My e-mails are getting deleted from my main IMAP account. I lost all of my e-mails from November. I did not auto-archive, I'm using Microsoft Outlook.
I have it set to a 2000 inbox max. I only have 400+ emails in my inbox right now. And about 700+ in my sent folder.
I also have it set to give me a message when my inbox is full. Also it should be redirecting all of my overflow into another folder I set up. None of that happened.
