Dear Vaibhav Sapkota
Thank you for contacting us about the Microsoft Community Support Platform!
Understanding that you are currently experiencing issues with Azure DevOps email usage.
Your issue seems to require more specialized support, I suggest you try to seek help in Azure - Microsoft Q&A, where a dedicated Azure board exists, where more experts in related fields can provide you with better solutions. You can raise specific situations and share your ideas for solving the problem on the forum.
Finally, although I cannot assist you further, I hope the information I have provided will help you find a better direction. I will keep this issue on file in case our great volunteers come up with ideas for you.
