Reclaiming Reassigned Issues

Every work item a rule hands to a coverer is recorded in that rule's reassignment log. When the absence is over, open that log and take the work items back.

Open the reassignment log

Open Apps > Out of Office Assistant in the Jira navigation bar and choose the My Rules tab.
Find the rule that did the reassigning. A rule you paused stays in Current rules with the status Inactive; a rule whose end date has passed sits in Expired rules, or in Past integration rules when an integration created it.
In that row's Reassignments column, select the button counting the handovers, for example 8 of 8 passed. A rule that moved nothing shows - there and has no log to open.

The Reassignment Log dialog opens on its Reassignments tab, listing one row per work item that rule moved.

The Reassignment Log, opened from the Reassignments button of a rule in My Rules.

What the log records

Work Item, Summary and Status - the key, the title, and where the work item stands now. The key is a link into the work item.
Last edited - when the work item last changed, so you can see what moved on while you were away.
Reporter and Assignee - who raised the work item, and who holds it now. The assignee is the coverer the rule picked.
Trigger - what moved it: the rule reassigning as it ran, or a Bulk assign you ran yourself.

The second tab, Failures, lists the reassignments that did not go through and why. Approver swaps are recorded alongside assignee reassignments, so a swap that failed because the approver coverer is out of office too is listed here.

Take the work items back

In the Reassignment Log, tick the work items you want back. The header row's checkbox selects every row.
Under Take back work items assigned in your absence, select the reclaim button. It carries the count you ticked, for example Reclaim 3 Work Items, and stays disabled while nothing is selected.
Select Close to leave the dialog.

Each reclaimed work item goes back to the person the rule took it from. Anything you leave unticked stays with the coverer.

The dialog states the condition: "These work items were assigned to coverers during your active Out of Office rule. Once the rule expires or is paused, you can take them back." To take work back before the rule's end date, pause the rule first.

Approvals return on their own

When a rule that names an approver coverer ends, the work items whose approval was passed to that coverer are returned to the original approver automatically.

How long you can reclaim

The log lives on the rule, so the reclaim window is the rule's own retention window.

Up to 30 days after it ends - the rule stays in the list whether or not it reassigned anything.
Between 30 and 180 days - only rules that actually reassigned work items are kept, which is what keeps those work items reclaimable. A rule that reassigned nothing is removed, whether you created it or an integration did.
After 180 days - everything is deleted. The reassignment log goes with the rule, and its reassignments can no longer be reclaimed from the app.
