We have several service accounts that are not being actively maintained and last Friday, I did some research and set up a MRM policy for those service accounts to automatically permanently remove any email messages in the Inbox and Deleted Items, older than 90 days. Today, I did an audit and the policy did not work.I double checked the settings:Organization > Mailbox > Managed Folder Mailbox Policies > 90 Day Limitiation: Applied to Deleted Items and InboxOrganization > Mailbox > Managed Default Folders > Deleted Items > Permanently Delete (Managed Content Settings):Message Type: All Mailbox ContentLength of Retention (days): 90Retention period starts: When DeliveredAction to take: Permanently DeleteIt's the same thing for the Inbox > Permanently Delete (Managed Content Settings)I checked to make sure that the specific mailboxes has the MRM policy associated with it.I have the Schedule Assistant running every morning at 5 am; event logs confirmed that it started at 5 am and completed with no errors, all mailboxes processed.I attempted to do a manual schedule assistant for a particular mailbox, no errors but the mailbox is not adhering to the policy. (IE: There's email messages starting from May 8th, 2009.)Is it not working because the messages don't have a timestamp to identify that it needs to be removed?

Off the top of my head it looks ok. Did you setup a log file? It might help diagnose the problem.use the cmdlet to enable the logging. Parameter Possible value Description RetentionLogForManagedFolderEnabled True of False Messages that reached their retention limit will be logged in the log files. JournalingLogForManagedFolderEnabled True of False All journaled messages by Managed Folders will be logged.

SubjectLogForManagedFolderEnabled True of False All subjects of the messages processed by Managed Folders will be logged in the log files otherwise it will be blank. LogPathForManagedFolders String Where the Managed Folder assistant will use to create the log files. The default path is C:\Program Files\Microsoft\Exchange Server \Logging\Managed Folder Assistant LogDirectorySizeLimitForManagedFolders Data Maximum size limit to be kept in Exchange Server without removing the oldest log information.

Hi, I suggest you read following article to know how Retention Periods Are Calculated for Items in Managed Folders http://technet.microsoft.com/en-us/library/bb430780.aspx Note: You can use MFCMapi tool to check following three properties of the message: - PR_MESSAGE_DELIVERY_TIME - PR_CLIENT_SUBMIT_TIME - PR_LAST_MODIFICATION_TIME In addition, I would like to explain that you can run Start-ManagedFolderAssistant to force Messaging Records Management (MRM) processing of mailboxes on the servers: http://technet.microsoft.com/en-us/library/aa998864.aspx Mike Shen TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com
