You open the Outlook 2003 calendar, and then schedule a meeting.

You open the scheduled meeting.

You use the Live Meeting toolbar to convert the meeting to a Live Meeting.

In this scenario, the meeting is not converted to a Live Meeting. Additionally, you receive the following error message:

An error occurred while executing this command. If this error persists, please contact your Live Meeting administrator.
