My OS is win 10 pro 64 bit and I have Office 365 and use Outlook the OWA version. &nbsp;I have tons of email in my Inbox, and tried to delete by searching for like &quot;Zoosk&quot;. &nbsp;Although the result displays lots of messages, but when I select the top folder and select, it only seems to highlight only about 7 messages. &nbsp;It must be a setting some where. &nbsp;How do I change this to select All when I check that box on the top of the search results. <br />
