Outlook Prompting for Password but will not Accept Password

Outlook Prompting for Password but will not Accept Password

    Cause

    Outlook limits its choices of authentication schemes to schemes that are supported by RPC. But the authentication schemes don't include Modern Authentication.

    Resolution

    Important

    Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.

    Create the following registry key to force Outlook to use a newer authentication method for web services, such as EWS and Autodiscover. We recommend that users force Outlook to use Modern Authentication.

    1. Exit Outlook.

    2. Start Registry Editor by using one of the following procedures, as appropriate for your version of Windows:

      • Windows 10, Windows 8.1, and Windows 8: Press Windows Key + R to open a Run dialog box. Type regedit.exe, and then press Enter.
      • Windows 7: Click Start, type regedit.exe in the search box, and then press Enter.

    3. In Registry Editor, locate and click the following registry subkey:

      Console
  1. HKEY_CURRENT_USER\Software\Microsoft\Exchange

  2. On the Edit menu, point to New, and then click DWORD Value.

  3. Type AlwaysUseMSOAuthForAutoDiscover, and then press Enter.

  4. Right-click AlwaysUseMSOAuthForAutoDiscover, and then click Modify.

  5. In the Value data box, type 1, and then click OK.

  6. Exit Registry Editor.

2. Reset the login settings for Outlook

  1. Go to Control Panel and click on Credentials Manager.

  4. Click on Details and choose Remove from vaults.
  5. Click Yes on the warning box.
  6. Repeat the steps until you remove all the credentials associated with your email address.

  2. Choose Account settings in the Account settings section.

If the first solution did not work out for you, you could also try to verify if the option Prompt for credentials is not checked in profile as this could be another cause for this message to keep popping out.
