As soon as your OST file is synchronized with the Exchange server, you can easily access all the work done offline when you were not connected to the server. In the synchronization process, the Exchange mailbox is updated with all the changes that are made to the offline folder file. But synchronization may not always work correctly due to incorrect profile settings or corruption of the OST file. In such cases, the data present in the server folders does not match with the data in the offline folder file. To regain access to your valuable OST file data, you can try to perform OST To PST conversion using a reliable third-party utility.

Consider a real time situation. Suppose some of your friends decide to use cached Exchange mode due to a network connectivity problem. They come across the below mentioned problems while using the cached Exchange mode:

• MS Exchange Server computer crashes.
  
• Unusable OST file is connected to a new domain.
  
• Synchronization of Outlook OST file fails.
  

Cause:

The problem occurs while connecting the Outlook OST file to the new mailbox. This happens because the items like mailbox content, Outlook OST file, and MAPI (Messaging Application Programming Interface) profile of new and original servers must be same. The reason responsible for a failed synchronization is the alteration done in any of the above mentioned items.

Solution:

For resolving the above issue, try the below given suggestions:

• Create a new PST file and import data of the orphaned OST file into this file. In this way, the data can be easily accessed. You should follow this suggestion, if configuration of original MAPI profile of Exchange Server has been done.
  
• The best and reliable way to fix the above stated problem is to convert OST to PST. This can be easily done with the help of an effective third party OST to PST converter tool.
