Internal POP3 Server with AD integration
Posted on 2012-04-02
Here is my setup: I have a few VMWare Servers in my lab, one AD, single domain. One of the servers have POP3 Service enabled and I have 2 client VMs, where I want to run Outlook using the POP3 mailboxes. (I tried Exchange previously but it is unnecessary for my environment)
2 client VMs: (one has Win XP with Outlook 2007 and one has Win 7 with Outlook 2007), one POP3 service enabled Server and a seperate AD and DNS server. None of them has access to internet and all of them are on the same subnet. There is no visible issues: only the users my client VMs have cannot send/receive emails with the POP3 accounts.
There was Exchange Server before and I completely removed it from the lab setup. The new POP3 has AD integration, the mailboxes are correctly setup. No firewall or AV is enabled. The client PCs can telnet the POP3 Server on port 110 and 25 (for SMTP).
When I setup the email account on Outlook and test the account, logon to incoming mail server (POP3) step works however 'Send test email message' fails.
I wanted to make sure there was not an issue with my mail user, that's why I brought in the second Client VM (Win 7) with a new user but the issue is the same on that one also.
When I create emails, the emails are stuck at Outbox with error code 0x8000CCC0f. I've googled the issue and read MS notes. None of those notes are applicable to my case.
I need some ideas and guidance on how I can troubleshoot the issue. Is not there any logs or some kind of reference that shows in depth information?
Thanks in advance
