How to Navigate the SmartPost Error: Login failed for user ‘SmartPost’

Are you getting the error “Login failed for user ‘SmartPost’” after installing SmartPost in Microsoft Dynamics GP—even though the password is correct? You’re not alone. In this video, we explain why this error happens and exactly how to fix it.
