Hi Juan Pablo,
This is what I’ve found concerning using Azure shares with Owncloud, and in general about using from Samba in Linux:
It think the problem is a matter of versions, Azure shares are compatible with Samba packages version 4.5.8, distributed in Debian GNU/Linux version 9 (Stretch), but not lower versions as the one distributed in Debian GNU/Linu 8 (Jessie), in this case 4.2.14 version.
I give you 2 links I’ve just wrote about that question:

I hope it helps!
