Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
What size is the PST folder?
Approximately how many items originally needed indexed?
How many items are remaining still to be indexed?
You can ignore any automated offers for remote assistance, and we can reply back and forth here instead.
Was it 75,000 items initially, or are there 75,000 remaining to be indexed?
75,000 items could take around 6-8 hours to index.
Ok, and how many items are remaining now?
