If you don't see the deleted messages that you wanted, it means they are permanently lost. This will attempt to recover as many messages as possible and put them in your Deleted folder. At the bottom of the window, click recover deleted messages.

When using the web-based version of Outlook, if you need to recover an email that might have been accidentally deleted from your inbox, you can go to the left pane of the window, click the Deleted folder. When recovered, these messages go back into the Inbox. When found, select it, and then click Recover. The search function can be used to locate the message. If the message is not in the Deleted Items folder then right-click Deleted Items, and then click Recover deleted items. To recover it (along with all the messages it contains), right-click the deleted folder, click Move, and then choose a folder to move it to. Deleted folders will appear in Deleted Items as a sub-folder.
