We are in the process of migrating from a Windows NT domain, running Exchange 5.5 to a Windows 2000 domain with Exchange 2000. We are running in mixed mode, and have migrated many e-mail accounts with almost no problems - the exception being that users that have been migrated to the 2K domain, cannot access the Organizational Forms Library - and when they attempt to, it defaults to the Standard Forms Library.. Users still on the old NT domain, can access them just fine. Any ideas on where I can start to troubleshoot this? Thanks in advance, Dave
