Hello @poovarasan d

This is an expected behavior any chances to recurrence property will reset the recurring event and any deleted/updated (exception occurrences) will be reset to master event again.

For example, simply updating subject, categories will not re-instate the deleted occurrences of the recurring event.

PATCH https://graph.microsoft.com/v1.0/me/events/{id}
Content-type: application/json

{
  "subject": "{updated meeting subject}",
  "categories": ["Red category"]
}

If you also include recurrence will not re-instate the deleted occurrences of the recurring event.

PATCH https://graph.microsoft.com/v1.0/me/events/{id}
Content-type: application/json

{
  
  "subject": "{updated meeting subject}",
  "categories": ["Red category"],
  "recurrence":"{....}"
}
