OST to PST, EML or MSG Conversion is Quite Simple with OST Recovery

osttopstMicrosoft Outlook comes with features that enable sustaining data for longer duration in the form of archives. However, the feature is applicable on Outlook’s default data file; PST. When in connection with Microsoft Exchange Server, users are given the option to create a local replica of their mailbox to be able to work even in offline mode, i.e. not in connection with the server. Later this replica can be synchronized with the server to update the data on server that was generated when in offline mode. This replica is created by enabling Exchange server Cache Mode in Outlook and is called Offline Storage Table, better known as OST file. This blog will introduce users with the requirement for conversion of this Exchange mailbox offline mailbox replica.

What Makes OST File Conversion Necessity?

The problem with this kind of file is that, maintaining it for long term purposes is both risky and sometimes not possible as well. Let us take a look at the whole scenario for a better understanding of the same.

Firstly, the offline storage files are just a temporary storage. The data in this file remains in synchronization with Exchange Server mailbox. Thus, any accidental removal of email or other items that take place on the Server mailbox automatically reflects back on its local replica. Thus, loss of data cannot be balanced with the mere existence of the OST file as, once synchronization takes place, the same data is also removed from the file.

Secondly, an OST file being a local cache of the Exchange mailbox only works in connection with it. The OST file is bound to its own respective mailbox and will only work when the keys of both the mailbox and OST must match in order for them to sync.

Converting OST File without Data Compromise

The Exchange OST file can be converted to an independently accessible file like; Outlook PST which doesn’t come packaged with as many limitations as with an OST file. Though the transfer of OST data file to a PST is feasible manually but due to technical hurdle like; delay in transfer due to large number of items, too much of end user efforts required, etc.

Relatively, a commercial utility works better at such tasks with the ability of dealing tactfully with data file of any size, in any state (corrupt, healthy, or orphaned), etc. OST Recovery successfully serves the purpose in the required manner. Moreover, the tool can also convert the data of OST to EML and MSG format files apart from Outlook PST.


Why OST File is Essential for Outlook/Exchange Server Users?

What is an OST (Offline Storage Table) File?

It allows you to use on the cache mode Exchange Server to read emails with mailbox when connectivity loss between Outlook and Exchange Server.

How to create an OST file by default?

In other hand a copy of the Outlook mailbox is created on your computer in format of Offline Storage Table (.ost) file. If OST file is synchronize with Exchange Server when connection is available. If you got error message during synchronization process it means connectivity lost between Outlook and Exchange Server.
