I am currently using a 13.3 MacBook with 4GB of memory and I recently downloaded OS X EL Capitan version 10.11.1. I mange my email accounts through Microsoft Outlook 15.15 and I am having trouble just sending emails not receiving them. It keeps telling me "Connection to the server failed or was dropped"
Is there something I need to change in the settings of the outgoing server or port number?
MacBook, OS X El Capitan (10.11.1)
