The shortcut (shift + F3) to change the case in new outlook not working

Hi Donald MacDonald2 ,

Good day.

Thank you for posting to the Microsoft Community. We are glad to assist.

After thorough research and consultations, it has been concluded that the feature you are inquiring about is not yet available in the new Outlook. However, thank you so much for bringing this to our attention, your suggestion is constructive, and I believe it could make the use of Outlook even better. We will surely raise your concerns with our Product Development Team and hopefully, this can be included in future updates. Please note new Outlook is still in active development, right now fourteen features are in development and seven more have started to be rolled out. To check for upcoming features, you can check Microsoft 365 Roadmap | Microsoft 365.

In the meantime, we sincerely recommend you post your concern as an idea to our Outlook in-app feedback site Contact support and provide feedback within the new Outlook for Windows - Microsoft Support

Our Product Development Team is committed to enhancing the customer experience by continually examining suggestions to include in the design

and development of future product upgrades based on your suggestions. Hopefully, your suggestion will help many users in the future

I hope this helps let me know if this is contrary to what you need, I would still be helpful to answer more of your questions .

Best Regards

Also autocorrect doesn't work - For example I have set up "wb" as a shorthand for typing "will be". This works fine in Word, Excel and old Outlook, but not in the new Outlook
