POP3 connection - bad login

Hi,

I have enabled the Exchange POP3 Server service on my Exchange 2003 server. When I want to connect to this service I get the error message "bad login". What am I doing wrong? I must specify my Active Directory user/password for this connection or not?

Thx,
Dennieku

Hi all,

The problem is I have some oversea staff using pop3 connection to retrieve mails thru internet. The problem is this staff reported some mails sent by internal staff where the exchange mailserver located were not received.

I checked message tracker, and found that the above missing mails were indeed being locally delivered to her mailbox. I suspect mail may drop during pop3 connection, infected by virus, mistreated as junk mail etc.

How can I act on this issue? Does using secure pop3 connection will help?

Any suggestion is welcome!

Greetings.

The small business server version of exchange has a "pop3 connection
manager" under connectors.

regular exchange does not.

I'm trying to figure out how to pull mail from a remote pop3 server to the
exchange server. That is, Im tryint go get the exchange server to initiate
the pull from the remote pop3 server.

Any help is appreciated.
Thanks.
Steve

External users will use only smtp/pop3 connection to Exchange Server.

I dont won't create AD users with mailboxes.

Are there any other ways to resolve this problem?

Hey all,

Have 3 front end servers using Mirrosoft NLB and 10 back end servers
running exchange 2003 sp2 fully patched on win2k3. Getting the below error
in my event logs after I turn on logging on one of the front end servers for
pop3 connections. This started after I loaded a renewed SSL Cert. I've
restarted the server and the pop3 service. Any ideas?

"Connection refused because corresponding virtual server instance could not
be found or is not running. The error Code was 0x43."

I have setup an Exchange 2003 (Backend only) and everything is running great with MAPI and OWA!  However, I am attempting to POP3 into my exchange server and the server will not accept my credentials. 
 
To begin troubleshooting, I opened a telnet session and telnet to my server port 110.  I get a +OK  I look at my server manager POP3 Current Sessions and I see me attempting to log in (under user is says then it list out my IP address.
 
I type in my user id: user bsmith
Server responds +OK
 
I type in my password: pass abc123
Server responds –ERR Logon failure: unknown user name or bad password
 
These are the same credentials that I use for MAPI and OWA it those work just fine.  I even tried using my domain in the username (i.e. domain.orgbsmith) because that is how I have to login for OWA.
 
Thanks in advance for your assistance!

Hi,

I have 2 hub/client server running active/passive mode and 2 mailbox server as well. Now i have avaya client application that needs to connect to the exchange 2007 servers using POP3 connection to downlaod the mailbox (e-mail), however once we login using its credentials through telnet just to test, it shows this error.
Note: these servers resides in the same LAN. Is this caused by authentication issue? if so do you have any solutions?

Telnet CASServer 110
User Myaccount
Pass Mypass
ERR Command is not valid in this state

thanks.

When Itry to connect to pop3 I get

Logon failure: unknown user name or bad password.

I know that the password and user name was created correctly so I don't know
what could be causing this.

Hi! I've a POP3 connectivity issue. It's not possible for me to log in from a client machine to the POP3 Virtual Server for a Mailbox account in an specific domain.

My AD Forest is like this:
domain1.ws (forest root.) - Global Catalog
noc.domain1.ws (subdomain) - Global Catalog (This is the Domain where the Exchange Server 2003 exists).

I've created an account in "noc.domain1.ws" and everything went well:
name: test1
address: test1@noc.domain.ws
POP3: mail.domain.ws
SMTP: mail.domain.ws
User Name: test1@noc.domain.ws

When a create a mailbox-enabled user in the parent domain "domain1.ws" this user cannot log in to the POP3 Virtual Server:
name: test2
address: test2@domain.ws
POP3: mail.domain.ws
SMTP: mail.domain.ws
User Name: test2@domain.ws

Following a troubleshooting, I've logged into the POP3 Virtual Server via
Telnet, when I submit PASS, the Server answers:
"The specified directory service attribute or value does not exist"

Tried the same but enabling logging on the Exchange Server, and get in the Event Viewer: "authentication attempt has failed with error 0x200a"

I need help on this please!

Thanks a lot.
Beto.

Hey folks! I'm new to the board, and relatively new to Exchange2003.

Here's my situation: our company is moving to an internal Exchange2003 email server. We currently use an external email provider, from which our users get mail via POP3. Email clients supply their full email address (username@domain.com) and password to authenticate and fetch their mail.

Now, I have not been able to figure out whether we can CONTINUE authenticating our POP3 users using their email address rather than their Active Directory account name. Since we have a master email address/password list and can easily build all our accounts on our new server, I would MUCH prefer to let them use their email address to authenticate, as it would prevent us from having to help around 150 remote users reconfigure their accounts.

So: is there any way for a POP3 client to connect to POP3 on Exchange by supplying an email address+password rather than Active Directory account+password?

Thanks in advance... hopefully I'm not living a total pipe dream here.

When my users setup their Pop3/Imap accounts to connect to the server, they are required to enter their usernames in the following format:

username@domain.server.local

How do I avoid this so they only have to use their username?

Thanks,
Jeremy

POP3 connectoins accepted by server and then closing, but not log on to their accounts, as mentioned in event viewer. Not authorizing by server while with same ID can connect OWA and exchange client.

This is urgent. Please help.

I am having problems connecting to exchange using POP3/SSL (port 995). I
get the following error:A secure connection to the server could not be established. Account: 'Sue',
Server: 'EXCH', Protocol: POP3, Port: 995, Secure(SSL): Yes, Error Number:
0x800CCC1AI did read that you need to install IIS BEFORE installing Exchange. I'm not
sure if we did that since we've had both around for quite a long time. If
we didn't, would I have been able to see the POP3 protocol in Key Manager?
I installed the certificate in Key Manager and it doesn't show any problems
there.Any suggestions?? I could really use some help on this...Thanks in advance,
Sue

There was a problem logging onto your mail server. Your Password was
rejected. 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 exchange 2003 on 2000 server, installed 2008 server and E2k7, moved
the mailboxes.

So far 3 users attempting a POP3 connection have received this error above.

I have setup a new mailbox/user and dont get this error.
I then deleted one of the 3 problematic user + mailbox, added a new user
with same username + mailbox + email = no error.

Only appears to be the migrated mailboxes that have this error above when
connecting over Pop3. No problem using these accounts on the LAN/domain
directly using exchange accounts in outlook 2003/2007.

Can anyone help ?

User + pass all ok / checked.

Maybe some sort of authentication i need to run on all migrated mailboxes via the management shell.

Thanks
Scott

Hi there,

Currently when I try the Outlook auto-setup entering email account details for
an exchange server, this eventually connects, with no login prompt and then
gives POP3 connected message!

I have had Outlook Anywhere working to the extent where the connection can
be setup manually but then when account connected we see the OAB errors,
eg meaning basically the Autodiscover service isnt working..

Doing the Test-OutlookWebServices gives back a  (401) Unauthorized error
and goes no further.

I have tried the usual remove RPC over HTTPS component, then remove RPC
virtual dirs from IIS and finally add it all back in with reinstall of Outlook Anywhere
but this still fails..

Ive checked the URLs for all the services and externals/internals match, https:
shown on all. Ive checked the permissions on all virtual dirs and set correctly..

Really going round in circles here and thinking do I have to remove the CAS role
and reinstall now? Any suggestions?

Thanks

I just applied all the updates to Exchange 2003 on my SBS server (I am still amazed they don't happen automatically) including the IMF.

Since upgrading, the spam has decreased (YAY) but the POP3 server is innaccessible from inside my office (192.168.x.x).  Exchange just gives "Connection Refused".

Any ideas?

I am currently having a problem with certain users trying to retrieve
their mail from the exchange server by using POP3. When the users
login to the network with their username/password everything is fine
but when they enter the same details for the POP3 account they get
rejected. Many users can use POP3 to retrieve their mail but it's
mostly the new users that can't. I have checked their accounts in AD
and they are allowed to use POP3 in the "Exchange Adavanced" settings.
I have heard that the "private information store" may be corrupt.

Can anyome help me with this matter please ?

If it helps, i have conected to the POP3 server on port 110 through
telnet and logged on that way and it reported that the users were
currently disabled but when I checked in AD this wasn't the case.

Many thanks in advance

I am trying to connect internal LAN clients to my exchange server via pop3
connection and running into a problem.
I have a few users that travel and I want to set up their portable machines
to connect via pop3 so they can seamlessly connect whether from the internal
LAN or externally.
I can successfully connect if they join the domain and choose an exchange
connection and can even set up an exchange connection without joining the
domain. Externally they can connect to the pop3 connection just fine however
when on the internal LAN they are prompted for user/pass and will not accept
any variation of account info.
For username I've tried user, user@domain, domainuser, and
domainuseralias with no luck.

Server is windows server 2003 with exchange 2003 sp1.
All updates have been performed.
The pop 3 service is enabled and functions ok for external connections.
Client is windows XP pro with office 2003.
Mail server is being set to mail.domain.com which successfully resolves
internally and externally to the proper ip address.
I can tell that the client is connecting to the server because it instantly
rejects the user/pass unless I point the mail.domain.com to an invalid ip,
at which point it times out.

Any ideas how I can get this working?

I'm having a problem connecting to my Exchange server to download messages
via POP3. MANPI, IMAP, HTTTP, RPC/HTTP all work fine.
When connecting via Outlook Express I get the message:

-----------
Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Account: 'mail.mydomain.com', Server: '10.1.1.2', Protocol:
POP3, Port: 111, Secure(SSL): No, Error Number: 0x800CCC0F
-----------

I have verified that POP3 is running, and is set for use Any Available IP.
I can telnet to the server on port 110, but when I hit key, I get dumped
right back to a command prompt.
I saw an article about how this will happen if IIS is set to enable
bandwidth throttling, but my server is not. I have even set and unset
throttling just to force a change. I've created a new POP3 virtual server.
It's not a firewall issue, since there is no firewall between me and the
server. If I run perfmon, I can see the amount of POP3 connections grow each
time I try, however no email ever gets downloaded. I have looked into the
user accounts to make sure POP3 is enabled for them.

I'm out of ideas at this point.

Hi,

I have a customer who's running several email domains on the same Exchange 2000 server, but they're small and have ONLY one Windows Domain (say, company.local). POP3 access from outside is no problem by using user@company.local as POP3 user account. I'm just wondering if there is another way to let them use email account i.e. user@othercompany.com to get authenticated when logging using POP3 connection from outside?

I appreciate that anyone has any idea, OR just simply tell me NO, impossible... Thanks in advance!

Hello all

I am having a problem setting up Outlook 2010 to connect to Exchange 2010 using POP3/SMTP. Actually, the real issue is a PHP script sending email which is having difficulty sending email via SMTP, so I thought, first let me test via a mail client.

POP3 is ok, Exchange server is fine. Mapi, OWA all fine. Everyone is using it just great. Receive connectors are fine.

In Outlook 2010 (same as the PHP script), I setup the correct server and login details, but when i test Pop3 connects fine, but SMTP keeps asking me for username/password. It rejects whatever I put in. I have tried , , auto, SSL, TLS (we do have a valid SSL certificate on our server), but it keeps asking for user name and password saying (Your mail server rejected your login. Verify your username and password for this account inaccount settings).

I have ticked and unticked everything in this Outlook and have ran out of ideas. Can anyone suggest anything? I never had this problem with Exchange 2007 and we have just moved to Exchange 2010.

I look forward to any of your ideas.

Regards

Nima

I am stumped on this one. I have a 2000 domain that I setup as workgroup.domain.com. Obviously I don't want my emails to read user@workgroup.domain.com but rather user@domain.com. I setup a recipient policy for
domain.com. I can connect via Outlook while I am connected to my network. The problem comes in when I try to setup a POP3 connection. I even tested it from within the network and I can not connect. The error I get says bad username or password. As a test I setup a new account but left it as workgroup.domain.com and I was able to get in with no problem. Then I change the account to domain.com and it gives me the error. Does anyone have any ideas I can try. Any help is greatly appreciated.
