Using Outlook 2010, some of my recurring (planned, not drafts) events is saving a draft to my Drafts folder every single minute as long as it's active.

An example taken from real life is that I have a calendar entry (Appointment) occuring every day from 24-09-2012 until 28-09-2012 from 08:00 to 16:00 (GMT+1) with a blue category, only one participant (me) with subject but without a place.

So every minute from 24-09-2012 until 28-09-2012 from 08:00 to 16:00, but not from 16:00 to 08:00, a new draft is automatically saved in my Drafts folder.

How do I get rid of that behaviour?

Addition here: Removing the offending event just allows a new one to take its place. There doesn't seem to be much on the sites - Microsoft calls it a "personal" issue, but there are more and more instances.
