I manage Exchange servers.....

So you would know that it is no picnic but you could:
1. Spin up small VM
2. Restore mailstore until you get about where you need to be data wise
3. start trying to recover emails

This could be done since most Gub agencies require a pretty standard grandfather, father, son retention all a backups for DR purposes. In other words they would have 3 genenerations of backups for daily, weekly, monthly, anual, and DR sets.

Almost. There is no "restore until you get about where you need to be data wise". The mail store is an .ese file (Jet database). It's all one big, monolithic file with no discernible sequencing or mailbox differentiation, so you have to mount the entire store to make any sense of it.
