I have an outlook.com account that is my main microsoft account, and am running the following devices:

Dell inspiron, Windows 8.1 preview, auto updating

Acer w510 tablet, Windows 8.1 preview, auto updating

Nokia lumia 920, Windows Phone 8, auto updating

My email seems to be syncing ok on all devices, although a bit glitchy due to the issues of last week...but all seems well.

My calendar seems to be syncing well.  I have my outlook.com calendar as my main calendar on Outlook 2013, and changes I make on any device appear to be syncing in a timely manner.

My contacts, however, are not syncing at all to any of my devices.  The list when I am on Outlook.com on my computer is completely different than what I see in my People app on that same computer, and changes made on any device are not getting back to outlook.com.  This is very frustrating.  I have tried every potential solution I have seen here and elsewhere, and nothing has worked.  

Please let me know if you require any further information in order to help me solve this issue. 

Thank you to anyone who can help me with this! :)
