Windows Live Mail Error: can’t update contact information

Hi,

Trying to add a contact both from an email received and through the add contact function, only to received the following message 'the contact information could not be saved. Check the contact's information and try again'. All contact information is correct.

Previous advice on this forum states to 'sign out' of Windows Live Mail via the icon at the end of the Home ribbon and sign back in again.

Have tried this, was able the add the contact when signed out but once signed in could not view the signed contact nor add the contact, still receiving the same error message.

Any recommendations on how to fix this?

We are using Version 2011 (Build 15.4.3555.0308) on Windows 7

Thanks
