Sort Outlook Tasks By Subject

Outlook 2007+ cannot sort by task subject field

Outlook 2003 can do this but for some reason it was changed in 2007 (2010?)
When you try this you get the error “You cannot sort by this field”

To resolve if you need to remove Task Subject from the view and replace it with Subject.

1.  Right click on the column heading
2. Select customise current view
3. Click on fields
4. Add subject, remove task subject
5. Now it you will be able to sort by the subject field
