do anyone else see this event when archiving public folders?

http://seer.entsupport.symantec.com/docs/287672.htm

the article above tells me to remove exchange properties from any account mentioned in the event, assuming they will always be dead accounts etc, in our case they are not all dead accounts so this is not an option..

I can't see any way to synch an indevidual Public Folder as the functionality appears not to have been included, which makes testing solutions to this somewhat of a challenge, since all we can do is a full archive run against our Public Folder tree, this can take several days to complete

Anyone got any good ideas/tips around Public Folder archiving?
