Norton Anti Spam Addin with Outlook 2010

I've searched and haven't found an answer to this.  I updated this morning to v22.5.0.124 and the tab at the top of my Outlook is gone.  The first time I opened Outlook an error about the plug in flashed but I didn't capture it.  Does it still work even without the tab?  Windows 7 64bit, MS Office 2010 32 bit.
