Bingbot crawling emails in O365

Copper Contributor

We were doing a phishing test across our organization and saw several "clicks" from IPs related to Bingbot crawler. I always thought Microsoft Search within O365 is separate from Bing Search, so there should be no reason why Bingbot should crawl emails. Does anyone know if the Bingbot crawls emails in Office 365?

There is a "Microsoft search in Bing" feature:
I have seen that. But this feature has been around for a while. The Bingbot IPs have recently started showing up. Also, Microsoft Search in Bing doesn't return emails in the search results which makes me believe that emails are not crawled.
