I use a git-generated static site that has good search, so if people want to find stuff before asking that’s the go-to.

Otherwise, I can search email quite effectively. And oddly, its one of the few things Office Copilot is goos at.

I don’t email is a collaboration tool. It’s an information sharing tool and maybe workflow. Just today I had to email out to like 20 people a data call with a couple paragraphs of instruction. It’s much better than Slack for this. And I can search and find my email and their responses for all of eternity (I’ve got every email going back 20+ years instantly searchable in outlook, good luck finding a slack message from a month ago much less a decade).
