I have an Exchange 2003 environment. It has some "issues" and we are hastily migrating to new machines. However, I need to keep the current setup running just a little longer. The mail stores seem to be having an issue coming offline at various times and I see errors relating to the background cleanup. I'd like to completely disable that for the time being. I have set the schedule on the database tab of each database to custom and then whited out all available so it never occurs. Is there anything else I need to do to disable the background cleanup?
