Fix the issue- Missing Option of Connect to Outlook in SharePoint 2010 Team Calendar

Every time when I go to our Project Dashboard, the following JavaScript error appears in IE8.

When I click Team Calendar and try to sync SharePoint 2010 Team Calendar with MS Outlook 2010, the option of “Connect to Outlook” is missing.  It was working fine.  After talking to 2 team members, one has the same issue too, but the other one doesn't.

 After looking into this issue, I learn something as follows:

·         Running sfc /scannow is not useful at all.

·         I use Office 2010, so running Office Diagnostics is not useful because it is for Office 2007 only.

·         There is no owssupp.dll in Office 14 folder (C:\Program Files\Microsoft Office\Office14). We don’t need to register it in the machine.

·         SharePoint Stssync Handler is required to appear in Manage Add-ons. It is missing in my IE. [Main Reason]

How to fix this issue?  It is pretty easy.

Go to Programs and Features-> Right Click Microsoft Office 2010-> Change->  Choose Repair.  

After that, the following issues are fixed.

JavaScript error goes away in Project Dashboard.

The option of “Connect to Outlook” appears in SharePoint 2010.
