Hi, I am managing an Exchange 2003 server that is well on the way to having its limit of 32766 ID's in the named property cache broken. Last year I traced it to inbound spam, and again this year it is adding named properties at an alarming rate. Here is a link that describes the problem better: http://anewmessagehasarrived.blogspot.com/2008/10/named-properties-bloat.html At the end of the article a commenter mentions that this bug was fixed with Exchange 2007 Sp1 RU8. Can anyone confirm this? I would like to use this as "one more reason" to move to Exchange 2010. Thanks.

How about an official Microsoft link to confirm the change? :) http://msexchangeteam.com/archive/2009/06/11/451596.aspxNeil Hobson | www.msexchange.org/neil_hobson | neilhobson.blogspot.com | twitter @NeilHobson

Thanks Neil, I really should search first. My bad. Found this too: http://msexchangeteam.com/archive/2010/07/29/455687.aspx -Paul

No probs - I should have mentioned that I have upgraded customers over the years from older E2K7 versions to RUs containing the fix and it does seem to have done the trick. Definitely another good reason to upgrade - good luck!Neil Hobson | www.msexchange.org/neil_hobson | neilhobson.blogspot.com | twitter @NeilHobson
