Recover deleted emails

[#1]

I have been an absolute numpty and just managed to delete all the emails from my inbox. Given we are just finishing building a  house, there are alot of important messages on there. Is there any way to recover them at all?

Hiya @fjrpilot, thanks a lot for getting in touch and I'm really sorry for the delayed response, we've been super busy lately. 

Before I raise a task with our NetOps Team to see if there are any emails to retain from the latest 7 day snapshot, can I ask whether you've tried t see whether they're still available in the "Deleted" folder on webmail?
