On my wife's system, Win 10, this error message keeps coming up:

[POP3] Can't retrieve POP3 message due to the following reason: "-ERR Message 17 expunged."

I've checked all of the settings and the diagnose function shows everything to be OK. Program, and Win 10, are on the latest updates. I am not having this problem on my system using the same ISP. If she opens Live Mail, still installed but not used, her email comes through OK. I also posted this on the emclient forum, but given how great folks are here, I thought I would ask.
