Contacts not syncing from phone to outlook.com

I can sync contacts from outlook.com using its android app to my phone but cannot sync any contact them from phone to outlook.com.

It is indeed a serious problem for my remote data management, so that if I create a new ctc on the phone while on the road it would not sync at all.  

My Galaxy Note 2 runs its contacts on std android app. Sync my e-mail only by K9 and E-mail client used at my office is Outlook 2010, 32 bits.

I have no more 365 or Exchange either.

Calendar works fine syncing events both ways. 

so I would appreciate you to address it asap, as my working routine is mostly away from desk.

Tks in advance !
