It is possible to get into a situation where users could be synced with Office 365 but not have access to SharePoint Online or SkyDrive Pro services. When this happens the Office Save As screen (aka Backstage) shows these Office 365 connections to users even though they can not use them.
Also in the contact card a link called "SharePoint" is shown that points to the users MySite that they possibly do not even have.
There are some group policies that control the Backstage area, but they are mostly all or nothing, removing all SharePoint referencing not just the Office 365 ones.
The workaround below should remove the O365 SharePoint on line content from the Office Save As screen and the "SharePoint" link in the contact card.
This is a known issue, it could be addressed in a future version of Microsoft Office.
