I recenctly started using Office 365 Outlook. I copied my old emails through IMAP to Office 365 with Pegasus Mail 4.52. If I check the emails in Pegasus by IMAP everything is correct, but when I look at the folder through the web app the email dates are set to the date they were copied to Outlook 365. If I open the email in web app (view original message), the date is correct.
How do I set Outlook web app to use the actual date present in the email headers as the message date?
