Facebook and Linkedin contacts in Outlook

[So]

I've been having problems with my iPhone losing contacts.

Whilst trying to find them I note that in my Outlook desktop app I've now got Facebook and Linkedin contact folders. Which cannot be deleted. Some of the missing contacts were in the Facebook folder.

How did I get these things? I don't really use FB or Linkedin.

Many thanks.

Maybe it's the Outlook Social Connector:

Looks likely.

I cannot remove it. It says you've got to be an administrator, but once I log on as one it still says you've got to be an administrator.

Those contact files are quite new. Did they arrive as part of a Windows Update or something?

I'm not sure. The 'Outlook Social Connector 2106' is in the Inactive Add-Ins section for me so it looks like it's been around for some time.
