Contacts not sycning from Outlook.com to Andriod Sony Xperia L

I have been using Outlook.com for my email, contacts and calender to ensure everything is keep organised; however I have noticed that althought both my email and calender sync without issue to my phones the contacts don't.

When setting up the account , everything including all my contacts download without issue but thats the end of sync for contact; I can make changes either on the phone or computer and these don't sync to or from the phone.

I have tired removing the account, and reinstalling and I have checked the server details and everything seems right; like I say, email and callender work without and problem.

The phone did recieve a software update, upgrading the operating software; I am pretty sure that that the contact sync was working before so I am unsure if this is and Microsoft issue or Sony one.

Device is a Sony Xperia L running Jelly Bean 4.1.2 (recently aweek ago)

I don't use the Outlook app, I use the standard email, contacts and calender which comes with the phone.

Any help would be gratefull received.
