Recovering deleted items from your @northwestern.edu (Office 365) account using Outlook 2016/2013 for Windows
When you delete an item (e.g., message, folder, appointment, or contact), Outlook moves it to the Deleted Items folder. If you need to retrieve an item, you can easily it from that folder and move it to another folder.
When you empty the Deleted Items folder, its contents are then transferred to a hidden folder. You may be able to recover items from that folder, provided you haven't emptied it. Note that if you've purged items from Recover Deleted Items, they are not recoverable at all.
- From your list of folders, click Deleted Items.
- Click the Folder tab, then click Recover Deleted Items.
- The window displayed contains items you've deleted within the last 28 days. Highlight the items you want to recover; press Ctrl while selecting items to select multiple items at once. Note that all items in the recovery window appear with an envelope icon, regardless of object type. If the item recovered is a non-mail item (e.g., a contact or appointment), Outlook will recover it properly with the appropriate icon when it appears back in your Deleted Items folder.
- Make sure Restore Selected Items is selected, then click OK. Note that this will place the items into your Deleted Items folder. From there you can move or drag them back to your Inbox or any other folder.
