Offline Folder Associations

So I enabled a network share to be availabel offline. Every file in the
folder failed to replicate (the replication process said xxx errors) yet in
syncentre there were no reported errors. Each file appears available offline,
yet when you open it you get a failure.

Ok so 10 years after I first got excited about this functionality working it
still doesn't, I go tot turn it off- there are errors with thirty odd files
when I do this so now I can't even disable offline folders. This is
especially freaking annoying because sync centre cant' tell when I return to
the wired network and the folder is back available again. Because of this
even though I'm now back on the network the failed offline folder association
is keeping the network share locked in offline mode rather than re-polling
the working network share.

So I want to fully delete this old relationship and I can't. How do you do it?
