SysTools OST Converter – Description & Specification

Let’s start with what SysTool OST Converter does and the promises made by the company.

So, what is OST Converter?

SysTools OST Converter is a document conversion software that can convert any OST file into multiple emails and document formats.

Document conversion software is a program we use when we transform images from JPEG to PNG, when we need to convert an audio file from MP3 to WAV, and when we need to change the video type from AVI to MP4.

Similarly, the OST Converter by SysTools is software that can convert OST files into numerous formats.

It can convert any IMAP/Exchange/Hotmail/Office365 OST file into PST, MBOX, MSG, EML, EMLX, and NSF email formats.

Moreover, you can export the OST file to other document formats: PDF, vCard, TXT, ICS, CSV, HTML, MHT, RTF, DOC, and DOCX.

Sometimes, we find the OST file is orphaned or corrupted, or we do not have access to the IMAP/Exchange server.

For example, when an employee leaves the company, we need to convert the OST data into other formats, when a company changes the Exchange server, and when an organization needs to archive the data.

But, with SysTools OST Converter, it is irrelevant whether the OST file is orphaned, inaccessible, corrupted, or oversized. It can easily convert such OSTs into the desired format.

Not only that, but SysTools OST Converter can extract and transform the S/MIME and OpenPGP encrypted OST files without hassle.

Furthermore, the SysTools OST Converter is functional on all MS Outlook versions and supports all Windows OS.

Performance of SysTools OST Converter

We all have dealt with the mismatch between what a company claims and what the product can do.

It is an annoying business practice that a company claims and bluffs and the product don’t meet the standards.
Therefore, I have put SysTools OST Converter through various trials.

In this section, I have recorded the performance of the SysTools OST Converter on different aspects and matrices.

Let’s begin.

Error-Rate in Conversion

This matrix calculates the average output error per a fixed set of conversions.

I have considered 100 exports for each format.

In each export, I exported 10 OST files.

The total exports add up to 1600.

And the total number of errors observed is 2.

Accordingly, the aggregate error rate is 0.125%

SysTools OST Converter can safely and successfully convert any OST file into multiple formats and faces only 0.125% errors.

Time Taken to Convert OST File

This matrix calculates how long it takes to convert an OST file into other formats.

Important: The time taken for conversion heavily depends on the system configuration. If you have a higher-end system, you should expect less time than one with a low-end computer.

My system specification: I use a 10th Gen i-7 with 8GB RAM and a 1 TB SSD for Harddrive.

The average time observed is 49 secs for an OST of 1GB.

SysTools OST Converter can convert different OSTs into other formats in 49 more or less.

Customer Support

No product is successful without good customer support.

The features, specifications, and performance play their part, but when the product starts to fail, the only solution is to reach customer support.

So, how good is the customer support for SysTools OST Converter?

Foremost, the measurement for this matrix mostly comes from experience with customer support.
Moreover, the assessment is not free of subjectiveness.

But, one aspect is quantifiable, I can determine the average duration of the response.

And that’s what I did.

I contacted them through all the available means: Live chat, emails, and phone calls.

And, every time, I inquired differently.

So, what was the result?

The response was adequate: the respondents calmly listened to what I had to say before suggesting me a solution. They were respectful toward me throughout the whole experiment.

And the response time averaged only 2 mins.

As a result of that experiment, I can say that SysTools OST Converter has a reliable customer support team.

Benefits and Limitations of SysTools OST Converter

Please Note: All the Benefits and Limitations are according to my observations.

Now, let’s look at the practical benefits of using the SysTools OST Converter.

Simple User Interface: The UI design is simple and easy to navigate. SysTools OST Converter is built in a way that anyone can quickly get accustomed to it.

Stable conversions: After measuring the performance of the SysTools OST Converter, I can say it has close to no errors, and you can enjoy stable and intact conversions.

Virtually No Limit: SysTools OST Converter can import/export as many files as you want in one session. No need to stress about how many files to convert at a time.

Lifetime access to the Tool: When you purchase SysTools OST Converter, you get a lifetime license for the product. It means never thinking about the renewal and using the software with complete freedom.

Now we’ll see the short side

I have only one problem with SysTools OST Converter: it is unavailable for Apple users.
