I need to recover deleted mails.

I need to recover deleted mails.

Hi,

My iphone has been doing some really weird stuff for the last couple of days. It deleted several emails from my account, which i have been unable to find either on the Archive or the Trash bin. I was wondering if it is possible to recover these emails since most of them are work related and quite important. I have already logged out from the Mail native app, to avoid any further email mishandling.

Kind regards.
