Mail Security automatically creates the following user groups and assigns them access when you install the product:
The user groups are domain-wide for Active Directory. You can use the Active Directory Users and Computers Microsoft Management Console (MMC) snap-in to change membership in the groups.
Users must be designated in one of the SMSMSE user groups to access the product. For example, administrators who are not in one of the SMSMSE user groups are not granted access to Mail Security. Adding a user to the SMSMSE Admins group does not automatically grant the user Windows Local Administrator, Windows Domain Administrator, or Exchange administrator rights.
Security is also set for the Mail Security registry key and file folders during the security set-up process. You must have administrator access to the local servers and domain administrator rights for the security set-up to proceed.
