can add an alias as a new login for your account. Due to the current security risks associated with your account, I recommend that you create an alias with an outlook.com extension that does not require authentication. (If you're using the custom alias below, you'll be prompted to verify that the alias exists.) You can only add an actual mailbox as an alias.
Then, you need to click [Set as Primary Alias] to the right of the new alias to make it the primary alias. After that, click [Change Login Permissions] at the bottom to remove the tick in front of the current account name. You have successfully removed the login privileges for your account name. You can test this by entering your account name in the sign-in screen, and Microsoft will alert you that the username does not exist, which will prevent you from signing in, the same person who tried to hack your account. Please note that in this case, you will not be able to log in with this account name. Remember the account name you changed. In addition, we tested that you can still send and receive emails using this account name, and that senders can use your account name as a recipient of emails, and email functionality is not affected.
Please note: Deleting the login permission for the current account name does not mean deleting the current account name. Do not delete the current account alias!
In addition,you can increase the security of your account by using the Microsoft Authenticator app, which helps you log in to your account using dual authentication. For more information, please refer to the following link: Microsoft Authenticator kullanarak oturum açma - Microsoft Desteği
I hope this information has been helpful to you. If you have any questions, please let me know and I will be happy to assist you further.
Thank you for your patience and support.
Have a great day.
