Outlook is not supported by Comcast, my ISP, but Outlook Express is. I have had multiple email accounts all along, and my Comcast accounts work fine, but now my Gmail account is going crazy. I continually receive a ‘Send-Receive Error’ and the message: “Task Synchronizing Subscribed Folders” for my Gmail account reported error (0×80040813). Also a message from Outlook: “Failed to Update Headers” appears. Finally, some of my Gmail messages are not coming to my Outlook, (I know this because they come to my iPhone) Help!
