find the mailbox which a message is in

Hi

I use several levels of subfolders in mac mail, eg I might have one called Business > Clients > France > Aquitaine > Example Co > Orders > July 2015

Imagine that I do a search and amongst the results is a message which is in that folder. I can see the message by clicking on it and I can see the name of its immediately enclosing folder (July 2015).

But I can't see where the mailbox July 2015 is, ie there is no way of finding the crumbtrail Business > Clients > France > Aquitaine > Example Co > Orders > July 2015.

In an earlier OS X this used to be possible, but not in Mavericks, Yosemite or El Capitan.

Does anyone have a solution?

Cheers

Charlie
