EdbMails OST to PST Converter: Best solution for orphaned OST files


The OST file format is used by Outlook to store a synchronized copy of mailbox items on a user’s computer. By default, the file is encrypted with the MAPIEntryID GUID, making it impossible to open without the permission of an associated MAPI profile. The OST file becomes inaccessible if the user’s profile has been corrupted or erased from the mailbox server online. Additionally, the OST file may become inaccessible as a result of a system breakdown, an unexpected Outlook shutdown, an infection with malware or a virus, or simply because it is too huge.
