When you manually modify permissions in Exchange 2000, you may find that the permissions are reset to their default values when you perform either of the following tasks:
Reinstall Exchange 2000.
Apply an Exchange 2000 Server service pack to Exchange 2000 on a clustered server.
This behavior occurs if you manually modify permissions at the Exchange 2000 organization level or to the top-level public folder hierarchy (TLH) in Exchange 2000. For example, this behavior may occur when you perform the following procedure:
Right-click a public folder in Exchange System Manager, click Properties, and then click the Security tab.
Click to clear the Allow inheritable permissions from parent to propagate to this object check box, and then click Apply.
Click the Everyone group.
In the Permissions list, click to clear the Allow check box next to Create top level public folder, and then click OK.
Note that this behavior occurs only if you reinstall Exchange 2000 or if you apply a service pack to Exchange 2000 on a clustered server. You do not experience the behavior that is discussed in the "Symptoms" section of this article when you apply any post-Exchange 2000 Server Service Pack 3 (SP3) hotfixes to Exchange 2000 on a clustered server.
To work around this behavior, keep track of the permissions that you modify manually, and then reapply the permissions after you reinstall Exchange 2000 or after you apply a service pack to Exchange 2000 on a clustered server.
This behavior is by design.
The following scenario is another example of when you may experience the behavior that is discussed in the "Symptoms" section of this article.
Start Exchange System Manager on a clustered server.
Right-click OrganizationName, and then click Properties.
Click the Security tab.
Click the Everyone group, and then click Remove.
Apply an Exchange 2000 Server service pack.
