In this method, we will try to recreate the lost OST files. This process is applicable for Outlook 2019, 2016, 2013, 2010 and below versions of MS Outlook.
You should have to perform this process wisely, only if your OST file is not usable anymore. This method may help to repair the OST file but can cause some data loss.
