Microsoft Outlook 2007 – How to Hide Specific Recurring Appointments in the To-Do Bar

Sorry, it cant be done. Your best option would be choose the one month setting.

You could always go to the MS Office development blog and add it as a feature request.

Here's how you do this in Outlook 2010:

1. Decline the meeting so the person knows you aren't attending
2. Go to the deleted items folder and open the invite
3. Click "Tentative" and then "Do not send a response"
4. Open the appointment and then change your time to "Free"

These are the same steps that Microsoft says in Show a declined meeting on my calendar.

These steps only work when you just received the meeting invite. It will be difficult to find the meeting invite for declining one occurrence of a weekly meeting that has been running for a while.
