Help needed! all mails gone after "no doubles"

Is this a good spot to ask for help? I just started using eM a week ago. It was quite a job to get all my mails from Thunderbird imported here. But now something happened… I used the “remove doubles” thing,…and now all my mails is gone, both in my software as on the gmail online…i hope here is a way of getting that back?

Hi, by “remove doubles” do you mean the deduplicator feature?
I’m afraid that if you’re not able to see your emails in your webmail (on your server) either, there’s really no way of getting the mails back.

Do you have a backup, maybe from Thunderbird?

Thank you,
