Once a message is deleted there is no way to recover it, to my knowledge. But message retention in Slack is infinite. Further, sessions are infinite, at least last I set it up.

I think we set something like 1 year of retention for "public" channels, 9 months for private, and then certain channels can lower it beyond that. Same for files. And we have our tokens expire once a month.

The defaults for Slack are pretty insane.
