Hi @Ritesh Singh ,
Welcome to our forum!
Where do you access the feedback page? Via File>Feedback in some Office programs?
If so, based on my test, i can submit feedback successfully:
What's the version of your Office 365? (File > Office Account > About Outlook). Please make sure you have upgraded your Office to the latest version.
On the other hand, if you have any suggestion about Office products, it is recommended that you could post the functions you expect and your sincere suggestions on the website dedicated to collecting feedback. We sincerely welcome your suggestions, and thanks for your understanding and support!
