Can't connect to POP3 server

Totally baffled by this problem.

I use Outlook to connect to 2 different POP3 servers. When I am working from home everything works just fine, however for the last few days I have been unable to connect to either of the POP3 servers from my work LAN.

The message I get is "reported error(0x800CCC0F): The connection to the server was interrupted". This is identical for both the POP3 servers."

This has previously been working fine, and the only thing that I can think has changed would be down to Windows (Vista) updates.

Any ideas?

Thanks in advance.

Cant connect to Exchange server

I have a box that is not part of my employer's domain. When I fired
up Outlook this week it has stopped being able to connect to the
exchange server. It used to prompt me for authentication
(username/password) but now it doesn't. The last email in Outlook on
this system was Jan 4.

When I tried blowing away my profile and set up a new one I get an
immediate response about Outlook not being able to connect to the
server.

Someone told me that they remember something like this where Outlook
is sending the authentication info when it shouldn't and there was
some way to "reset" Outlook not to send the authentication info.
Again, I've checked the "always prompt for pasword" in Outlook but it
never does.

Not all the time,but most of the time I get "unable to connect to pop3
server". Is there some update that I have not gotten. windows XP office 2000

HI

I have installed exchange 2007 with SP1 on windows 2003 X64 with Sp2. I want that all of my clients will use POP3 settings to connect to Exchange server, I have two questions in this regard.
1.) I have started the POP3 service on exchange server, But whenever i try to Connect to exchange server using POP3 settings, It prompts for password, I have provide correct password, But it never connects to exchange server and shows the error
"Outlook could not connect to incoming POP3 mail server because server did not accept your username and password."

ALthough I am able to connect to server using OWA and able to send and receive msgs.
POP3 settings are enabled in the user account in Active directory.
I am able to telnet myserver.domain.com 110 and it responds with "OK Microsoft Exchange pop3 service is ready"

2.) My second question is if i would be (Should be) able to connect to Exchange server using POP3 settings. How could i store the emails on the server. so that in case client computer goes corrupted.All the emails will be available as they are on the server.

Any Help

hi i am having a little problem when i try to connect to my exchange
server from any client on lan , says cant find exchange server , but
if i connect from wan - its fine

i can connect to other services on the mail server , ie folders and
proxy server

i wonder if its a dns / routing issue ?

when i ping the server name from an internal client it shows that the
ipaddress is the external ip address for our server rather than the
internal address ?

where would this be configured ?

the server is nt4 sp6 and exchange is 5.5

this is i think a multi honed system , which unfortunatly i did not
setup and to be honset - havent got my head around how this all works.

the server did say that it had a problem on the external (wan) network
card but i re booted the server and it seems ok ?

could the server have reconfigured something because or the netcard
failure ?

please help if you need more info i am happy to provide !!

thanks in advance

I have setup 2 new Dell computers, both running Windows XP Pro and Office
2007 that experience the same problem. After correctly configuring both the
local Exchange and remote POP3 accounts (using the same configuration info as
used on similar machines running Outook 2003 that work flawlessly), a "Send
and Recieve" results in an error 0x80042108 "Outlook cannot connect to your
incoming POP3 e-mail server".

Both computers have all MS Updates installed and are current with pertinent
patches. The dreaded Symantec Personal Firewall feature has been disabled,
as has the Windows Firewall during testing. All other functions work as they
should.

The same users logged into other workstations using the identical user
account info can access both Exchange and POP3 mail, both sending and
recieving. Those users are temporarily using their old computers until I can
get a handle on this problem. They can successfully retrieve the messages
sent from the new Outlook 2007-based machines. My only other experience with
Outlook 2007 has so far been on machines running Vista Business Edition
without any problems.

Any ideas? I'm scratchin' my head over this one!

Hello

I am using Outlook XP to access my POP3 email account. It has been
working fine for about 2 years but all of a sudden, I'm getting error
messages saying that it can't access the server.

I know that the service is working fine because I can use a web-based
service to connect to it. I haven't installed anything new on my
machine and my web connection hasn't changed.

Any idea?

TIA

I have an exchange server with about 60 users,using win 95/98/2k. All of these were setup fine except for one windows 2000 machine running outlook 2k.It cant connect to the exchange server,even when all the settings are exactly the same as other win2k machines that can connect.Some critical s/w is installed so i cant wipe machine or reinstall windows.Any ideas?I can see the machine on the network, but cannot connect to exchange server,even to check name.
Help!
reply to probert@stjohnshospital.ie if possible please.

Environment - Windows 2k Srv Sp 3, Exchange 2k Srv Sp3 with rollup.

Problem -
I cannot connect using the Microsoft Exchange account type in Outlook. It gives an error message "Cannot find the username in the directory". I also found an article from MS, and I have had to use the domainusermailbox to login using pop3 account. That is the only way to connect to the server right now - pop3, and you don't get all of the public folders and stuff.

I did replace the default Global Address List with a custom one excluding system accounts.

Any insight would be helpful.

Thanks,
Brent

When I try and connect to the exchange server on the LAN using Outlook and exchange account, it says the server can not be found, I can ping the server no problem. The server also runs our DHCP and every machine is connection and get ting an address from the server.

When I try and connect with POP3 I get the following error:

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 have triple checked the account name, and reset the account password twice, just to make sure those where correct. I get a similar error when I try and connect with IMAP.

I have all of those protocal configured on the server.

The only way I can connect to the server is will HTTP or Web Access.

I tried to Telnet the server I get the following message:
+OK Microsoft Exchange 2000 POP3 server version 6.0.5762.3
> ready.

I try and log on and get errors.

when I quit I get the following message:
+OK Microsoft Exchange 2000 POP3 server version 6.0.5762.3 signing off

I had this server working a couple weeks ago no problems, when I changed the IP from the testing numbers to a live public address so I could begin testing on the internet I was no longer able to connect to the server.

Anyone have any ideas?

Thank you.

I am trying to setup pop3/imap on my Exchange Server 2003.

I can send via smtp through my pop3 program, but can't login to the pop3 server. Outlook works fine via Exchange, but can't access pop3 or imap.

I am running SBS 2003, and the Exchange Server side of things works nicely, and even OWA works through the Remote Webplace connection.

When I go into Outlook it keeps prompting me for my username and password. I can access OWA with my username and password, but using Pop3/Imap I can't access. I am using both the domain username/password, and the email address username.

I have actually tested the connection - and it works. I can telnet to port 110 and 143.

I am using correct username/password. Still saying

Task '- Receiving' reported error (0x800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).'

This happens when I am inside and outside the firewall (linksys router with ports 25 and 110 open).

Any help would be appreciated!

Thanks in advance,

Jeremy

I've noticed a curiosity with OL2007 final:

Upon OL startup (and only then), and only when there's mail waiting, the
usual automatic delivery of POP3 doesn't happen. Instead this shows in the
lower-right part of Outlook almost immediately (it's not timing out since
it's so quick):

Task 'Main - Receiving' reported error (0x800CCC0F) : 'The connection to the
server was interrupted. If this problem continues, contact your server
administrator or Internet service provider (ISP).'

However, if I then immediately hit F5 to deliver, the mail comes right down
(I'm on a fast connection). Furthermore, it'll never happen again until the
next time I start OL with mail waiting. Dozens of automatic deliveries a day
work fine.

Looking it up, I came here (http://support.microsoft.com/kb/813514), but
I've accounted for those things (no AV, firewall, etc), and nothing's
changed from my previous setup a day ago anyway (B2TR, and before that B2),
which didn't show the problem.

Anyone else seeing this? It's pretty minor, but it appears that OL is
getting ahead of itself when started up.

Using XP Pro SP2 and Outlook 2003. My exchange server is not at the office I
work at, its at another location. I never have any trouble connecting to it
while in the office, logged into the local domain. However I never seem to
be able to connect to it outside the office, so I thought at first it had
something to do with me being logged into the domain. But I happened to be
at a remote location one day, opened up Outlook and low and behold it
connected. So it only works in the office and at this one remote site,
nowhere else. The only thing in common with the two sites is they use the
same DNS servers. So now Im thinking that must be the key. I get home one
night and change my DNS settings to match my work DNS settings, open up
outlook and ....damn...no such luck. So now Im back to being stumped.
Someone please offer me some advice!!

TIA

This has just started to happen today. Mail server is working ok, have tried

Windows 2000 SP4 Outlook 2003 fully patched

I have two systems running Outlook, both connect to a private network
via Cisco VPN client software. Machine A is part of my employer's
domain. Machine B is part of my local workgroup.

This week I fired up Outlook on machine B and discovered that it could
not connect to the Echange server. The last time I did this
(according the Outlook's Inbox) was Jan 4.

When using Outlook on machine B via the VPN I used to get propmpted
for my credentials (username, password, domain). Now I do not get
prompted for my credentials.

Outlook's status bar shows "Loading" then immediately "All folders up
to date". The right side shows "Disconnected". Outlook exhibits this
same behavior when the VPN connection is not active.

When trying "Send/Receive" Outlook immediately shows the error "The
server is not available" code 0x8004011D (again same behavior when VPN
is not connected).

When connected to the VPN my Exchange server name does resolve to an
IP and I can ping the IP through the VPN.

I have tried changing some of Outlook's properties such as "always
prompt for username/password" (still never get prompted) as well as
password authentication scheme.

I do not have any problems using Outlook via the VPN on machine A.
Other employees that have machines not on the domain report that they
can connect to Exchange.

We're using Outlook 2003 to receive mail from our provider's pop3 server.
Since we have so many workstations, instead of entering the mail server's IP
address into each workstation's Outlook configuration, we simply use the name
"pop3" and then configure our Windows Server 2003 DNS to have the name "pop3"
to point to the provider's mail server's IP. So this has been working for
years without problems.

Our provider recently upgraded their mail servers, which means, the IP
address had changed. So I changed the DNS entry for "pop3" to point to the
new IP address.

Now, when I try to check my mail on my workstation, I don't get my new
emails. When I enter the IP address directly into my Outlook settings, it
works and I'm able to receive new emails. I can do an nslookup pop3 and the
correct IP address is returned. But when I revert back to using "pop3", I
don't get new mails again. For some reason, Outlook doesn't like the name,
but accepts the IP address.

I have tried using ipconfig /flushdns, and restarting Outlook, but it didn't
solve the problem.

Any help would be appreciated. Thanks!

Hello,

I have a web mail service and i use outlook express to download my mesasages

I have been using OE for sometime now until 4 days ago. i thought it was a
problem with my machine and i did a system restore.

Afer setting up OE it keep getting the the following message

"The connection to the server has failed" with the following details
shown below

Configuration:
Account: Customer Service(Niko Consult)
Server: mail.nikoconsult.com
User name:

I have been pulling my hair out trying to migrate the mail settings for some
of the people in my office from POP3 to IMAP. If I had my way, I would ditch
Outlook 2003 and go with Thunderbird. I have never been a big fan of
Outlook, but I am *really* starting to hate it now.

The problem that I am having is that for most of the machines I am trying to
migrate I can not get connected to the IMAP server. I enter all of the
correct connection details, but then I get an error like:

Task 'Checking for new mail in subscribed folders on Work.' reported error
(0x800CCC0E) : 'Outlook is unable to download folder (null) from the IMAP
e-mail server for account Work. Error: Unable to connect to the server. If
you continue to receive this message, contact your server administrator or
Internet service provider (ISP).'

Task 'Work: Folder:Inbox Check for new mail.' reported error (0x800CCC0E) :
'Outlook is unable to download folder Inbox from the IMAP e-mail server for
account Work. Error: Unable to connect to the server. If you continue to
receive this message, contact your server administrator or Internet service
provider (ISP).'

The error seems to be somewhat random. For instance, on my personal
machine, I setup 3 different accounts for testing. One would always work
perfectly the other two would always fail. Then, today, for no apparent
reason all 3 worked. I tried on a new machine where outlook had never been
used - using the same account settings that had always worked on my personal
machine - it always fails.

When I connect from Thunderbird, KMail or even telnet it works perfectly.
From Outlook... No go. I have been scouring internet sites searching for a
fix, but so far nothing I have tried has brought me any luck. Some of the
things that have been recommended include:

- Not using SSL (no good)
- Changing the 'Root Folder Path' (doesn't help and creates other problems)
- Creating an outlook 97 PST file (no good)
- Checking for error 4226 in the event viewer (not found)
- I disabled the antivirus programs on the machine (no good)

I finally resorted to sticking a packet sniffer on the network. Overview
of what happens:

- Outlook connects
- IMAP Server responds with capabilities and welcome string
- Outlook requests capabilities
- IMAP Server responds with capabilities string
....
....
....

Outlook is supposed to attempt to login at this point, but never does. I
thought maybe something in the capability string was annoying outlook, so
here it is:

* CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT
LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED
I18NLEVEL=1 STARTTLS AUTH=PLAIN AUTH=LOGIN

There is no problem with the connection. I can do all of this from telnet
and thunderbird works perfectly.

Does anyone have any ideas?
