Hello. I am trying to setup a POP3 account to a client that has Outlook 2010 and connects to Exchange 2013 CU2. I started POP3 services to Exchange server. The client already has an Exchange account. I set up a second POP3 account. Outlook test is ok. But when the user tries to send an email using the pop3 account, the email message returns with "invalid message content".
How can I solve this?
Regards
