X1 Search 8.5.2 Release - Build 6001si

I have just installed this version on a new Dell XPS 13 2 in 1 with Win 10 Pro. Everything indexes, and re-indexes on schedule, as it should but I seem to have lost Real Time Indexing on my Outlook PST and OST files. I have to exit and restart to get the index up-to-date. Any thoughts? No problems with RTI with this version on the machine I just changed from (Win 10 home).

Thanks.
