Is it possible to retrieve email if its delted?

[joejons]

Hello,

I'd like to know if it's possible to retrieve an email or if there is any way to prove that it was sent "internally" to a group of people on the same server if it has purposely been deleted? Would it leave a footprint? Of Any sort? Where could I look for this? I'm sorry I'm not a technical person at all so if this is possible I'd need assistance!

Any help would be greatly appreciated

I did not find the right solution from the internet.
