On my Windows Server 2012 R2 Files Server, I created a share named "Ventes" on E:\Ventes.
On my OwnCloud, I configured an external storage with OC Credentials (LDAP MS AD 2012R2). I entered IP of files server (10.33.10.26), share name (Ventes), domain name (micrologic2010) and it's displayed a red square.
The only way that I found to make this working is to create a share directly on drive E and enter an "Remote Subfolder" pointing on folder Ventes. With this way, I can access the folder Ventes and all is working.
I test with my older files server (windows server 2008 R2) and I don't have this problem.
Operating system:Ubuntu 16.04.1 LTS
Web server:Apache 2.4.18
ownCloud version (see ownCloud admin page):9.1.1
Updated from an older ownCloud or fresh install:fresh
