One of the most effective ways to reduce the size of Offline Outlook data file (.ost) is to archive OST into PST. Be wary, though. Moving data from a large-sized OST file to PST increases its size and makes it susceptible to corruption. A better alternative is to split OST file into multiple PSTs.
There is no built-in utility for splitting large-sized Outlook data files (.ost). An alternate approach is to backup individual mailbox items from an Offline data file to a PST file one at a time using Outlook Import/Export wizard. But, this can be a tedious and time-consuming process, particularly when you need to split multiple OST files. Moreover, you cannot back up an inaccessible or orphaned OST file. This is where an OST to PST Converter tool such as Stellar Converter for OST Technician comes in handy.
