[Tim Callaghan]

On Windows mail whenever i click on "send/recieve", it comes up with a request for my username and password. After typing this in it will the request will come up again. Canceling out of this loop makes it come up with the following message
Account: 'pop.wanadoo.co.uk', Server: 'pop.wanadoo.co.uk', Protocol: POP3, Server Response: ' Disconnect because authentication to back server is too long', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC92
Can anyone help me!?

funny I am getting the samew thing, for the past two days now, I can't get
my mail either, same exact error messages, I have even deleated my accounts
and reentered them still doesen't work....

I can guarantee that you will have future problems with Windows Mail
if you keep Norton on your PC.

Get rid of Norton before you get a bigger issue. Small warning today

I had the -exact same- problem and do not use Norton but use Webroot.
So after reading the postings here, I had Webroot do a complete virus scan, then restarted my computer and now Windows Mail works fine.

Yeah, I should have learnt. I've had problems with norton before but it's always fixed itself (eventually)

Ok, now i'm getting these error messages. Is it anything to do with the antivirus (Norton) and if so what can I do about it?

Account: 'pop.wanadoo.co.uk', Server: 'pop.wanadoo.co.uk', Protocol: POP3, Server Response: '-ERR [IN-USE] Unable to lock maildrop', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC92

(and if it's not the antivirus what can I do about it?!)

0x800CCC90 = POP3_RESPONSE_ERROR = Client response invalid.
0x800CCC92 = POP3_INVALID_PASSWORD = Password not valid for account.

Double check to make sure that your password is entered correctly in
your email account settings. (Tools - Accounts) It would not hurt to
double check you account settings with your email provider's support
webpage on how to setup a email acconut in Windows Mail or Outlook
Express. They both use the same settings.

Hope this helps

Change the Password?

From what I have read, there appears to be more than one cause of the
0x800CCC90/0x800CCC92 error message and, hence, more than one fix. The
following might be of help to some people.

After a recent weekend when my web-hosting provider carried out system
maintenance, I started getting the 0x800CCC90/0x800CCC92 error message
on attempting to retrieve mail. This happened on a laptop running Vista
using Windows Mail, but not on two desktops running XP using Outlook
Express.

Tried disabling email virus checking.
Tried uninstalling/re-installing TCP/IP.
Payed money for two registry fixing-programs, one of which explictly
claimed to fix the 0x800CCC90 error.
Tried re-installing Windows.
Tried everythig else I could think of until I finally tried a different
mail program (Mozilla Thunderbird).
The new mail program had the same problem, but gave a more explicit
error message; namely, that it was the mail-receipt password that was
rejected. Changing to a completely different password fixed the problem.
My problem is fixed, but not explained. The old password was accepted
before the maintenance, and was still accepted afterwards when sent from
computers running XP. What change can have occurred to create a problem
for a Vista laptop?

I am using Avast.

Deleting and recreating the account was one of the first things I
tried; although I can't remember whether I re-started Windows Mail in
between.

Chances are, your antivirus corrupted that account when you had
email scanning enabled. Also, for some antivirus programs, just
disabling email scanning is not sufficient. Which antivirus was it?
One thing you should have tried is delete the account, restart
Windows Mail, then recreate that account.

Avast antivirus has a problematic email scanning module
that can cause problems with Windows Mail even when
scanning is disabled. Uninstall it, then reinstall, but
select 'custom' install, which then allows you to unselect
installing its troublesome email scanning module.

>Tried disabling email virus checking

Uninstall your Anti Virus and then re-install it without the email integration
(scanning) option. Just by disabling the AV scanning might not work and or take
effect (it does not on most)

Thanks, Gary and Peter, for the information on turning off email virus
checking effectively.

I was going to check this out, and changed the email password back to
the one which gave trouble. However, it is now accepted; no 0x800CCC90
error.

So, I can't do any testing until the problem arises again; but I will
be better prepared when that does happen, thanks.

In the popoup window that asks you to verify or confirm your account name and password, enter only the user name WITHOUT @ and what follows,
and your password--it worked for me.

Try entering your USERNAME without the "@ (and what follows).

Regarding your antivirus choice, you "jumped from the fire to the frying
pan" !! McAfee can be every bit as problematic as Norton !! Windows
Security Essentials would have been a better choice.

I am having the same error numbers appear. I have tried my username with and
without the @btconnect.com and have also deleted the account and started up
again and entered a new account. I have no antivirus running. The complete
error message is:-
There was a problem logging onto your mail server. Your Password was
rejected. Account: 'pop3.btconnect.com', Server: 'pop3.btconnect.com',
Protocol: POP3, Server Response: '-ERR Logon failure: unknown user name or
bad password.', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error
Number: 0x800CCC92

I had exactly the same problem, actually i still have the problem, I tried all the things suggested here, aslo spent an hour on the phone to my service provider who ended up saying it must be a microsoft problem not us... finally by accident I have at least managed to send / recieve emails... before, the window would continualy pop up asking for username and pasword, but after I had input the corect details is popped up again aking the same. On that pop up there was a checked box, saying remember my credentials, when I unchecked the box and put my details in, it accepted it and my emails worked normally. But everytime I open my email program, it asks me again. So the problem hasn't really gone away, but at least I can use my email again.

I have however tried all of those things...
I already run the latest windows mail program, I have uninstalled Norton anti-virus comletely, and because I can't leave myself unpretected I've just loaded up a new 12 month contract with McAfee. The pop ups on my email were still happening while there was no antivirus program running at all on my laptop. I know I'm using the correct username / password as the email webpage accepts them and I can read my mail there. I am really stumped. There must be someone somewhere who is either responsible for the error or knows what is responsible for the error on all our computers!? Microsoft? how do you get in touch with them?

Test your password by logging in to your webmail:
http://bt.yahoo.com
If that works, it proves you have the correct username and password.

Has an antivirus program like Norton or McAfee ever been installed on
that PC? Most new PCs come with a trial version of those.
Is any other third party security program running?

Without an antivirus program, your system could easily be invaded and your
sensitive information, such as email account and password, could be obtained
by anyone that wants to do harm or just play around.

First, test your password by logging in to your provider's webmail.
If that works, it proves you have the correct username and password.
A likely reason for the username/password failing is account corruption.
One thing you should try as a possible quick fix is to delete that corrupted
mail account, restart Windows Mail, then recreate that account.

If that doesn't fix it, more drastic measures will have to be taken.
Which antivirus are you running?
As a minimum, email scanning in the antivirus must be turned off,
although that may not be sufficient to eliminate all bad effects.
In a worst case scenario, your antivirus may need to be uninstalled.

If turning off the email scanning function does not resolve your problem,
consider upgrading to Windows Live Mail, because it is less prone to
suffering bad effects from overly aggressive antivirus programs.

Why did you get McAfee without checking with the experts first?
There are other antivirus programs that are much more compatible
with Windows Mail.

If you don't want to get rid of McAfee, your best remaining option
is to upgrade to Windows Live Mail, because it is less prone to
suffering bad effects from overly aggressive antivirus programs.

1st one question:

Will Windows Live One Care affect this?

Ok, I have did everything in these posts NOTHING works.. I have tried Thunderbird, Windows Mail and nothing works... 3 of us have been without email for a week now... I have used Reg Boost to clean the registry on all accounts.

What is the fix for this?

[mrsb7333]

I had the same problem. I tried everything suggested on all of the posts on this website relatiing to this problem, as well as a lot of googling. I finally found an easy fix. My ISP is Comcast. For the Incoming server address, I had been using "mail.comcast.net", which Comcast said to use, and has always worked (until now).

The Microsoft website http://windows.microsoft.com/en-US/w...tart-to-finish
said to use the following for the Incoming server: pop.myisp.com (or imap.myisp.com, if they use an IMAP server). I wasn't too hopeful that it would make a difference since nothing else worked, but for ha ha's I changed mail.comcast.net to pop.comcast.net, and now both Incoming and Outgoing servers work fine.

Hope this works for anyone else experience this problem.

I had this problem, too. Repeatedly asked to log in, with this error code. Simple problem = I was putting in my user name WITH the "@whatever.net". Once I put in user name WITHOUT this, problem went away.

We were seeing this error on Outlook Express clients when they had a smartphone that also checked e-mail. In this case we were running a mailenable mail server on W2K3. The outlook client would work fine until the smartphone checked e-mail, then we get the errors above along with a password request over and over.

Some troubleshooting revealed the mail server as the culprit. Recycling it fixed the problem everytime on the Outlook client. We found that setting the timeout for remote mail servers down to 180 seconds from the default 1000 in mail enable fixed the problem. Both of these phones were on the sprint pcs network. Not sure on the process used by the smartphones to check e-mail but they must act as a forwarding server somehow, rather than a client.
