Using classic Outlook for Windows in business environments
There is no documented setting in Classic Outlook for Windows to move the flag icon farther away from the delete button or add permanent extra spacing between those message-list actions.
A supported way to submit this product suggestion is:
- In Outlook, go to File > Feedback > Send Feedback.
- Describe that the flag and delete buttons are too close in the inbox and that more spacing would reduce accidental deletions.
Related documented behavior:
- In recent Outlook UI behavior, the flag icon in the message list appears on hover by default.
- There is no built-in setting documented to keep the flag permanently visible in that view.
