The other day I looked for some information in my sMails. Both my archieved old Folders are empty!

Do you remember roughly the last time they were there? Were there any folders that did not get wiped?

No, sorry, I don't :-(

Inbox and Outbox still hold mails. I couldn't say, if older parts of them may have been wiped as well. While I only archieve and organize mails from the Inbox, since they include basically all outgoing conversation anyhow.

My saved folder is empty as well, so I wonder if they cleared stuff. My most recent sMail is from 2017, so I can't say I've kept up with any changes with it.

- You wouldn't happen to know anything about sMail archive clearing, do you?
