Running SBS2008 we are encountering situations where one user is no longer on any distribution lists, where another distribution list has the worng Keri on it, etc.... I am pretty sure these are human error, but have no way to know who might be doing it (we have a number of admins). Seperate from that, is there a way to log or monitor who is adding/removing users from lists?

This is more of an AD Sec than Exch audit. E.g http://www.windowsecurity.com/articles/auditing-users-groups-windows-security-log.html Configure auditing and maybe post in the AD forum for detailed steps.Sukh

Thank you!
