Hi @Tamizhselvan S

To get attendees free meeting slots you need to use header Prefer: outlook.timezone="India Standard Time". Please find the below sample screenshot along with the body.

{  
    "attendees": [  
        {  
            "type": "required",  
            "emailAddress": {  
                "name": "Diego Siciliani",  
                "address": DiegoS@M****.OnMicrosoft.com  
            }  
        }  
    ],  
    "locationConstraint": {  
        "isRequired": false,  
        "suggestLocation": false,  
        "locations": [  
            {  
                "resolveAvailability": false,  
                "displayName": "Conf room Hood"  
            }  
        ]  
    },  
    "timeConstraint": {  
        "activityDomain": "work",  
        "timeSlots": [  
            {  
                "start": {  
                    "dateTime": "2022-11-16T09:00:00",  
                    "timeZone": "Pacific Standard Time"  
                },  
                "end": {  
                    "dateTime": "2022-11-16T17:00:00",  
                    "timeZone": "Pacific Standard Time"  
                }  
            }  
        ]  
    },  
    "isOrganizerOptional": "false",  
    "meetingDuration": "PT1H",  
    "returnSuggestionReasons": "true",  
    "minimumAttendeePercentage": "100"  
}
