Message Text

There's an error in your Outlook Web App configuration.%n%nThe authentication type on the /owa virtual directory is set to Anonymous. This check box must be cleared for Outlook Web App to function correctly.

Explanation

This Error event can occur if Internet Information Server (IIS) has been used to configure the authentication settings for the Microsoft Office virtual directory. Outlook Web App authentication settings should be configured only by using the Exchange Management Console or the Exchange Management Shell.

User Action

To resolve this error, do one or more of the following:

  • Correct the setting by using the Exchange Management Shell.

    1. On the computer that is running Exchange Server 2010 that has the Client Access Server role installed, open the Exchange Management Shell.

    2. Use the Set-OwaVirtualDirectory cmdlet to reset the authentication method. For example, if you have forms-based authentication turned on, use the following command to reset it:

      set-owavirtualdirectory -identity "<server name>\owa (default web site)" -formsauthentication $true

    3. You may see a warning that the cmdlet ran successfully but that no change was made. Disregard this warning.

  • Contact a Microsoft Support professional to resolve this issue. To contact a Microsoft Support professional, visit the Exchange Server Solutions Center. In the navigation pane, click Assisted Support Options and use one of the assisted support options to contact a Microsoft Support professional. Because your organization may have a specific procedure for directly contacting Microsoft Product Support Services, be sure to review your organization's guidelines first.
