How can I selectively delete emails for instance by subject by sender by date? How can I delete a group of emails pertaining to a specific subject say all emails with subject “motorcycle”?
Please see https://www.xfinity.com/support/articles/search-your-xfinity-connect-inbox. You can search by date by entering a date or range (ex: 3/1/2018 or 3/1/2018-3/12/2018); the words "as date" or "as daterange" will appear. Or type "motorcycle" in the search box and then click the "in subject" option.
After you run the search and verify the results, check the "Select all" box, and then click the Delete icon.
