What can I properties can I look at with MFCMAPI to determine if a folder is a Managed Folder, and what properties get added to individual items (specifically for retention)?

Hi You don’t post version of exchange. Outlook folders are identified as being managed by a Managed Folder policy by additional MAPI properties that are added to the folder(s). PR_MANAGED_FOLDER_COMMENT PR_MANAGED_FOLDER_ID PR_MANAGED_FOLDER_INFORMATION If a mailbox is removed from a Managed Folder policy, these MAPI properties are not removed from the folders within the mailbox If managd folder isn't managed by policy, you can not find special properties If you still have problem, you can post thread to development http://social.technet.microsoft.com/Forums/en-US/exchangesvrdevelopment/threads
