Like a number of other people, eM Client stopped working in the past two days for my POP account. I have now switched over to IMAP and have functionality back. Is there a way to merge the emails from the POP account in to the IMAP account (same address)?
Yes, before you delete the POP3 account from eM Client, you can move the messages to the IMAP folders. Either drag-and-drop or select the messages and right-click > Move to folder.
