Using OS X El Capitan with MSoft Office 2011, Outlook 14.5.6.  Problem started with going to Tasks Folder and no tasks are shown.  However, Reminder still popped up the tasks even though the Tasks Folder was "empty".  

Have gone through several troubleshooting steps including:

• Reindex Spotlight
• Insuring Spotlight was turned on
• Rebuild Identity
• Take backup identity from Time Machine
  • was able to find one that had the tasks and exported them to .olm and imported back into current Main Identity to no avail
• Ran Disk Utility with no issues

Now I have rebuilt my drive with an earlier version of Time Machine and am back to my original problem where there are no tasks showing and the categories are just a portion of the original categories.  All are checked and I am seeing a few emails that appear with one having a category and the rest do not.  Here is Smart Folder info:

• Due Today - No Results
• High Priority - 2 emails show but are not tasks and have no category but only shows if showing "Completed" in filter.  I believe emails marked for followup
• Overdue - 1 email that was flagged for followup

Talking with Apple I have had a lot of support but with MSoft they turned me back to Apple after trying some things.  I have been looking all over for answers and the ones most prominent are to reindex Spotlight, rebuild the Main Identity or use a Main Identity from Time Machine.  Not sure where to go now so looking for some help besides just reinstall.

Thanks in advance for any help!
