Recursive folder search with Exchange Web Services in single call?

My C# application mines email data from exchange via EWS, searches usually take 1-2 minutes. I recently ran into a client where it is taking ~60 minutes to retrieve one user's data.  I am trying to figure out a way to bring that number down, even getting it down to 30 minutes would probably work.  The user in question has a 17GB mailbox with many folders and subfolders (I don't know the exact number).  I suspect the folder tree is more of a problem than the actual mail volume, I'll get to that in a minute.

I currently enumerate all the folders in a user's mailbox and then make a "FindItems" call to each folder using a search filter to retrieve only the last day's worth of data.  I suspect that what's taking a lot of time is just making all those calls for folders which probably don't even have data we need anyway. Is there a way to just make one recursive call to the inbox?  Ultimately the data I end up getting back isn't a lot, I have other users with a lot higher daily volume of mail which I can retrieve quickly, I think because they don't have the complex folder tree which this user has.

It would be nice if you could do a FindItem with a deep traversal, but this says that it isn't supported.  Presumably because of the risk of returning a mountain of data:

But the article does suggest that you can do it by creating a search folder in the mailbox, which seems like a good idea.
