Sometimes, OST files of MS Outlook application are not synchronized with the MS Exchange Server. Now, what exactly happens is that, in the Cached Exchange mode, a backup of your Exchange mailbox is basically stored locally as an OST file. Now, sometimes, it happens that this OST file creates problem during the attempt to convert it into a PST file. In such an annoying situation, you come in the need to convert the mailbox data of OST file into PST file manually. Why is this required? This is required for updating the email contents of OST file and Exchange Server mailbox.

Causes for Above Errors Emergence: Some of the major reasons that are responsible for the occurrence of the above error messages are as follows:

• The above error message is mostly seen because of the fact that RPC encryption is needed in the default MS Exchange server 2010 RTM configuration whereas it is not used by Outlook 2003.
• When Microsoft Office Outlook 2007 is used and you somehow disable the Encrypt data between the Outlook and Exchange setting of profile.
• You see the above errors with unusable or orphaned OST files.
