Hi, Can someone please help me?I have a pop3 connector setup on our exchange(2007) which use to work like a dream.Now all of a sudden my pop 3 clients are unable to recieve their emails on port 110.However,if I check the ssl box on the client's account settings,it works.I have made sure that Integrated Windows authentication and secure logon is uncheked on the Authentication tab under POP 3 propreties on the exchange.Some of my clients need to use non-ssl(110).How is this possible

Hi Start verbose POP3 logging and see if you can find anything related http://technet.microsoft.com/en-us/library/aa997690.aspx Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

Hello, Pop3 is not working => Checked on the Exchange server 2007 Exchange management console --> Server Configuration --> Client Access --> POP3 properties and found à Plain text logon (Basic authentication) => On Default receive connector --- Under Authentication --> unchecked the Offer Basic authentication only after starting TLS => Checked the user POP3 profile setting and checked the box -- My server required authentication & Leave a copy on the sever => After that we restarted the Transport & POP3 service on the server It will fix the issue EXCHANGE2010, MCSE, MCTS, MCSA MESSAGING, CCNA & GNIIT

Hi Thanks for your reply. I made the changes you suggested and unfortunately it did not work.This is really becoming a head scratcher as I have spoken to numerous exchange engineers and they too dont know of a solution. Thanks

Hello M.H Smith, If you followed Steps provided by me (PKT_), it should work. Are you trying to configure the POP3 profile for Admin accoount, if yes then it will not work. Please let us know. EXCHANGE2010, MCSE, MCTS, MCSA MESSAGING, CCNA & GNIIT
