XCCC: You Are Unable to Delete E-mail Messages When You Use Outlook Web Access (313815)



The information in this article applies to:

  • Microsoft Exchange Server 5.5

This article was previously published under Q313815

SYMPTOMS

When you use Microsoft Outlook Web Access (OWA) to access your mailbox, you may notice the following errors:
  • You may receive the following error message when you try to delete e-mail messages:
    "Unable to delete item."
  • You may receive either of the following error messages when you click the Calendar folder:
    "Unable to set default formats and patterns."

    -or-

    "Unable to Render This view 424Object Required."
  • You proceed to the Inbox when you click the Contacts folder.

CAUSE

This behavior can occur because the public folder server is not accessible.

RESOLUTION

To resolve this behavior, users must have access to public folders. To do so:

  1. Make sure that you can use the ping command to search for the public folder server from the OWA server by the public folder server's Internet protocol (IP), network basic input and output system (NetBIOS) and fully qualified domain name (FQDN). You can add entries in the Lmhosts and Hosts files if it is necessary.
  2. If NTLM is the authentication method on the OWA server, the public folder server specified on the General tab of the properties of the private information store must be the Exchange Server computer itself.

    NOTE:To implement NTLM authentication for OWA, it is essential to have Internet Information Service and Exchange Server 5.5 on the same computer.

MORE INFORMATION

The public folder server is determined by the Public Folder box on the General property page for the Private Information Store container in the Exchange Server 5.5 Admininstrator program. This is the server on which all of the top-level public folders that are created by users who have home mailboxes on this server are stored. The public folder server is also the server on which the users on this private information store view the public folder hierarchy.
