Can you force a re-upload of an IMAP folder to the server?

I’m using the eM Client to manually move all my email from one IMAP provider to Gmail.

As I move each folder, sometimes the emails don’t all copy up to my Gmail account, sometime they do.

Can I manually force a re-upload from the eM Client to my Gmail account?

I’ve been looking for this option, but all I can find is the reverse which allows me to delete the local folder and re-download.

Hi Sam, unfortunately there’s no option to force upload your messages onto the server, all you should have to do to upload the data on the server is to move the emails onto the IMAP folder and wait until the synchronization is finished.
Is it possible some of the message exceeds a maximum size limit for upload to the server?

Thank you,
