What's the easiest way to find all the mailboxes, dist lists, aliases, etc. a user has access to?

I'm aware of some inelegant Powershell trickery to get this information but is there some way in Exchange Admin Center to see this? I would think if you're looking at a user in Exchange Admin Center it would show you right there all the mailboxes and distribution lists the user is a member of. Surely such a benign task doesn't require a Powershell script.
