How to Convert Orphaned OST file in PST with Stellar Converter for OST?

OST is an Outlook data file that stores a local synchronized copy of mailbox items. The file is encrypted by default with MAPIEntryID GUID and thus, requires authorization from linked MAPI profile to allow access. If the profile is corrupt or deleted from the mailbox server, the OST file becomes inaccessible. Further, the OST file may turn inaccessible due to system crash, abrupt system shutdown, malware or virus intrusion, large size, etc. 

In such cases, you need an OST to PST converter software, such as Stellar Converter for OST to convert inaccessible OST files to PST format.
