one might try FIZBAN11's fix (below) which may seem 'less destructive', to some, and,
I might add, the first time I had seen this particular idea (regarding OUTLOOK, as the culprit) followed up on.
I had success with this on my WIndows 8 machine with Office Pro 2010
{briefly}
Control panel > Programs and Features
choose your MS OFFICE 20?? installation
select "CHANGE" at top
select Add or Remove Features
expand Outlook by clicking the + sign
expand Outlook Add-Ins by clicking the plus sign
select SharePoint Server Colleague Recommendations Add-In
for myself, i just disabled (red X) ALL OUTLOOK add-ins
