Hi


im running outlook 2013 on Win 10 and it has stopped sending mail, it still receives and if i go into the settings and "test settings" a test email is sent and received. but idf i open a new mail draft and send i get the following error

Task 'a.....@.....net.com - Sending' reported error (0x800CCC13) : 'Cannot connect to the network. Verify your network connection or modem.'
