Outlook 2000 fails to send SMTP - Error 530 (0x800ccc78 & 0f)

Hi, guys and Gurus :)  I know this has been asked about a lot, but I didn't find much help in the old Q's.
Outlook 2000, Win 98 FE, home office (no LAN) 56K dialup direct line, disabled firewall, disabled virus scan.  Yeah old computer!  ISP has recently converted to smtp authentication server.  Now the outlook client won't send.  Been through the ISP tech help, changed settings dozens of times.  "Server requires auth..." checked.  Secure login unchecked. Tried both "use incoming settings" and specified username and pwd.  Tried port 25 and 587.  I've deleted all mail accounts and replaced them.  The error still occurs both in Outlook and Outlook Express.  It appears that Outlook is not sending UserID to the smtp server.  I made sure that the "Prompt for password" was enabled, but smtp never offered a prompt before kicking me off, although the POP did.  Outlook and DUN have been removed and reinstalled.  I've installed a new modem just in case.  I searched the Microsoft KB and everything suggested I've tried fails the same way.  I also took a look at the registry settings for the account and everything seems in order.

Errors were initially 0x800ccc78 and have now changed to 0x800ccc0f.  Both produce server errors of 530.  Phone line is clean, dos prompt PING to the smtp server works fine with no lost packets.  ISP basic connections are fast (for dial-up) and strong.

BTW, I tried my new computer with XP Pro/Outlook 2003 and got the same results over the same line and ISP.  Anyone have any ideas about this one?

Greetings, tomk !

You have done alot of troubleshooting.  See if these steps will help:

1. Register an important send/receive library file.  Go to Start > Run and type regsvr32 inetcomm.dll

2. Check if other programs running in the background is interfering. Disable one at a time the Firewall, antispyware, antispam, and all Norton programs.

3. In the account settings, Advanced settings, change the server timeout time from 1 min to 5 min

4. Check your setup with another POP3 email service, like Gmail or BlueHome.

5.  Check with email provider Tech Support to determine if server is having trouble.

Best wishes!

Hi, War1, thanks for the suggestions.

1.  Don't know anything about doing that.  More info please.  What does that do and what is a send/receive library file?

2.  I've done that repeatedly.  Norton e-mail settings, firewall et. al.  No changes observed.  I even deleted the programs (since re-installed).  It doesn't seem to make any difference.  Good thought, though.

3.  Haven't tried that, but I doubt it will change anything since I get a "Connectiong to server" and then an almost immediate kick off and a server error report.  At this point though, anything is worth a try.  (I have already tried some pretty wierd stuff!)

4.  Well I can send from the web OK.  So how do you set up a smtp server for another site where you don't have an e-mail account?  Explain how-to a little more here, please.

5.  After about 5 total hours on the phone with them to no avail, I bet they don't want to hear from me anymore!  LOL

Good suggestions.  I'll see what else.  Please get back to me on this.

Good luck as usual.  TomK
1. This suggestion registers an criticial library file for sending, without which send/receive will not work.

2. Do you have antispam or antispyware software running? These can slow Outlook same as antivirus.

4. Go to Bluehome website and get a free account.

Set up POP3 and SMTP access via Outlook.  Try to send from this service.  If you are successful in sending, then the problem is your ISP.

Just to get back to you war1.

1. registration was sucessful, but error remains

2. no, it's all disabled.

4. I have always been able to send via web-based mail.

isp tech sugested maxing out the updates on my old Win98.  The isp tech set my account up on one of their in-house W98 systems and all worked normally.

Next troubleshooting steps:  I have a nearly virgin notebook with WinXP Pro.  I'm going to try to set it up and see if it will generate the same error.  I also am going to see if my other XP system will still generate the error.  Stay tuned, I won't abandon the question.

good luck as usual.  TomK

Problem Corrected.  Apparently Outlook Express (the underlying program for Outlook) was fouled up or too old to respond properly.  I downloaded and installed IExplorer 6 SP1 (which includes updates to Outlook Express) and that solved the problem.  I don't have a specific resolution except for updating the programs.

Thanks for your help, war1, if I owe points, I'll be happy to pay.  Thanks for the forum.

good luck as usual.  TomK.

Glad the problem is solved. Outlook Express should not affect Outlook. But downloading a new version of OE could have register some important send files for Outlook.

war1, the Microsoft KB article said that Outlook relies heavily on Express to work correctly (and of course you're right about OE).  I now have OE 6 which is significantly different from my W98 original, so you're probably right again.  :)  Thanks again.  TomK
