Wait for the Lockout Period to End: Sometimes, simply waiting for a certain period can resolve the issue. The lockout period can vary, but it's typically around 30 minutes to an hour.
 

Reset Your Password:

Contact Your Admin: 

If you are part of an organization, your account administrator can unlock your account for you. 

Provide them with any necessary details about the lockout and any error messages you received. 

Check for Account Security Issues: 

If you suspect your account was locked due to suspicious activity, make sure to run a full security check. 

Review your recent activity in your Microsoft account settings to ensure there is no unauthorized access.
