Outlook 2007 – cannot send/receive email on any computers

Microsoft Outlook error messages
Horrendous problem with Outlook 2007 – have tried everything but nothing has fixed it so far. I have 3 machines running Ultimate, Vista Home and XP SP1. It’s the same on all. It was all OK until 3 days ago and suddenly all had the same problem – when I try to sync I get a window asking me to enter my password (which is already saved in Outlook, of course) but it will neither save it nor access the server. I get the error message: Receiving' reported error (0x800CCC92) : 'Your e-mail server rejected your login. Verify your user name and password in your account properties. Under Tools, click E-mail accounts. The server responded: -ERR invalid user name or password.' I know this is common because I can see it everywhere, but none of the solutions work. Steps taken so far: 1. Changed my profile and deleted the old one 2. Deleted my account and set it up again from scratch. I’ve done this from Control Panel/Mail without Outlook even running – problem is, it won’t even set it up automatically – I get this message (even when I set it up manually): “Log onto incoming mail server (POP3): The operation timed out waiting for a response from the receiving POP server. If you continue to receive this message, contact your server administrator or ISP.” 3. Being Gmail, I have tried to set it up with both POP and IMAP but no difference 4. I use Spybot, Adaware and Spywareblaster as well as Avast antivirus, which I have disabled, to no avail. 5. I can access my Gmail account through the web normally PLEASE help – hours spent with no progress. THANK YOU.

Thanks. We'll let you know when a new response is added.

This reply will NOT fix the problem, it will however, give you some additional information to do so. It looks from your problem description like some network diagnostics are in order.

Get a copy of wireshark (formerly known as ethereal) from www.wireshark.org and install it on one of the problem machines. Make sure you also get the winpcap package as well.

You do NOT need extensive protocol experience for this one – you’ll most likely just be looking at the summary.

Start wireshark on the affected machine, and then select the active network interface from the Capture menu.

Go run Outlook and test for the problem USING THE POP Protocol. Once it has occurred, then stop the Wireshark capture (Capture -> Stop).

Go back to wireshark and browse down the list for the POP login, password and server response.

Hopefully, you will see in this list some indication of the base problem.

Write back with whatever you find.

Good Luck,

    Another thing to try, on the XP system, setup your email on Outlook Express and see if ti will send/receive. I have not had any problems using Outlook 2007. This will at least point to if it's Outlook 2007 or some sort of server credential issues.

    I had this same problem before with 2003 and i put most of the problem down to connection issues because i ruled out everthing else too. I think you should check with your ISP about service pack issues especially with vista and i am interested to find out how you get with this. Good Luck Debbie
