Hi @Avinash Yadav ,
This issue of automatic meeting updates or cancellations being sent from the Outlook app on Android has been reported by others as well. It seems to occur more frequently when the meeting invite is sent to a large audience.
In addition, if the user uses the "Sync Calendar" function in Outlook for Android, the meeting will be canceled unexpectedly. It is recommended that the user temporarily turn off this function to see if the problem continues.
