Hi all,I'd like to track changes on our exchange server when an administrator modify the access permission on a mailbox. For example, if I set "Full mailbox access" on a user's mailbox I'd like to see this changes in the server eventvwr.Can I do this with Exchange "Diagnostic Logging" ?

hi, Mailbox permissions are stored in Active Directory, so the audit needs to be performed on a domain controller, not an Exchange server. you can set Audit Options on GPO to audit security activities on your server.and here there is detailed information ;http://www.msexchange.org/tutorials/Importance-Auditing-Exchange-2003-Servers.htmlregards,Mumin CICEK | Exchange - MVP | www.cozumpark.com | www.mumincicek.com

Thanks for your answer but in this way I cannot trace that kind of changes. Microsoft support told me that it's not opossible to track changes on mailbox permission and suggest me to take this toolhttp://www.quest.com/intrust-plug-in-for-exchange/Other ideas? :)
