Corrupt Current View every Few Days

I have read about corrupted current views occurring every few months.
However, does anybody have any solution for corrupted view occuring every few
days?

Every few days I run I run Outlook.exe /cleanviews as per:
http://office.microsoft.com/en-us/ou...031101033.aspx

I then customize my view with Group By "From" with Shaded Group Headers,
Font, Color, etc. I typically have all Headers collapsed. In 2-3 days (Only
in my Inbox), the Headers will be expanded (un-collapsed) every time.

I have also checked my PST/OST several times.

Any MVP help will be most appreciated.
