Mounting smb shares on OS X accessible with Microsoft account

I have a Windows machine which shares a particular directory and only an owner of this directory is able to access it over the network. Owner account is linked to Microsoft account.

I am trying to mount this share from the terminal in OS X (mounting from Finder works OK), but I am having issues, I believe because the account username contains '@' character.

I tried the following:

mount -t smbfs '//username%40outlook.com:password@hostname/path' local_dir
mount -t smbfs '//username\@outlook.com:password@hostname/path' local_dir
mount -t smbfs '//"username@outlook.com":password@hostname/path' local_dir

First command gives me authentication error (I guess %40 is treated literally), and the other two give me "URL parsing failed". On OS X I can't pass username and password with -o option.

I also tried mounting with -t cifs but with that I get the strange output

mount: exec */path/to/mount_cifs* local_dir: No such file or directory

(note that I can't c/p from OS/X right now so I shorthanded the path to mount_cifs)

Can anyone provide a workaround for this?
