SYMPTOMS
When you use a Collaboration Data Objects for Exchange (CDOEX)-based program to save an appointment item to another user's calendar in a Microsoft Exchange Server 2003 organization, you receive an error message on the Results page. The error message resembles the following:

Result

Description:Transaction failed to commit for an unknown reason.

Source:CDO.Appointment.1

Number:-2147168254

This problem occurs after you apply hotfix 895949.

Microsoft Office Outlook Web Access clients may receive a different error message. When you try to modify a shared calendar item in Outlook Web Access, you may receive the following message:

You do not have permissions to modify this item



CAUSE
This problem occurs because hotfix 895949 introduces a change in the implementation of the &quot;Send As&quot; user right. This change was introduced to give administrators more direct control when they assign the &quot;Send As&quot; user right.
