Recover emails sent with Windows Live Mail

Good morning.
I signed up for the free trial of Avast Cleanup Premium.
Yesterday, I followed some instructions to clean the hard disk.
Once finished, I realized that it had completely deactivated Windows Live Mail and deleted the emails.
Reinstalling, only the received emails reappeared (moreover from the last few years, so all of them), but the sent emails disappeared.
Do I have any chance of recovering them? How?
Thanks.
