You can recover some deleted items, like messages, appointments, contacts, tasks, and notes, even after the Deleted Items folder is emptied or you’ve “hard deleted” an item by pressing Shift+Delete. This feature requires a Microsoft Exchange Server account and doesn’t work with POP3 or Internet Message Access Protocol (IMAP) accounts.
If you’re using Office 365 or another Exchange-based client, you can also restore deleted items using Outlook Web App.
- Click Folder > Recover Deleted Items.
If you don’t see Recover Deleted Items, you’re probably not using an Exchange account or you don’t have a folder selected in that account.
- Click the message you want to recover, and then click Recover Selected Items
.
To select multiple items, press Ctrl as you click each item, and then click Recover Selected Items .
Recovered items are restored to the folder you’re working in.
Your Exchange administrator specifies the retention time for deleted items. After this time elapses, deleted items cannot be restored.
