Migrating from old hardware to new hardware. Single Exchange 2010 server, single site, single organization, single domain.
Right now the old exchange 2010 and the new exchange 2010 are both online. All mailboxes and public folders have been moved over to the new exchange 2010.
I have a couple of users who still use pop mail and I can't get pop mail to work on the new exchange 2010. I checked all the settings, made sure the service is on, tested it from inside the firewall.
When I the Test button in the mail profile setup on a workstation, configuring pop mail:
Connecting to the old server I get:
Log onto incoming mail server (POP3) Completed
Connecting to the new server I get:
Your e-mail server rejected your user name... -ERR Command is not valid in this state.
Everything appears to be exactly the same on the 2 servers and on the ADD ACCOUNT screen on the workstation the only thing I change is the servername.
With the old server, it tests ok.
With the new server I get that error.
Any help would be greatly appreciated.
