Hello, I am having some truble with office 2007. When I use outlook 2007's calendar and try to open a meeting that was created by an office 2003 I get this error message: "Cannot open this item. You changed one of the recurrences ot this item, and this instance is no longer exists" When I try to open the same meeting by the same user under a different version of office it is all OK. I hope someone got an answer 4 me... Aviv
