在 Windows 上使用新 Outlook 進行個人電子郵件、行事曆與聯絡人管理
Hello, thank you for reaching out to Microsoft Q&A.
You may receive this error if someone tried to access your Microsoft account and typed in an incorrect password multiple times. For security reasons, your account will be temporarily blocked.
So, check your Microsoft account recent activity page to see if there are any unusual activity in your Microsoft account -
https://account.live.com/Activity
If there is no unusual activity, sign in to the security settings page of your Microsoft account and enable two-factor authentication.
https://account.live.com/proofs/Manage
Under Additional Security, select Two-step verification to ON.
Then, make sure you have at least three verification methods to sign in.
Next, scroll down until you find the Sign out everywhere option - Microsoft will sign you out of your account from all the trusted devices, possibly within 24 hours.
If you are still experiencing the same problem after enabling two-factor authentication and resetting your password,
Go to the “Manage how you sign in to your Microsoft account” page here:
https://account.live.com/names/manage
Do you have other account usernames besides your default email address? If yes, you can use that email address to sign in. If you don't have another address, click Add email, create a new Outlook.com email account, and set it as your primary alias.
Use that email address to log in to your account.
Note: The email alias you add will share the same inbox, contact list, and account settings as your main email address. You can choose which email address to send mail from and log into your Outlook.com account with any alias; they all use the same password.
Check if you receive the same error when logging in with your new username (alias) and password.
