XFOR: Netscape 4.x Cannot Delete Appointments in Calendar Using OWA

Users who use the Netscape Browser cannot delete more than one appointment for each Outlook Web Access (OWA) session. No error messages are returned, nor is any indication of a problem given. Yet, reloading the page reveals the deleted appointments still exist, and can still be opened and edited.

Active Server Page (.asp) files (which are responsible for OWA communication) in the Request and Response directory may be out of sync.

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

To delete the appointments, the user must exit the mailbox, quit the browser, log back on to the mailbox, and then delete the appointment.

Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5.
This problem was first corrected in Exchange Server 5.5 Service Pack 3.
