+ 0 Votes Enter Network Password box keeps popping up pamkay 7 years ago Hi, did you ever get this sorted? I am getting it too and it drives me potty. + 0 Votes Any resolution yet andi.lutter 6 years ago I am having this exact problem. I am using Outlook on a LAN that is connecting to the internet using NAT. The POP server is on a different network than my ISP. Initially, I could receive email but not send as my actual domain does not allow outgoing mail from outside the corporate network. When I changed my smtp server to that of my ISP, all of a sudden, Outlook started asking me for my user name and password for the POP server (even though the credentials in setup had been working before). It never successfully recognized those credentials, just kept asking and asking until I would eventually click <Cancel>. Now it tells me it cannot even find the POP3 server. My outgoing mail problem has been resolved but a new incoming mail problem has been created. Can anyone help? + 0 Votes please answer the following questions... Triathlete1981 7 years ago and i'll try to help. is this a work account? if so, are you using an in-house mail server or third party (out-of-house) mail server? if not, are you using outlook to access a third party email account like aol, yahoo, msn, etc? does this problem happen a lot? did you change your email settings?
