Additional sign-in or account-related issues within Microsoft Teams for business
This message usually means the account has been temporarily blocked by Microsoft’s security systems because of repeated sign-in attempts or unusual activity.
Recommended steps:
- Stop repeated sign-in attempts for now. Repeated retries can keep the block active.
- Start with the Microsoft Sign-in Helper. It checks the account and guides the next recovery step.
- If the account is an Outlook.com or Microsoft personal account, use the unblock flow from Sign-in Helper.
- If prompted for a security code, any phone that can receive text messages can be used; it does not need to already be associated with the account. The code expires after 10 minutes.
- If the password may have been changed or the account was accessed by someone else, use Forgot my password on the sign-in page, then choose I think someone else is using my Microsoft account.
- If normal reset steps do not work, complete the Account recovery form. For the best chance of success, complete it from a device and location previously used with that account.
- If the sign-in page does not show a Next option and instead indicates the account is locked, use the aka.ms/ link shown in that window to submit the account reinstatement request. After submitting, do not send duplicate requests because that can slow review.
Important limits:
- If two-step verification is turned on and none of the alternate verification methods are accessible, support cannot reset or change the account details.
- If the issue is only in Outlook mobile, updating to the latest Outlook mobile app can help if recurring password prompts started after app security standards changed.
After access is restored, review recent sign-in activity on the Security basics page and change the password if any activity is not recognized.
