@RonGouveiaCPACITP - assuming the Exchange export otherwise works okay, if I recall correctly, Exchange executes the path at the server not the client meaning the UNC to the workstation's local drive should be valid from the server. So if App Server is using LocalSystem account to run or any account where a challenge could appear, the export will fail. You can test by directly logging on to the server using the App Server account. Then in Windows Explorer just try to browse to that UNC path to the wkstn's share. If Windows challenges you with a prompt to provide login - password credentials then that's your problem. Or let's say you're not challenged but can't create files in that share that would cause it too. Before you do any of this, make sure your Exchange export itself work okays when pointing it to a regular path. Hope that helps.
