Hi,
We are in the process of migrating from exchange 2003 to exchange 2010. One of the users who was accessing his mailbox on exchange 2003 via POP is now unable to do it after we moved his mailbox to exchange 2010. he is receiving the below error:

Task - Receiving' reported error (0x800CCC91) : 'Your e-mail server rejected your user name. Verify your user name for this account in Account Settings.  The server responded: -ERR Command is not valid in this state.'

We verified connectivity to the new exchange server via POP and it is working. Also, we have verified the user' credentials and they are correct.

Please advise.
Thanks -

Hello
open Outlook and export everything to a PST file

disconnected the mailbox in Exchange, created a new mailbox, deleted the Outlook profile from the workstation, created a new one and imported the PST

Probably it's corrupted

It is not related to the user account. i have tried with another user and got the same problem. It is an issue in POP3 protocol on the exchange 2010.

Do you an antivirus service for scanning email?

If yes, disable the service and check if the error still occurs

Is POP3 enabled on Exchange 2010 and on the user account?
Any reason the user isn't using Outlook Anywhere? POP3 is an awful protocol.

Do a POP3 telnet test:

Hello,

Can you try resetting the user password once and check if it is working fine.
Also please remove the saved passwords on the computer using below steps before you login and check again.

1) Open User Accounts by clicking the Start button Picture of the Start button, clicking Control Panel, clicking User Accounts and Family Safety (or clicking User Accounts, if you are connected to a network domain), and then clicking User Accounts.

2) In the left pane, click Manage your network passwords.

3) Click the password that you want to remove, and then click Remove.

Thank you guys, the problem was solved by installing exchange 2010 SP3. I think this was a bug in the exchange 2010 version we had (14.0 - build 639.21)

There was a bug in the Exchange Version we were running. Installing Exchange SP3 fixed it
