I moved to IMAP for my Outlook 2016 email service under Windows 10. I keep my email quantity small with frequent archives, but I canít figure out why when there are, say, 50 emails on the Comcast server, yet my iphone displays 160. I deleted all of the emails and still 160 reload. If there are only 50 on the server, where is my phone finding the old emails? Is this an Outlook or Comcast issue.
