Disappearing Folders

eM Client appears to have deleted and/or removed every email I have stored prior to April 18th. I hadseveral archive files that have gone from the folders list.
Where might I find them?

Hello,
where did you have those folders saved - in Local folders, or on the server?

Same problem here: I have moved many mails to various folders (the folders are also visible in GMail), but after syncing the mails disappear from emClient (and are not visible in GMail too).
I’ve checked: I have no archiving active in eM nor in GMail. Unfortunately also backup is not active in eM… Any ideas?
