Outbox
If you action a task while your device is offline, the task moves to the Outbox and you are notified that the app cannot connect to the K2 server. You are also notified when last the Outbox was last synced. You can leave the item in the Outbox and, when you reconnect, the Outbox synchronizes with the server and the task completes.
You can instead discard the task item. When you discard a task item from the Outbox while offline, the task item is returned to Inbox. You can undo the discarded task item using the Undo option. The app automatically synchronizes as soon you are back online.
When the Outbox synchronizes but another participant has already actioned an item you actioned while offline, you are notified that the item has already been actioned and you can discard it and refresh your Inbox.
