America Online (AOL) uses a proprietary e-mail system. In April 2004, AOL introduced a way that its subscribers can access their AOL e-mail messages from other e-mail applications, including Outlook, anywhere Internet access is available. You do not have to be directly connected to the AOL service to access your e-mail messages in Outlook. For example, if you are at work or traveling with a laptop computer, you do not need to first log in to AOL. AOL provides access to their e-mail server and your incoming e-mail messages with an IMAP e-mail server. IMAP is an e-mail protocol. You might be familiar with the e-mail protocol called POP3, which is very common with most Internet service providers (ISPs). IMAP works slightly differently, but it is similar to any other e-mail account that allows you to send and receive e-mail messages. The outgoing e-mail server is a Simple Mail Transfer Protocol (SMTP) server, the same type used by many ISPs. However, AOL requires authentication on their SMTP e-mail server. This requirement means that you must provide a user name and password — the same as your AOL screen name and password — before you send your e-mail message. You can save the user name and password in Outlook so that you enter the information just one time.

I exhausted a two hour on the talk assist with AOL. They walked me through setting up Outlook email one time over and the difficulty was not set. They after that recommended that I should maybe ask Microsoft if they had a few proposal s. The email address I entered is accurate in the setup. I have checked it a number of times. I had ended no changes to settings and like I said, Outlook email had been working just all right for approximately a years before this occurred. As for contact information, it does not theme if I type in the email address I wish to send to or make use of it from my contact list. The just thing I become aware of was while I utilized an email from my contact list, sent the email, I obtain the error message over, and after that the contact is erased from my list. I am not certain what else to endeavor. My account settings are accurate, but I have twice checked them again and again. I would be grateful for any help or additional thoughts to attempt. Let me be familiar with if you would like any additional setting information.
