Issues with Outlook.com and Facebook chat status

Hello all,

I am hoping someone can point me in the right direction with this, I seem to be having some problems with my chat status updating when using my connected Facebook account.

Lets start with Facebook and Outlook.com chat set to 'offline'/'invisible'.  If I then set my chat status in Outlook.com to to 'available' (with Facebook chat on) this works fine, the status in both Outlook.com and Facebook is set to 'available'  However if I then set the status of 'Facebook chat' to 'off' or my 'availability' to 'invisible' via Outlook.com this status is not reflected in the Facebook chat at Facebook.com, even though it sets correctly on Outlook.com.

Surely if I set my Facebook 'availability' to offline at Outlook.com this status should also be reflected at Facebook.com?

Any pointers?

Thanks,
Regards
