Outlook Receive error
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 -

Then you have to recreate the user account in exchange

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
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:

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