    Hello

    There's currently a global outage affecting some Microsoft services, including Outlook, New and Classic Outlook apps, OneDrive, Copilot and others. It is an issue on Microsoft's end. Service status can be monitored here https://status.cloud.microsoft/

    Or via Msft's X/Twitter page: https://x.com/MSFT365Status/status/2120938282204688468

    Restore access directly through Yahoo before changing Outlook, because verification messages sent to the inaccessible mailbox must be handled through Yahoo’s Sign-in Helper or configured recovery method rather than through Outlook.

    1. Recover or verify the Yahoo account

    1. Try signing in to Yahoo Mail in a web browser.
    2. If Yahoo accepts the login, check whether the verification message is visible there.
    3. If browser login also fails—or Yahoo sends the code only to the locked mailbox—use Yahoo’s Sign-in Helper. It uses the recovery phone number or alternate email previously associated with the account.^1^
    4. If no usable recovery method is offered, this is a Yahoo account-recovery problem. Outlook cannot retrieve the verification message until Yahoo restores access.

    Do not change the Yahoo password merely to repair Outlook unless Yahoo requires it for recovery. Password changes happen at the email provider, after which the stored password or authorization in Outlook must also be updated.^2^

    2. Reauthenticate Yahoo in Outlook on each device

    Once Yahoo webmail works, reconnect each Outlook client separately. Yahoo recommends reauthenticating the account in third-party mail applications.^3^

    Classic Outlook on Windows

    1. Open File → Account Settings → Account Settings.
    2. Select the Yahoo account and choose Repair or Change if available.
    3. Complete the Yahoo sign-in window and approve Outlook’s access.
    4. If reauthentication is not offered, remove only the Yahoo account through File → Account Settings → Account Settings → Remove.
    5. Add it again through File → Add Account, enter the Yahoo address, and complete Yahoo’s sign-in process.

    Removing the account from classic Outlook does not deactivate the Yahoo mailbox, although locally cached content is removed.^4^

    Outlook on the phone

    Remove the Yahoo account from the Outlook mobile app, add it again, and complete the Yahoo authorization page. Removing it from the app does not delete the Yahoo account itself.

    3. If classic Outlook never displays the Yahoo sign-in prompt

    For Outlook for Microsoft 365, Microsoft documented a Yahoo synchronization problem that could leave stale OAuth credentials and prevent Outlook from requesting a fresh sign-in. The service issue was fixed on March 20, 2026, but saved credentials can still require clearing.^5^

    Use this branch if classic Outlook is not syncing and does not ask you to sign in, particularly with errors 0x800CCC0E, 0x800CCC0F, or 0x80070057:

    1. Close Outlook.
    2. From Start, open Credential Manager.
    3. Select Windows Credentials.
    4. Under Generic Credentials, find entries beginning with MicrosoftOffice16_Data:OAUTH2.
    5. Expand them and identify entries containing tp_yahoo_imap_Oauth2.
    6. Remove all such Yahoo OAuth entries for the affected account.
    7. Reopen Outlook and complete the Yahoo sign-in.
    8. Restart Outlook once more if synchronization does not begin immediately.

    This removes saved authorization credentials, not the Yahoo mailbox or Outlook account.

    4. App-password branch

    If Outlook asks specifically for an app password, or the account was configured manually as IMAP rather than through Yahoo’s sign-in page:

    1. Open Yahoo Account Security.
    2. Under External connections, choose Create app password.
    3. Generate a password for Outlook.
    4. Paste that generated password into Outlook instead of the normal Yahoo password.^6^

    An app password is conditional; it should not replace the normal Yahoo web password or Yahoo account recovery.

    Exact mobile error

    If the phone displays the exact message “Access Denied: Login Error”, Microsoft identifies that as denial of access to the Outlook Mobile product. Microsoft support agents cannot unblock it; for a managed work or school account, the documented route is the organization’s IT administrator.^7^

    For a personal Yahoo account, first complete Yahoo recovery and reauthentication above. If that exact mobile error remains while Yahoo webmail and classic Outlook work, report the precise message through Outlook mobile support.
