XCCC: "Authorization Failed" Error Message When You Try to Access Mailbox or Public Folder in Netscape Navigator (322213)

SYMPTOMS

If you use Netscape Navigator to access your mailbox or public folders through Microsoft Outlook Web Access, you may intermittently receive the following error message:

Authorization failed. Retry?

This occurs after you are already successfully authenticated against the resource. It typically occurs when you try to perform a new operation such as creating a new e-mail message or switching to another folder.

WORKAROUND

To work around this problem, use one of the following methods.

Method 1

When you are prompted for credentials during logon to Outlook Web Access, supply them in the following manner:

Username: Windows_NT_Domain\username
Password: password

Method 2

In Exchange System Manager, expand the tree down to the server that is running Outlook Web Access.
Click the Protocols container, and then click HTTP.
Expand the virtual server for Outlook Web Access (the default is named "Exchange" Virtual Server).
Right-click the "Exchange" Virtual Directory, and then click Properties.
Click the Access tab, and then click Authentication.
In the Default Domain box, type the Windows domain name that houses the user accounts. If there is more than one Windows domain with user accounts, type \ in the Default Domain box to tell Microsoft Internet Information Services (IIS) to search all trusted domains.
