this has happened to me several times for several days each time. eM Client refuses to sign in to the server (saying the server doesn’t recognize the sign in details) - despite my email address and password being correct. The server is working because I can get in on webmail for that ISP with the same sign-in details. After several days the problem seems to clear of its own accord. I am wondering if I uninstall eM Client and reinstall will it preserve all my stored emails (there are a lot). I have made a backup using em Client’s back up but there is no obvious restore and I have no idea where the backup lives on my PC.
