One of our clients asked us to configure Exchange 2010 to retain outgoing mail for a certain amount of time (independant of Outlook settings.) The idea is that an administrator has about 10 minutes to take a message out of a queue before it is sent out the organization.
I know this can be configured in Outlook, but this is not a valiable solution for us. I'm also aware that this causes queues to fill up, this is part of the consideration.
Is there a way in Exchange 2010 to configure this?
