Modified shared calendar view problem under Outlook 2007

[mymandala]

I modified a shared calendar view (either color formating or filter or
anything) under Outlook 2003/Exchange 2003 SP2. But users with Vista
+Outlook2007 get an "Impossible to open view" error message. Other
Outlook 2003 users don't have that problem.

I've tried deleting and re-open shared Calendar under Outlook 2007, no
success.

Only solution, was to re-create entirely the view under a new name,
give rights, and view shows up ok.

Any idea or solution?

Thx
Chris
