error pop3 server failed to process your request


I hope someone can help me.
I have the Em-Client (free version).
I hereby call from my Hotmail / Live accounts.
For some time now I keep getting the message
“error pop3 server failed to process your request”
This message appears often, every 15-20 seconds and then not again for days.
Can bring about the Google Search Have nothing in experience which further helps me.
Has anyone here also get this message or can tell me on this?

Sorry for my bad English.
Have it translated for me with Google Translate.

Thank you

Hi, are you able to receive emails despite this issue? What version of eM Client do you use (help - license)?
