Hi Priyanka,
Thank you for contacting the Microsoft Community.
I'm sorry to hear that you were not able to log in to the Microsoft Virtual Day event you have registered. Allow me to provide you with the information.
We appreciate the steps you have taken to resolve the issue. Since the event has already passed, I would suggest re-registering and use a different email address preferably personal email to avoid any restrictions.
I hope this information helps.
