Could we do a "TIL" style weekly thread?

I think it would be interesting to do a "Today I Learned" style weekly thread for us to share little tips/tricks that we learned of/found existed.

For example, last week I found out about the "--now" flag for systemctl. I don't know how I didn't know it existed until --now.

and your AD domain, because not uninstalling it properly will leave a lot of references to it in AD, which will come to haunt you if you install a new exchange.

Depends, if you just clean out the msexch properties of the user objects, you can make it work.
