I work for a school district that has not audited mailbox accounts in years. I would like to do a search/audit on our mailserver for accounts that have not been accessed in X number of days, and then have the flexibility to disable/delete accounts based on this information. What are my options for this? Thank you very much in advance!

Hi Jon, "Get-MailboxStatistics" should have the information that you are looking for (ie: Last Logon Time). You could run a query similar to the following to see all mailboxes that have not been logged onto since Jan 31, 2012: Get-MailboxStatistics | where {$_.LastLogonTime -lt "01/31/2012 12:00:00 AM"} | ft displayname, last* -Matt

LastLogon cannot really be relied up, because shared mailboxes will provide false information. The best option is to go after the actual AD accounts, you will need to query all domain controllers. Use oldcmp to look for old accounts. http://www.joeware.net/freetools/tools/oldcmp/ Simon. Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
