Past entries mysteriously disappear on my outlook.com calendar (converted from Hotmail account). I pay an extra monthly fee to .msn so this is especially irritating. The time is arbitrary; sometimes I can see one week back, sometimes two. The settings and options available on the online/Hotmail outlook calendar are extremely limited and don't seem to address this.

I am syncing to I-phone 4 and have sync all events checked. The entries thankfully still appear on my I-phone, but not my computer/online calendar.

Help! and Thanks.
