SUMMARY
''When you log on to Microsoft Outlook Web Access (OWA), and your mailbox is stored on a Microsoft Windows Small Business Server 2003-based computer, you may not be able to view the contents of your Inbox or your Calendar. This issue occurs if the Trend Micro OfficeScan program has added a custom MIME type to the default Web site. To resolve this issue, remove OfficeScan, reinstall OfficeScan on a virtual Web site other than the default Web site, and then delete temporary Internet files from the client computer. You can also work around the problem temporarily by removing the custom MIME type.''



SYMPTOMS
If your mailbox is stored on a Microsoft Windows Small Business Server 2003-based computer that is running Microsoft Exchange Server 2003, and you log on to Microsoft Outlook Web Access (OWA), the contents of your Inbox or your Calendar are not displayed. Instead, you experience the following symptoms:  When you try to view items in your Inbox, an hourglass appears, and you receive the following message:

Loading...

 When you try to view items in your Calendar, an hourglass appears, and you receive the following message:

Updating view...



Additionally, a warning message that is similar to the following may be displayed in Microsoft Internet Explorer:

An error occurred has in the script on this page.

If you double-click the warning message on the status bar, or if Internet Explorer is configured to always display a message when a Web page contains an error, you receive an error message that is similar to the following:

Problems with this Web page might prevent it from being displayed properly or functioning properly.

If you click Show Details in this error message, you receive an error message that is similar to one of the following:

Line: 1005

Char: 112

Error: 'null' is null or not an object

Code: 0

URL: https:// /exchweb/6.5.6944.0/controls/ctrl_calendarview.htc

Line: 58

Char: 2

Error: Object doesn't support this property or method

Code: 0

URL: https://ServerFQDN/exchange/username/Calendar/?cmd=contents



CAUSE
This issue may occur if the following conditions are true:
 * The OfficeScan program that is included in Trend Micro Client/Server/Messaging Suite for Small and Medium Business (SMB) 2.0 is installed on the server.
 * The OfficeScan program is installed on the default Web site in Microsoft Internet Information Services (IIS).

This issue occurs because OfficeScan adds a custom MIME type to the default Web site and to all virtual directories that are contained in the Web site.



RESOLUTION
To resolve this issue, remove and then reinstall OfficeScan on a virtual Web site that is not the default Web site and then delete the contents of the Microsoft Internet Security and Accelerator (ISA) Server Web cache on the server. Next, delete the temporary Internet files on the client. To do this, follow these steps.

Note To help make sure that your computer is secure as you follow these steps, disconnect your computer from your network before you start. After you complete these steps, reconnect your computer to your network.  Remove OfficeScan from the server, and then reinstall OfficeScan on a virtual Web site other than the default Web site in IIS.

For additional information about how to do this, contact Trend Micro or see the documentation that is included with OfficeScan. For additional information, visit the following Trend Micro Web site:

WORKAROUND
To work around this issue, remove the custom MIME type that OfficeScan added to IIS and then delete the contents of the ISA Server Web cache on the server. Next, delete the temporary Internet files on the client computer. To do this, follow these steps.

Note This workaround restores OWA functionality. However, because other issues may occur when you install OfficeScan on the default Web site, we recommend that you use the procedure that is described in the &quot;Resolution&quot; section.
