It seems possible the email hacking could have been discussed at the infamous Trump Tower meeting. There doesn't seem to be any evidence that hacked emails were discussed but it's not like they were recording meeting minutes. None of the participants have been very forthcoming and they all have reasons to be less than candid. This is the timeline the Washington Post reported on last August.

It’s important to note the timeline here. This meeting was on June 9, 2016 — less than a week before The Washington Post first reported that hackers thought to be linked to the Russian government had hacked into the DNC and stolen communications, including emails. An indictment obtained by special counsel Robert S. Mueller III indicates that the intrusion began in mid-April, shortly before a Trump campaign adviser named George Papadopoulos is told by a Kremlin-linked professor that the Russians had “dirt” on Clinton. The day before the Trump Tower meeting, the Russians set up a website called “DCLeaks,” which was used later that month to begin publishing documents stolen from the DNC. Link
