Skype contact

I have a skype account, and msn account. I've merged them ever since the announcement of msn messenger being eliminated.

all my contacts has work well except for one.

i've been using outlook.com since early this year.

Now that Microsoft is bringing Skype into outlook.com.

All my contact in facebook, msn messenger and skype are appearing on my messaging list and people list.

And all except for one show absolutely correct status (when they are online on skype, outlook.com display the same)

Only for this contact, she is online but outlook.com will forever show she is offline.

I contacted skype, and have done the recommended unmerge and Re-merge account - ISSUE UNSOLVED

I've tried refreshing my page as suggested on HELP on outlook.com - ISSUE remains.

i've tried on different machine - issue remains

I've tried deleteing each other on skype and re-add each other - issue remians

I just wonder why??
