Question

where did the select all button go in outlook,

i want it back

Answer 1

Restore the selection boxes in New Outlook by opening Settings → Message List → Layout, then selecting Checkboxes. This setting has restored the missing checkboxes for users affected by the interface change.^1^

After enabling it:

1. Return to Inbox.
2. Click Select at the top of the message list.
3. Select the checkbox beside Inbox to select every message currently shown.^2^

If Checkboxes is not available in your version, click one message in the list and press Ctrl+A. This selects all email in the active folder.^3^

If neither the setting nor Select appears, use Help → Feedback in New Outlook to report the missing control; this may indicate that a recent interface change has not reached every installation consistently.^2^
