Dear Jagdeep,
thanks for posting this question as well as a possible solution. Unfortunately, when I open one occurence of a meeting series I don't see the "Edit" button at the buttom left corner of the event. What version of Outlook were / are you using in the screenshot?
But I have another solution what is from my understanding the more generally working approach. Instead of using the fat client of Outlook, simply access via Outlook Web Access (you can find the direkt url under ribbon "File" right at your "Account Settings". In the web view simply navigate to the desired meeting occurence in your calendar and you'll find exactly those three options from your screenshot.
Hope, that solution helps even more people.
Best wishes,
Matthias
