Hi
I am an Independent Advisor, trying to help other users in the Community with my experience in Microsoft products. Please note that I am a user like you and don't work directly for Microsoft.
I am sorry to hear that you are experiencing this issue and I hope the following suggestion will work in your case.
The New Outlook is still in development by Microsoft and new features will be added over the next couple of months.
You can find all the expected dates in this link:

Should the issue you experience have an impact on you, I suggest you revert to the Classic Outlook for now.
Please let me know if that helped.
Regards
Casper
