Hi Veni,
Thank you for contacting Microsoft Community and we will be glad to assist you with your concern about updating index entries.
I would like to ask a few questions, for more clarification on the issue:
- How are the index entries inserted in the document?
- Press Alt+f9 and check if the field codes are available for index entries.
The Update Index option will be available only when you have placed the cursor on the index entries. If you have paced the cursor anywhere else in the document then the Update Index option will be greyed out.
I hope the above suggestions help to resolve your issue. If you need any further assistance reply and we will be glad to assist you.
Thank you.
