the error code : message corrupted when downloading email from pop3 server

I am using eM Client to receive the email from my company server, it woks fine until yesterday, suddenly the software prompt that “-Err Message corrupted”, and it no longer download the email from the server. I use the tools inbuild eM Client to do diagnosis, the setting of POP3 and SMTP are fine, I still can use SMTP to send the email to others, but cannot download the email. And I tried other software to retrieve the email from the server through POP3 protocol, it is also fine. So please let me know how to solve this problem with eM Client.

What version of eM Client are you using?

If you have a Pro License, maybe open a support ticket directly with eM Client.
