Telnet not working for pop3/exchange2003

I have a user named jimmy dean. Jimmy is setting up his phone for email, and instead of using IMAP4, he wants to use Pop3. Outlook clients outside the office use pop3 including the owner, and no one has had an issue for years. Jimmy tries setting up pop3 on his phone, and keeps getting a username password error. He brings this to my attention and I laugh he obviously forgot his password.

I reset Jimmys password to password, and tested the login with a local terminal, and it worked. He logged into the domain with no problems. He tried accessing mail through pop3 and once again it fails. saying Bad user/password. I tried telneting into the server
telnet mail.domain.com
user jimmy.dean
pass password
-ERR Logon failure: unknown user name or bad password.

I can login to the domain and I can login to OWA with jimmys credentials, only pop3 fails. No one else that uses the exchange server is having an issue. What do I do short of deleting jimmy and re-creating him?

I assume that you have checked AD user properties and that POP3 is enbabled?

Yes.

This account was working with pop3 until today when Jimmy tried setting up his phone.

Check the application log on the exchange server you are telnetting too, it will provide more detail than simply "bad password"

Has this user logged on to Outlook or OWA to initialise his mailbox?

I'd guess guswebb is right, but maybe you can check about going into the mail setup( Control Panel) for the client and choose this connection requires authentication and put in their login info here.

=========================================================
I assume you are referring to the event viewer logs (Application logs). Believe it or not, there is not one instance of this failure present in the logs. I have tried the telneting at least 50 times in one hour, and not a single instance of failure in event viewer (application)

and Yes the user has used and continues to use OWA.
SCarrison

very very odd

Is the server you are telnetting too the server that the mailbox is held on or is it a front-end/CAS box?

Yes
SCarrison

if you log on to the server and go into a command prompt and do

runas /user:<yourdomain>\<affectedusername> cmd <enter>
<enter password>

what happens?  It should start a new command prompt running as the user specified....

what if you log on to the server, go into a command prompt and do

telnet localhost 110
user <domainname>\<username>
pass <password>
stat

??

oops, of course - sorry a bit misleading that one.  and if you do the telnet localhost 110 on the server?

It fails as well, with the same -ERR

Create  a new test user and try to configure the accout in affected user's phone.
If it works, then reset affected user password with less complexity.
============================
Password = password
============================
do you have router ?
Cisco ASA5505
No other users are having issues. thus ruling out the router/security appliance
============================
are you using SSL ?
SSL for OWA only, does not affect pop3
============================
Telnet <ip address> 110
or SSL then Telnet <ip address> 993

I can use my credentials, and 4 other people have tested the telneting via pop3 (110). Their credentials work, where as Jimmy's continue to fail.

Now the only thing that makes sense in what you have said, is to create a test user for Jimmy to configure his phone for. This may break any connection he may or may not have with the server via his phone, thus giving a chance to reset his password again.

 I will test this theory, and let you know ...

I had the user connect to the server with a testuser. And Jimmy was successful in the connection. He still can not connect to his account though, and telnet testing fails on his account as well.

Well whats the easiest way to delete jimmy and recreate Jimmy with same login credentials?

.spt should of course read .pst!

Import the previously exported items to his mailbox.

How do I restore his .pst to the server?
guswebb

Using Outlook-->File-->Import and Export-->Import from another program or file-->Personal Folder FIle (.pst)-->Browse (and point to the .pst file you created when exporting from Outlook)-->Next--> accept default options on next steps and Finish.

how does that save the information in the pst to the server? I ask, because i have restored the pst to the users account by way of the client terminal, however i checked and the pst was restored to client not the server.

It sounds as if you are using a .pst file as the default data store on the Outlook client and that's why the email isn't showing in their Exchange mailbox. Please check Outlook-->Email accounts/Account settings-->Data files. Do you see the Exchange mailbox in the data files lists? Is it selected by default? If not, select it, and then you will be reading the contents of the user's mailbox from Exchange. If you still have the .pst contents visible in Outlook under Personal Folders container (or similar) on the left-hand directory tree, then you can simply drag contents from this store in to the Exchange mailbox folders which should now be displayed at the top of the directory tree in Outlook.

Hope this helps.

I appreciate the experts assistance with this debacle. Unfortunately I was forced to delete/recreate this account. Guswebb, was the closest since I had to delete and recreate. I split the points between the experts, based on the effort put forth. Thank you for your help.
