I have three inside salespersons. One, who has been creating quotes and emailing PDFs for a long time, now is finding that his email did not go to the customer, nor is the email with attachment showing in the Activity timeline. The same is happening to me--System Administrator. And now one other from the sales team is having the same. But two others are not having this problem--quotes going and emails with attachments recorded

I posted once but didn't receive any response.  Has someone developed a button we can place on the quote object that would allow you to "delete" multiple line items all at once?
