My office uses Exchange 2003 with Outlook 2007. I have about 40 users. On some users stations their deleted items remain forever or until deleted manually. On others they delete after a day or week. I cannot find what setting or policy that controls this. On all accounts on the Exchange General tab they are set to use Mailbox defaults. I don't have any custom polices in the Exchange manager.
It seems like some sort of user setting in Outlook but I cannot find it. All I have found is the checkbox to automatically delete items on exit and that is not checked on any of them. How ca I standardize this or at least adjust it on a per user basis?
