No. Yolo. (Also, in the past 20 years I never needed to find any personal email that's older than a week, so I'm not terribly concerned about the effect of dataloss.)
If it's possible to give any detail without giving too much, I'm curious what the nature of the situation was and what the saving document was?
On the flip side, when a company refuses to acknowledge things like arbitration opt-outs that comply with the requirements articulated in the ToS (you know who you are), I email myself a copy of the Exchange trace report showing that the server never recorded a reply. I’m also usually open that I’m doing that, too.
Generally speaking records are an asset not a liability, unless you’re up to something shady. Generally.
I have almost every email of my life, so it's easy to find them.
