Outlook .ost file Outdated - Delete and Recreate
« on: November 04, 2017, 10:30:46 AM »
Hello All,
Recently, I replaced the hard drive on my laptop with a larger drive.
For the record, I backed up the first hard drive using Acronis True Image and then restored it to the larger drive
The move was successful until I opened Microsoft Outlook 365.
That program advised that I was running an outdated version of the .ost file asking me to close Outlook and delete the .ost file
Unfortunately, Outlook offered no clue as to where that file was located or how to delete it.

I searched on-line for guidance.  Finding nothing useful, I tried my own hand at solving the problem.

I have posted on YouTube the steps that I took to successfully delete the Outlook 2016 .ost file and have Outlook recreate a current version.
