Hi @Dev-Manish ,
Please check in outlook settings if you have Microsoft teams enabled as an online meeting provider (refer below screenshot). Graph Calendar API will fetch result based on
onlinemeetingproviders enabled for the user's calendar.
Also, Please check this post if the user is newly created: https://learn.microsoft.com/en-us/answers/questions/815263/microsoft-teams-url-is-missed-when-creating-a-even.html
Hope this helps.
