Hi Aalap Verma,
I had the similar requirement to create the invites and sent to the meeting participants. I used the ICS (.ics) file concept to achieve it in outlook. ICS file is text file with all the required details of the meeting. Outlook application can understands the .ics file and opens it in outlook meeting window. I had created custom vbo with code stage in C# to create the .ics text file. Please find the link below to check the C# code.
How to create .ics file using c#?But this requires details of meeting participants (attendees/ Organizer) and meeting start time and end time and time of the meeting. If you need to find the availability of meeting participants and book the meeting, then you may have to use the Microsoft Graph api.
