Using New Outlook on Windows for personal email, calendar, and contact management
An easy workaround for this is:
- add an asterisk at the end of the subject for any email that you are composing that you want to flag for follow up.
- Create a category such as "follow up" or "waiting"
- Create a rule that looks for any email with an asterisk in the subject and adds the selected category tag
- Add the category to your favorites in the Folder Pane and you can easily track outgoing emails.
