Is it possible to recover items recently emptied from my Deleted Items Folder?

Yes - with the new version of OWA, it's much easier to view and recover these files.

1. In the Navigation Pane , click Options .
2. Scroll down to Recover Deleted Items (at the very bottom) and click View Items .
3. A list of deleted messages from the past several days will appear. Make your selection (use the Shift key to select more than one) and click the Recover button above the list, or click Permanently Delete to clear these files from your account completely. If the file isn't there, the recovery time has probably already passed.
4. The file will be sent back to your Deleted Items folder - not your Inbox.
