How can I dis-able the auto-complete feature when using Outlook
thank you for your feedback. You can turn this feature off under settings>Mail>Compose and Reply>Text Predictions
Psst... Just put a 'z' right after your cursor B4 you actually start typing-that pretty much kills auto-complete's "helpfulness."
Compared to the major annoyance of constant text suggestions jumping in your face while writing, having to push a little 'z' along while you type is minor in comparison for peace of mind. Hope it helps!
