pst file restore Outlook 2013 from HTC One M9

I use my Surface Pro to work with Outlook 2013, then copy outlook.pst file from my Surface Pro to my desktop and sync my contacts and calendars with my HTC One M9 (android phone) using HTC Sync Manager from my desktop, I been doing this over a year as a safety measure. Unfortunately, my Surface Pro is broken down, so I use my desktop to work with Outlook 2013 and sync my original outlook.pst file directly with my HTC One M9, so I don't have anymore a backup outlook.pst file in case something happen during the sync. Well, now something happens and the sync application duplicate my contacts on my outlook.pst file of my desktop and mess the views on the contacts (people tab), too.
Maybe, I will be able to work around it, but it will take me a lot of time wasted and effort.
I want to know if there is a way to recover my last version, before sync.

Unless you made a copy of the pst, either copying it or using backup software, no, there isn't a recent copy. Try adding the Modified date field to the view and sorting by it - do the copies all have a different modified date than the originals? If so, sort by the last modified date and delete the copies.
