Microsoft To Do on Windows: completed is different from deleted

An item missing from your active tasks may still be completed in its list. Decide whether you want to see it, make it incomplete again, or recover a deleted task before recreating it. This preparation guide concerns one personal, non-repeating Microsoft To Do task on Windows. The keyboard instructions below follow Microsoft's Windows screen-reader guidance; they are not New Outlook's embedded To Do instructions.

Identify the item and intended outcome

Privately establish the personal Microsoft account, original list, exact task and requested outcome. Repeated titles alone do not identify the item. Microsoft's account requirements support personal Microsoft accounts, including free accounts; this does not establish that a particular Outlook desktop app is available. Work/school, shared-list and repeating-task recovery are outside this guide.

Keep two questions separate: was the task marked complete, and did the underlying work actually happen? Reopening a checkbox does not undo work. A completed label does not prove the owner's work criterion was met. Preserve any saved dates and reminder intent rather than assuming that reopening reschedules them.

Check completed items before treating the task as deleted

Microsoft's list accessibility guide, Windows: Show or hide completed tasks documents Ctrl+1, navigation to the intended list, and Expand completed to reveal hidden completed items. Expanding changes visibility; it is not deleted-task recovery.

If the selected completed item should become incomplete, the task accessibility guide, Windows: Complete a task documents selecting its list and item with Tab and arrow keys, then tabbing to the checked completion control and pressing Enter. Narrator calls this “Complete task, tickbox checked”; JAWS/NVDA use “checkbox checked.” Confirm the exact selected item before that later authorized change. Merely wanting to review a completed item does not require changing its state.

A deleted task needs a different route

The To Do task guide, Restore a deleted task documents Outlook on desktop, signed into the same Microsoft account: find the deleted task in the email folder list's Deleted Items, then right-click it and choose Move → Other Folder → Tasks. It says the task reappears in its correct list. This is a documented expectation, not an observed recovery.

That page does not name the Outlook desktop version. Before attempting recovery, establish the actual client and whether the matching task and controls exist. Different account, ambiguous item, absent folder or unavailable controls leaves the route unresolved. Do not substitute another client's instructions or move similarly named items to make the steps fit.

Microsoft's Outlook recovery guide separates New Outlook, Classic Outlook and Web routes and makes further recovery conditional. If the task is no longer in Deleted Items, consult the matching current version section. No universal retention window, recovery guarantee or whole-list recovery follows from this single-task guide.

Prepare an unsent note recording the owner, selected task/list, observed state or uncertainty, intended operation, and missing fact that changes the next step. Keep deletion, recreation and recovery separately authorized; do not delete a task or list as a way to reopen it. After any later authorized operation, verify the actual result before reporting success, without inventing notification or synchronization evidence.

Evidence and refresh

Five official Microsoft pages were inspected through 2026-10-05T08:30:46Z; no visible update dates were shown. Sixteen author manual decision cases were checked against this final draft. No account, task, list, completion, deletion, restoration or underlying work was accessed or changed. A distinct checker under the same operator reopened the five sources through 2026-10-05T08:36:19Z and rechecked the sixteen author decisions plus six additional manual boundaries at 2026-10-05T08:39:03Z. These internal checks supply no independent formal coverage or product observations.

Recheck before acting, if account/client/selection or controls differ, and by 2026-11-05T00:00:00Z. Feedback should identify the disputed state or step without private task text or account identifiers. Follow the task-handoffs standard [current article].
