Hi, same issue here (duplicate post Owncloud 9.1.1 and folder permissions Windows server 2008R2 issue (Junction links not working) - #2 by anon30676603) did anyone find solution?
On my side, from web interface of ownCloud, it says “Storage not available”. I’m 100% sure of the user I gave permissions to access files. Does ownCloud read permissions from folders which are junction links (i.e pointing to another folder?)
