Undo "Clear Offline Items" in Outlook

Some tips to share or to avoid from accidentally delete all your emails in your inbox MS Outlook. When I’m cleaning up and organizing my emails in MS outlook, I accidentally click the “Clear Offline Items” in the inbox properties page causes all my important emails are gone.

However, it can be recovered if you are using a Microsoft Exchange Server e-mail account in Cached Exchange mode which I believe most companies setup their outlook in this way.

So what I do is to click “Send and Receive” button to synchronize all the emails in the server back to my Outlook. This is how you can undo the "Clear Offline Items" in Outlook in case one day you accidentally click the "Clear Offiline Itemes" in MS Outlook.
