If you have accidentally deleted items or folders from your mailbox, you can recover them from your Deleted Items folder. If you have emptied your Deleted Items folder, however, follow these steps to restore deleted items:
- On the Folder tab, in the Clean Up group, click Recover Deleted Items.
- On Recover Deleted Items menu, select the items you want to restore (or click Select All), select Restore Selected Items, and then click OK. Outlook will transfer your recovered items to your Deleted Items folder, and then you can move them to a more suitable storage location such as folders, tasks, appointments, etc.
NOTE: You can recover a deleted folder and its contents from your Deleted Items folder. If you empty your Deleted Items folder, your folders will be permanently deleted, but you can retrieve the contents of deleted folders from Recover Deleted Items.
