After moved mailbox from Exchange 2010 to 2013 database some clients get this error which use POP3 account;
"Task user@domain.com - receiving reported error (0x800CC90) : Your incoming (POP3) e-mail server has reported an internal error"
They can send and receive email successfully but after send-receive process the error appear.
-The error just on same departman clients, others can work smoothly.
- Client can access to exchange server on required ports.
- No mistake on outlook configuration.
- there is no firewall or antivirus software on clients.
I need help about it.
