Hi, I have a strange problem with viewing the content of some public folders this is not applicable to all of them. Despite the fact that I have full rights on problematic folder , I can not open any documents, I get an error saying : "The custom form could not be opened. Outlook will use and Outlook form instead. You don't have appropriate permission to perform this operation." , if I click ok , I get "Can't open this item. You don't have sufficient permission ..." Those errors message are ~wrong~ as first I have full rights and secondly no custom form were installed in those folders. Other information , the folder content display is incorrect like if Outlook was not able to read the folder content: I see a list of item but the From , Subject , Size fields are empty , I can see only the document type and the Received fields. I can not unfortunatly restore a "correct" public folder version as we discovered the problem far after the backup retention policy time.... What I tried to do to fix this was : - force permission from top level folders - move folders around with new permissions - restore exchange to a test enviroenemnt - run defrag, eseutil .... - run outlook /cleanview - upgrade to exchange 2003 on test env No luck with all of this , if anyone can advise me or help, really appreciated ! Thanks, Maya
