I've encountered error when setting up MS Outlook (2003 and 2007). I've configured a POP3 email in MS Outlook. I've tested the settings such as user credentials, username and password, pop3, smtp configuration and even the ports.
I was able to receive/send email without issues for couple days. Somehow during the process of receiving emails, I got a pop up screen that asks for my user credential. I retyped the username and password along with the check box. It went away. After away when the outlook receive/send emails again, the pop up screen that asks for user credential pops up again.
I am wondering if there is a solution to resolve it permanently? Thanks
