A big advantage is that an Outlook OST file is maintained centrally on the mail server. Consequently, you can access your accounts no matter where you are or on your device. Only the cached OST files are erased if your system is damaged; the data backed up on the mail server is unaffected. To restore lost OST files, just reconfigure the Outlook account and sync it back to the device in question. This indicates, however, that OST files cannot be accessed without an Outlook account. ‘Orphaned’ OST files that belong to deleted accounts or are connected to data on another device must first be converted and exported using a recovery application to be retrieved.
