Does anyone have the rpcnofrontend.zip file or the executable so that I can setup Outlook Anywhere on Exchange 2003 without having to dive into the registry myself? Apparently this tool has worked wonders but it appears as though it has since been taken down. I need to activate Outlook Anywhere successfully so that the migration of mailboxes from Exchange 2003 to Outlook 365 can move successfully. (apparently, Outlook Anywhere has to be fully functional for this to happen).

In the server properties (snapin Exchange Managment), there are options:
backend rpc over http server
frontend rpc over http server
