This issue just started happening, I can still log in as Administrator and I can open the EMC but almost all the areas are greyed out and have a gold lock icon on the widows. This is a server we have been using for years with no issues.
Here are the groups that the administrator account is part of.
Administrators, Domain Admins, Domain Users, Enterprise Admins, Group policy Creator Owners, Exchange- Organization Managment, Schema Admins, Exchange - Import Export Permissions Role Group.
I created a new user and gave the following rights - Domain admins, Exchange - Organization Managment. This account works completely normally in the EMC.
I also Deleted the Administrator user profile on the Exchange server and legged in and recreated it but it still has the issue.
