OST to PST Converter Customer Reviews 2023

Rated 4.7/5 based on customer reviews

"I had a client with an IMAP email account that she used in Microsoft Outlook. The computer became unbootable, but I was still able to recover the OST file from it. On a different computer, we re-synched the IMAP account, but needed to recover the calendar and contact items from the OST file. Since Microsoft doesn't include an OST import tool (similar to PST), I was happy to come across the CoolUtils OST to PST converter. It worked well, but it would have been even better if it also recovered the full calendar items, rather than just the calendar headings. In the end my client was happy, so I can't complain. The price was very reasonable as well."

"Your tool was the only one to safely recover unusable files of OST. Now I have the regular PST, and I am happy with it. Thank you."

Comparison of the Formats

Microsoft Outlook uses two formats to store data. Users often need to switch between them, which makes tailor-made systems that convert OST files popular. These utilities allow hassle-free import and export. So, why are these different formats necessary, and how are they connected?

PST is the standard for different groups of mail accounts (web-based systems, IMAP, and POP3). Web-based systems also create PST files. PSTs are not linked to the Exchange Server, so they are portable. The other format requires a connection to the Exchange Server.

An OST file is a replica of the data saved on the Exchange Server. It allows you to work while disconnected and sync up the changes with the Exchange folder afterward. If the connection fails or the system crashes while you are composing emails, an OST file appears. This allows you to rescue the data and use Outlook offline. Thanks to the OST file, you can retrieve Outlook data after interruptions. Sometimes, these files become unobtainable via Microsoft Outlook, which disrupts work. In an office environment, such situations are particularly frustrating, and they require the use of an offline OST to PST converter.

OST files, on the other hand, may only be opened by the same system that created them. They store information on your hard drive and work in unison with PST data. Thus, system migration becomes the most fundamental motivation to convert from OST to PST. But why would you attempt to convert Outlook OST files to PST files?

Why Change from OST to PST Format?

One may transform data into different formats easily using Total Outlook Converter. So, why convert from OST to PST? Reasons vary, but professional utilities will handle the task regardless of its purpose. Typical situations for the conversion include the following:
  1. The Exchange server malfunctions, which makes the use of OST impossible unless you convert OST to PST;
  2. The above-mentioned server is under maintenance, which also makes OST data unobtainable without conversion;
  3. Connection to another Exchange Server due to workplace change: OST files may only be opened by the system that created them, so you need to initiate the file conversion;
  4. Migration of data requires the conversion of one or multiple OST files to PST format;
  5. Recovery of information: Through immaculate conversion, you can even restore data deleted from the Exchange Server;
  6. Severe corruption of source data that you can remedy with an OST to PST switch.
This conversion issue is more common than you may think. Any active user of Office 365 may need to transmute Outlook data sooner or later. In all of these cases, accurate conversion to PST format is the only way, and the best method to achieve this is with an offline OST to PST converter. While different utilities that convert OST exist, it is essential to use a professional tool that guarantees a flawless transformation and will create a new PST file properly.
