Windows – Batch create subfolders in path with spaces

I'm trying to create a subfolder 2015 in many project folders on a shared drive. A previous post here already explained perfectly how to do this using CMD: here. This solution said:

FOR /d %A IN (e:\donuts\*) DO mkdir %A\big

My problem is that the path to the project folders in which the 2015 subfolder will be created contains spaces. So my code looks like this

FOR /d %A IN (e:\corporate folder\*) DO mkdir %A\2015

Where the project folders project1, project2, projectn are found in place of the *. When I run this, CMD interprets this as:

mkdir e:\corporate\2015 

resulting in a folder:

e:/corporate/2015

When I create a dummy folder on the same drive and run:

FOR /d %A IN (e:\corporate_folder\projects\*) DO mkdir %A\2015

a 2015 folder is created in each subfolder, as it should be. From this I conclude that space in the folder path causes the problem. I'd appreciate any suggestions to force CMD to accept the space as part of the path. Thanks!
