I have just installed eM Client. All went very smoothly and it seems to be working fine using my existing Gmail account - I can send and receive, view folder contents, etc. Everything seems to be nicely synced, so the emails I see in eM Client match what I see in my Gmail app on my Android phone and via the Gmail web client on my PC, going back a few years.
EXCEPT… All my emails since 4th April this year are not visible in eM Client, even though they are via the other facilities I mentioned. They don’t import from the server when eM Client syncs - this affects both Sent and Received emails. There’s nothing in Junk E-mail either, Archiving is off, and I can’t see them hidden anywhere else. Curious, too, that’s it’s recent emails that aren’t syncing, rather than older ones. It’s not as if I have enormous mail volume either - only a few hundred emails in total, across all folders.
Apart from this, I really like what I’ve seen of eM Client so far. I hope you can give me some pointers to fixing this, as I’m keen to use this.
