I have an unnested subfolder in Gmail that will NOT sync in eM Client. Renaming the folder has no effect, nesting/unnesting has no effect. Ran eM Client as admin (just in case) had no effect. This folder has less emails than other subfolders, and all other subfolders (nested and unnested)/contact/calender events sync fine. I am getting no errors while syncing with Gmail.
IN eM Client, right-click on the All Mail folder and choose Properties > Repair. See if that makes any difference.
As far as I can tell that seemed to fix the problem. It’s still downloading messages, but I’m seeing stuff that was definitely not there before. Thank you!
