I understand, and could you tell me how long it takes to detect suspicious activity?

Hi Seth! My name is Darhyl and I’d be more than happy to help you with your query.

I'm sorry you are experiencing this with your Microsoft Xbox account.

Just a gentle reminder that we are only Microsoft users like you here in the community. We are not Microsoft employees and we do not have tools to access any Microsoft System.

Based on your description and since you mentioned that your account is locked due to suspicious activity, I highly recommend you submit an account reinstatement form as a last resort to unlock your account:

https://www.microsoft.com/en-us/concern/AccountReinstatement

You may receive the results via email within 48 - 72 hours.

If the account has been unlocked but you are still unable to recover your account, I just want to confirm when did you last successfully sign in to your Microsoft account? If you have not logged into your account for more than two years and it has been closed due to inactivity, you will not be able to use the Account Recovery Form to recover your account. Reference: https://support.microsoft.com/office/7c0a9fa7-0982-b7c6-fd72-df852b63699f

Did you have two-factor authentication (2FA) active on the account? If you do have the 2FA active, are you able to access the second factor of authentication? If so, please try resetting your password. Detailed steps on resetting your password can be found in the following support article: https://support.microsoft.com/office/eff4f067-5042-c1a3-fe72-b04d60556c37

Important: The account recovery form can only be used if two-step verification isn't turned on. If the feature is enabled, the only way to recover the account is to regain access to your two-step verification phone number.

If you did not have 2FA active on the account, and the account was not deleted due to inactivity, you will need to try the Account Recovery Form: https://account.live.com/acsr

Detailed steps on how to use the Account Recovery Form can be found here: https://support.microsoft.com/office/b19c02d1-a782-dee6-93c3-dc8113b20c42

Microsoft takes account security very seriously, that's why Account Recovery is an automated process with no human influence. If you don't have the correct information, you may not be able to get through account verification using the Recovery Form.

The Account Recovery Form requires adequate information to prove that you are the owner of the account. The Account Recovery Process can be a time-consuming process, but providing as much info as possible from the start of the process will increase the possibility of being verified by the automated process. You'll need to keep trying until you're verified by Microsoft.

Remember to use a familiar device from which you've frequently accessed your Microsoft account, as well as a familiar location. Microsoft will review your responses and respond within 24 hours. If you are verified, instructions on how to log back into your account will be sent to you, and if you are not verified, you will need to submit the Account Recovery form again. You can do this up to 2 times every 24 hours.

It's important to note that Microsoft Support will not be able to grant you access to your account, you will be sent back to the Account Recovery pages that have been linked above.

If your Microsoft account recovery request was not granted or was unsuccessful, please click the attached link for more information: https://support.microsoft.com/office/dc56c3e3-dff0-4ed5-8edb-60290eea6b53

While it might not be the outcome you are looking for, if you’re unsuccessful in recovering your account, then you will need to create a new Microsoft account. You can do that by clicking this link: https://signup.live.com/

Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.

Best regards,
Darhyl

These messages may mean one of the following: There's a temporary problem with the Xbox Live service. Your Xbox Live account has been temporarily blocked because the system detected suspicious activity. The profile stored on your Xbox 360 console
is corrupt.

My research online suggests that code happens when the account is in a different region than you physically live in or there has been fraudulent activity detected on your account.

Please contact phone support for more assistance with that code. Only they will be able to help you.
