Using Classic Outlook on Windows for personal email, calendar, and contact management
If the account is blocked because of multiple incorrect password attempts, use this recovery path:
- Reset the password to unblock the account. For Outlook.com accounts, a password reset is required to unblock access.
- If the error is specifically "You have tried too many times with an incorrect password", use the Microsoft account sign-in helper to check for account issues.
- If verification codes are not arriving or the block continues:
- try another verification method connected to the account
- try another network
- wait 24 hours before trying again
- avoid repeated attempts, because repeated requests can extend the block
- If the account is still locked after password reset, sign in at
https://account.microsoft.comand complete the unlock flow if prompted. - If the account cannot be unblocked with the security code or password change, use the sign-in recovery guidance in When you can't sign in to your Microsoft account.
If Outlook 2016 on Windows is involved, stored incorrect credentials can keep retrying and trigger lockouts. Installing the April 2, 2019 update for Outlook 2016 (KB4464502) addresses a known issue where Outlook 2016 could continue sending incorrect credentials after a canceled password prompt.
Also check whether the mailbox or OneDrive storage is full, because a full mailbox or storage can prevent sending or receiving mail.
