We are in mix mode with exhange 5.5 sp4 and exchange 2003 sp2 servers. We had on the 5.5 side a site with the ims service. On the ems side we saw it as a grayed out site. I followed ms article on removing a site for 5.5 and I saw it replicated on the 5.5 side but when I open esm for the 2003 side it is still their. I open the 5.5 admin on the exchange 2003 server and it is gone. I try to use the esm to try to delete the site/administrative group and the recipient policie of that site/administrative group but it doesn't delete it. Does anyone know how to remove the site/administrative group and the recipient policy of this site/administrative group.
