Number of named properties reached the quota limit (10026) – Event ID 9667

I came across this question on one of the forums and found that it was not documented in many places. As a result I though posting it here may help someone else in the future.

Event ID: 9667Failed to create a new named property for database "Storage Group1\General (TDEX01)" because the number of named properties reached the quota limit (10026). User attempting to create the named property: "besadmin" Named property GUID: 00020386-0000-0000-c000-000000000046 Named property name/id: "X-EN"

I have not had to complete this operation myself and I would therefore consider calling MS PSS as I think they have a registry fix for this however it does not seem to be publically available. I have read in other posts that this registry fix for Exchange 2007 works fine in earlier versions of Exchange however I would seriously consider confirming this directly with MS before try it or at a minimum make sure everything is backed up and verified before making the change on Exchange 2003.
