Emails are very important and sometimes, you may accidentally delete an email which you need. Luckily there are backups available for the emails. You can recover the backups of your emails from the following link:
You would select the email which you have deleted and move it to the main inbox at the top right hand side. The emails are backed up daily. This means that if an email was deleted on the same day, it wouldn’t be possible to recover.
