OST Extractor Pro’ is a sharp tool for OST to PST conversion from USL Software. It houses almost all the features that is required to extract data from OST files and to save it into PST format. Along with that, it can also recover your emails from OST and save them to Text, HTML, or RTF format, which can be prove to be very valuable in certain circumstances.

The ost to pst converter tool for Mac & Windows

OST Extractor Pro” also has a simple to use interface that makes the job easy even for beginners. Its interface has been designed to offer you advanced features without any overwhelming the non-experienced users. The wizard that guides you systematically at each step through clear instructions, easy enough for a basic user to follow, and gets the job with the least efforts.

Let’s take a look at two of its most valuable features in detail:

But before we do that, First, what are the reasons that could corrupt the OST files?

The most common reason is when a person deletes the office exchange account. Only an original exchange account can read the OST files. Thus, if you have deleted the exchange account which created the OST files in the first place, you will find your OST file inaccessible.

The other common reasons include the server issues. If the server is undergoing maintenance, it can render OST files unworkable.

Few other reasons are power failures, abrupt shutdown of the computer when the work was in progress, virus or malware attacks, and hard ware failures.

All these factors lead to inaccessibility of OST files. And if you are out of luck, you will also find them damaged to a severe degree. What’s worse is that there are no clear and tangible third-party solutions out there that could resolve it easily. There are some manual steps, which are very convoluted, time-consuming, and incredibly hard for even computer geeks.

But, you are not out of luck today. Because I am about to reveal a Windows utility that works wonderfully to resolve the concern of OST corruption. The impressive thing is that not only can it repair OST files but convert them into PST files. And, PST files are easily operable by Outlook by simply exporting them to Outlook database. And it’s known as “OST Extractor Pro.”

And now, let’s take a look at its two of the most important features:

Ability to Handle Large and Multiple OST files in Batch

There are many cases where more than one OST file is damaged or not accessible in Outlook for some reason. Then, it becomes too cumbersome to try to recover the data from each file one at a time. Most OST to PST converter fail miserably to offer batch conversion.

Even dealing with OST file that’s very large can be inefficient through conventional tools. OST is a complex data file format and dealing with large files and in bulk is tricky.

Thankfully, “OST Extractor Pro” has the required power and the algorithms that do not falter at batch conversion of large OST files. It can handle overly large OST files and you don’t need to process them one at a time. This is achieved without compromising the other factors like speed, accuracy, and such.

Accurate Recovery from OST to PST files

The most important part of any recovery is, well, recovery. What a user wants most is to recover the data from the damaged files, or to convert everything from one format to other, OST to PST in this case. It’s so important and the primary factor driving the success of OST to PST converter that a general user is willing to take risks and to tolerate other limitations like lack of speed, no support for non-English text, or no proper interface.

Yet again, “OST Extractor Pro” brings undeniably the most precise data processing algorithms that recovers data from OST to PST files without any missing items. It’s accurate down to the single byte of data.

For instance: emails can contain, and usually all email users will agree, images, attachments, non-English text, metadata, headers, and so on. All such information elements are very necessary and everyone needs them to be recovered.

OST Extractor Pro” has the extensive algorithms, powered by multi-phase scans, real-time effective data-handles, and other advanced processing logic, that in the end delivers 100% recovery and conversion rate. You will never find anything missing or not converted with full precision.

And to add to that, you get free lifetime updates, whenever they are rolled out.
