Why is Outlook OST to PST conversion necessary for users?

[Data Recovee]

The conversion of Outlook OST to PST is necessary when one is not able to be able to get into their OST file since it has been deleted, the server has crashed, or due to system modification. Because the OST files are linked with individual Outlook accounts, they cannot be opened by themselves. Outlook OST can be converted to PST, which will enable the data to be portable, readable, and usable in Outlook, and in that case, it will be the best backup, migration, and long-term storage option.
