imap unable to upload message parse error

I just installed eM Client on new Windows 10 computer.

Imported email and contacts from Windows 7 Window Live Mail.

I see emails and contacts. Have performed test send and receive.

Getting Error: [IMAP] Unable to upload message “to folder” “Junk” (parse error, date out of range.)

Same error for “Inbox” folder.

Any ideas on how to resolve?
