It frees you from time-consuming operations. In the Outlook Options dialog, click Mail in the left bar, and then click the Spelling and AutoCorrect button in the Compose messages section. This is COOL!!! Full feature 60-day free trial, no credit card and will not auto-charged.
If the Outlook one is as good as the Excel kit, you should have no problems at all. I have used KUtools for Excel and have had no issues with it what so ever.
