Robust Software to Convert OST Files into PST Formats

Stellar Converter for OST provides a host of utilities & tools which make it possible to convert existing OST files into the more accessible and user-friendly PST format. This is the preferred solution if a user experiences an email failure or issues associated with synchronization and wats to locally access his emails. A free trial version of this bundle is available for evaluation. 

Conversion Software to Address Multiple Potential Issues 

This type of software will often be deployed when problems with MS Exchange suddenly occur. Common scenarios include (but may not be limited to) deleted accounts, hardware failures or the presence of a virus. The primary issue is that during such situations, it can be difficult (if not impossible) to obtain a copy of critical OST data files. Stellar has offered an integrated and powerful solution. Any information within the MS Exchange mailbox can be successfully extracted and converted into a more accessible format. This information is thereafter able to be exported to Microsoft Outlook. In other words, the data can be accessed as opposed to remaining essentially "locked" within a failed MS Exchange system. 

A Clear User Interface and Efficient Functionality 

First and foremost, this Stellar Converter is compatible with many versions of MS Office such as 2016, 2013 (both 32- and 64-bit), MS Office 2010 and MS Office 2007. There are several additional user-friendly features associated with this bundle. Batch conversions are available; ideal if a massive network failure has occurred and time is of the essence. It is possible to choose the location of the file and to view an aggregated list of those which are currently associated with the OST format. Once the appropriate files have been selected, the conversion process will begin. Please note that the completion time will depend upon the sizes of the associated files. It is likewise possible to choose the location where the converted PST bundle will be saved. All options are clearly displayed and if a question arises during the process, a help icon is located at the top of each page. 

More Than Meets the Eye 

Although the standard tools associated with this converter are impressive, there are additional utilities to note. Existing files can be modified to work with the Office 365 format. Assuming that a PST file is extremely large, it can be split into multiple components for faster processing. Any information can likewise be scanned and saved in the form of a DAT file. This is a great option if there is not enough time to complete the conversion process within a single session. Additionally, repeat scans will not be required. All Windows operating systems beginning with Windows XP are supported. 1 GB of RAM is required and at least 100 megabytes of hard drive space will be necessary.
