Hi Yeonju Park,
I have reproduced the issue from my end and observed discrepancies in the data not only for India Standard Time (IST) but also for other time zones such as Pacific Standard Time. It appears that the findMeetingTimes API is returning "AttendeesUnavailable
"or "Unknown
" for emptySuggestionsReason even when there are available meeting slots.
Given these inconsistencies, it seems to be an issue in the API. You can submit feedback which will be monitored by Microsoft team and make the enhancements to Microsoft Graph APIs.
Hope this helps.
