on the surface, no. slashes all go the same way. (and you have space before documents and a space before Programdata)
I'm not sure why yours isn't working. From your command you are saying when I look in documents\fax I want to see into the Programdata folder. (left out all the detail folders). You tested and Windows fax is looking only as far as your documents, fax folder, right. You put a tif file into the inbox on documents\fax\inbox and you can see that document in windows fax.
I'm not sure if you shouldn't create two lower levels links, one for inbox and one for sentitems. I have not done this "fax fix"
Now the safety speech. Create a restore point and consider making and understanding a Macrium Reflect image including its boot cd. When things go horribly wrong we need to have plan b and maybe even a plan c. Also back up contents of folders involved so if Window helps and deletes contents you can replace.
Good luck. Not throwing you to wolves, just haven't experimented.
