It allows the user to work in offline mode and scheduled any task whenever connection will stable with the machine. Nowadays, an MS Outlook is necessitating for E-mail conversation, schedule appointment, fix meetings with clients. An Outlook stores the client’s data in two file formats named as .OST and .PST.

An Outlook OST file is an offline storage data file that permits Outlook clients to work even when not linked to the Exchange server, i.e. in conditions when access to the mail server is not accessible due to any technical issues. An OST file in offline storage table file and create in two types of scenarios. The first one is with exchange server when cash exchange server mode is enabling during configuration of Exchange server email account with any MS Outlook edition and the second method is when email account configured with Outlook 2013 and 2016 by using IMAP.

Here are some causes, when OST to PST conversion is necessary

  1. When Exchange server is under maintenance or downtime, then MS Outlook user cannot access mailbox and the complete data of mailbox is store in OST file which executes with synchronization with Exchange Server. For getting the OST mailbox data, the user has to export that data in PST format.
  2. When Exchange server crashed due to many circumstances as virus attack, power cut and malicious software and the user will be unable to access OST file then he needs to OST to PST conversion.
  3. Deletion of user mailbox from Exchange server, OST file becomes orphaned.

The OST to PST conversion task has been a very general necessity of the MS Outlook users, who have need to migrate from one place to another place, or when they face OST file corruption concern that are given above. The major drawback of this data file is that user can’t access its data by copy-pasting it to other machines. If you want to export NSF to PSF file then it can be easier compared to OST.

 “How to access corrupted Outlook OST data?”

So for this concern, you don’t need to take lots of tension. I am going to describe you two simple methods for using OST file in another machine or any other Outlook version.
