I have permissions being changed inside Exchange, at the Org and Site Levels, mainly some accounts being removed from any permissions and other accounts being added, or accounts that suddenly have service account admin rights. Of course, everyone denies making changes. Is there any way to track which accounts are making the changes? I already have changed some of the passwords on the accounts. This is for Exchange 5.5 SP4. Also, does Exchange 2000 allow the ability to track changes? Thanks, Rob Gangemi Rob@xxxxxxxxxxxxxxx
