HI ! I already tried this work around but it won't work, I don't know why. And even if it would work I still would have a problem because there also is a central forms system folder with this problem witch of course isn't visible on the installable file system. :-(( -----Original Message----- From: Alex Decarli [mailto:decarli@xxxxxxxxxxxxx] Sent: vrijdag 27 september 2002 13:38 To: [ExchangeList] Subject: [exchangelist] RES: Unchangeable MAPI permissions http://www.MSExchange.org/ try to this article: q270905 -----Mensagem original----- De: Robert Pouleijn [mailto:rpouleijn@xxxxxxxxxx] Enviada em: sexta-feira, 27 de setembro de 2002 03:46 Para: [ExchangeList] Assunto: [exchangelist] Unchangeable MAPI permissions http://www.MSExchange.org/ Hi all, I recently deleted a Security Group from our W2k DC. This Group was added to some public folders on our Exchange 2000 server. When I open a permissions dialog from a Public folder on a Mapi client the dialog shows a SID number for the delete group. In the past I was always able to delete these SID numbers from the permissions of a public folder. But now for some reason it fails. It even fails on the Exchange System Administrator saying: "invalid window handler". To make things worse; I delete the SID entry from the public folders with help of the installable file system on the M drive. After I had done this I read somewhere that you never should change the permissions on a public folder with the help of the installable file system. Does anyone know how you can somehow reset the permission on a public folder, so that a Mapi client can edit the permissions again? Many thanx !!! ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: decarli@xxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: rpouleijn@xxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
