MS Exchange Server allows configuration of Outlook account that creates an Offline Outlook file, OST enabling its user to work in offline mode. Since Exchange binds the OST file to a particular MAPI profile, it can only be accessed on the Outlook profile on which it was created. Due to this reason, OST file is very much prone of getting corrupted or orphaned. In the blog, we will be studying on how to access Outlook Emails from Orphan OST files.
What makes OST files orphaned?
Some of the reasons that could make the OST file orphaned are as follows:
Unintentional Deletion or Dismounted Exchange Mailbox : If the mailbox on the Exchange Server on which the OST file was originally created is deleted or disabled by Server Administrator, the contents of that OST file becomes inaccessible and thereby making it orphaned.
Virus Intrusion on the System : Another reason for making OST files orphaned is due to virus or other malware attacks on the system that could infect/damage the databases of Exchange Server. It will make the mailboxes unusable leading to the orphaned state of OST files.
Destruction of Storage Location : If the storage media such as hard disk contains some bad sectors, on which the Exchange Server databases was stored, then some part of the database file can become unreadable, making the OST files associated orphaned.
Abnormal System Shutdown: If the unexpected power failure interrupts while carrying out the synchronization process with OST file and Exchange Server, it will damage the databases & can make orphan OST files.
