Hi @Wendy Johnson ,
Why not? Why is this function missing from the new version when it was clearly available in the older version.
As far as I know, the new Outlook for Windows is still being improved over time, so at this point of time, you may notice that some old features haven't yet been implemented into the new version.
Regarding your concern of the Resend function, as mentioned earlier, I've tried submitting the suggestion via the Feedback portal. And I've also tried contacting the in-app support from within the New Outlook. According to the reply there, this has already been considered for a future release.

For now, if you really need to use this feature at present, as aforementioned, I'd recommend switching back to the classic version of Outlook using the toggle.
Thanks for your understanding and hopefully we can see this feature available in the new version soon.
