Outlook 2007 does not send out meeting cancellations if you remove all invited attendees from a previously created appointment

In Microsoft Office Outlook 2007, if you remove all invited attendees from the To field in a previously created meeting, you receive the following message: If you click Yes in the message, the meeting page closes and saves the meeting. However, Outlook does not send out meeting cancellations to the attendees.

Note, after you install the update in the Microsoft Knowledge Base article 961752 or Office 2007 Service Pack 2 you receive the following error instead:

This issue occurs because Outlook cannot send meeting cancellations to attendees when there are no recipients in the To field.

To work around this issue, use one of the following methods.

Method 1

Cancel the meeting without saving it in the organizer's Calendar folder. To do this, follow these steps:

1. Open the meeting in the organizer's Calendar folder.
2. On the Recurring Meeting tab, click Cancel Meeting in the Actions group. This sends meeting cancellations to the attendees and removes the meeting from organizer's Calendar folder.

Method 2

Remove attendees from the meeting, but save the meeting in organizer's Calendar folder. To do this, follow these steps:

1. Open the meeting in the organizer's Calendar folder.
2. On the Recurring Meeting tab, click Scheduling Assistant in the Show group. This opens a page that has a list of all the attendees and the organizer.
3. Under All Attendees, click to clear the check boxes next to all the attendees.
4. Click Send. Meeting cancellations will be sent to all attendees. Also, the organizer can save this meeting in the Calendar folder.
