When you try to log on to an Exchange Server 5.5 computer using Outlook Web Access (OWA), you may receive the following error message:

Error Type:
Microsoft VBScript runtime (0x800A01A8)
Object required: 'Application(...)'

To resolve this problem:

  1. Start the Internet Information Server (IIS) Microsoft Management Console (MMC) snap-in, and expand the Transaction Server folder.
  2. Click Computers, click My Computer, click Packages Installed, click IIS In-Process Applications, and then click Components.
  3. Delete the IISWAM.1_Root_Exchange component.
  4. Click the Internet Information Server folder, and then click Default Web Site.
  5. Right-click the Exchange virtual directory, and then click Properties.
  6. Under the Application Settings section on the Virtual Directory tab, there are three buttons: Remove, Configuration, and Unload. Click Remove, click Apply, and then click OK.
  7. In Control Panel, double-click Services, and stop the IIS Admin Service.

NOTE: This also stops the FTP Publishing Service and the Web Publishing Service.

  1. Return to the Exchange virtual directory properties. The Configuration and Unload buttons are unavailable.
  2. Click Create.
  3. Click Apply, and then click OK.
  4. In Control Panel, double-click Services, and start the IIS Admin, FTP Publishing, and Web Publishing Services.
