Hello, I installed Exchange 2010 Sp1 and I want to use pop3. When I configure the clients pointing to my cas server with port 110 and 25. It asks me the authentication. I am new to exchange so please bare with me and show me step by step.

Hello, are these clients inside or outside your network? Why do you want to use POP3? Greetings, Toni

no they all are inside outlook prompt for password and I have all the information correctly filled

Hello, have you tried creating a MAPI profile in Outlook instead of a POP3 profile? Since your clients are inside your network (and I assume they're joined into your domain) this shouldn't be a problem and it'd be better than POP3 (no plain text auth etc.). Greetings, Toni

I am new to exchange so please bare with me and show me step by step. How you configure the client depends on the client you're using. The authentication credential might be "<ADDomain>\<ADAccount>\<Alias>", or it may be the UPN of the AD user. The passwords is, well, the password. If you're using Outlook as the e-mail client then you really should lose the POP protocol and usr RPC or RPC-over-HTTPS. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

I use all the clients which includes some pop clients as well and my high management team member says he is much more comfortable with it and I am forced to do it. Do I have to chage some thing in Authemtication Mechanism on the pop settings like clear text ?

Hi, Step 1: 1. Open EMC, expand to Server Confirguation->Client Access, highlight the your CAS server which has POP serivce enabled. 2. In POP3 and IMAP4 tab, right click POP3 and choose properties. 3. In authentication tab, select "Plain test logon (Basic Authentication)". 4. Restart Microsoft Exchange POP3 service. Step 2: On outlook client, configure the pop account. In Internet E-mail Settings page, check the box "Remeber password".

Thanks Glen I will check and let you know

Thanks Glen I managed to download the messages as per your recommendation. Now I am not able to send email using port 25 I dont have any firewalls or AV configured on my lan

Hi, What's error you receive when trying to send the message? Please check if the "My outing server (SMTP) requires authentication" is enabled on your POP profile: 1. Open Mail in control panel. 2. Click your pop3 account and choose E-mail accounts. Click Change. 3. In "Internet E-mail Settings" page, click More settings. 4. In Outgoing server tab, check the option "My outgoing server (SMTP) requires authentication". If the issue persists, please use another computer to configure the pop3 account by outlook.

Dont you think I have to change any thing in the Receive Connectors ?

No You don't have to do any thing on the receive connectors leave it as it is. Thankshttp://www.virmansec.com/blogs/skhairuddin
