Random emails will be missing from trash folder. Some I deleted hours or days ago will be there, while ones from 5 minutes ago might not be. So then when I go searching through everything I can find some emails from years ago and meanwhile others are gone.
Why is this? In gmail I can find all emails with a search even from 10 years ago.
Sometimes I can find them later somehow, and while they will not appear in search they are still hidden somewhere and accessible. They are all clearly still on the server also.
