Dear Joseph,

This problem occurs because Exchange Server 2007 has its “MaxCommandSize”
setting for POP3 configured to use the value "40" by default. This limits
the maximum size of a single command to 40 bytes. Some users with long UPN
(like testuserwithverylongna…@myemaildomainame.com) may fail to connect due
to this limit.

This article contains steps for you to follow to set up your Post Office
Protocol 3 (POP3) or Internet Message Access Protocol 4 (IMAP4) account so
that you can use a Microsoft Exchange Server 2003 or Exchange Server 2007
account. This article also provides links to other articles that may help
you learn more about and troubleshoot problems with Microsoft Exchange
Server accounts.

Outlook Express and Outlook repeatedly prompt you for your password when you
check messages on an Exchange Server-based computer
