Microsoft Exchange Server: From the instant you create Microsoft Outlook account each and every folder will be stored in Microsoft Exchange Server database. The copy of the Outlook files and folders are stored in an offline data file i.e. OST in your system hard drive. When there establishes connection between Outlook and Exchange Server, the OST file synchronizes with this server.

What make OST file as Orphaned?

Even Exchange Server administrators face a situation like accidentally deleting the mailbox or re placing the user Outlook account. In such condition user find that the Outlook OST file is no longer usable and it becomes orphaned. Have look on some other reasons for orphaned OST file:

  • Hard drive failures at Exchange Server side may corrupt its database and makes respective OST files stored in it as orphaned
  • By chance if you unknowingly change MAPI or domain setting in Outlook, then the corresponding OST file become orphaned
  • The Messaging Application Programming Interface (MAPI) and your Outlook profile contain an encryption key, which helps at the time of synchronizing OST file with Exchange Server. If this encryption key is lost from both MAPI and mailbox, then OST file synchronization fails. In such scenarios, the OST files become orphaned.

Possible solutions:

One can even re-establish the synchronization between your Outlook OST file and Microsoft Exchange Server in order to make orphaned OST files into a usable one within two steps as follows:

  • Connecting the Outlook with original MAPI
  • Connecting that MAPI address to original Microsoft Exchange Server
