Using New Outlook on Windows for personal email, calendar, and contact management
Thank you for letting me know.
Your Inbox is currently sorted by "Subject": shown by the ^ beside the Subject heading. The line with the > arrow is the subject-group heading that Outlook adds when messages are sorted this way.
Change the sorting back to "Date":
- At the top of the message list, click Sorted by icon.
- Under "Sorted by", select "Date".
See screenshot below:
I really hope this information is helpful! Let me know if you have any further questions or concerns.
Thanks!
