Question:

Why is the size of a converted PST file smaller than the size of the original OST file?

Answer:

Our engineers have analyzed the content of OST (source) and PST (destination) files. The analysis revealed the types of data that are not carried over to the PST file after OST file conversion:

1. old versions of messages, contacts, files and other objects
2. removed objects
3. blocks of data from earlier versions of messages, contacts, files and other objects. It is impossible to use these blocks to fully recreate the original object, which is why they can be treated as junk.

In other words, when you remove or modify a message, contact, reminder or meeting, the object is only marked as removed, but is not removed physically and remains in the OST file. The new version of the object is written to a newly allocated space, but the old version remains in the OST file as well.

If Outlook is in active use, the size of the OST file can grow quite significantly, while the actual size of data in the file remains the same.

In order to optimize disk space consumption and remove old elements, you need to configure the AutoArchive feature in Microsoft Outlook.

Note: it is recommended to backtrack the changed options after the export of the recovered data in Microsoft Excel has been completed.

• search for and reading of old versions of documents is used by attackers for stealing users’ confidential information;
• search for and reading of deleted and old versions of documents is used by police authorities to collect compromising information (Forensic Mode);
• Recovery Toolbox for Outlook enables the user to search for data deleted from an OST/PST file and save it to the disk.

Question:

How do you convert a large OST file (over 4 GB) to a Microsoft Outlook PST file?

Answer:

When converting large OST files (4 GB and above), you will have to use a 64-bit computer system. All program components required for converting OST to PST must be 64-bit. These include:

1. Microsoft Outlook 64-bit
2. Microsoft Windows 64-bit
3. Recovery Toolbox for Outlook versions 4.0 and above

This allows you to bypass the limitations on the RAM that can be used by each component and convert OST files of virtually any size.

Converting huge OST files to PST files

Once all necessary components have been installed, run Recovery Toolbox for Outlook and perform the following actions:

1. choose the OST file you need to convert on the program's first screen
2. choose Convert on next page of Conversion Wizard
3. choose the emails, contacts, and other information you want to transfer from the OST to the PST file
4. choose the option to save as a PST file
5. type or select a folder to use to save the data on the disk

The process of reading the OST file and then exporting it to PST takes a significant amount of time. The time it takes to convert OST to PST depends on your computer's performance, particularly the speed of your disk subsystem.

Note: When you install Microsoft Office or Microsoft Outlook, the 32-bit version is installed by default. To install Microsoft Outlook 64-bit, read the following article: How to Install Microsoft Outlook 64-bit?

Question:

How to repair a large PST File with Microsoft Outlook Data?

Answer:

To recover a very large Microsoft Outlook PST file (more than 4 GB), you'll need to have Recovery Toolbox for Outlook installed on your computer, as well as the following:

1. Microsoft Outlook 64-bit
2. Microsoft Windows 64-bit

If you have the installation disc or distribution kit, you can install Microsoft Outlook 64-bit along with the 32-bit version of Microsoft Outlook. You'll find instructions for the installation of Microsoft Outlook 64-bit here: How to Install Microsoft Outlook 64-bit?.

Question:

I'm trying to recover a Microsoft Outlook data file. Your tool initially finds 40,456 objects, but the recovered pst file contains 40,337 objects according to the program report. What happened to the missing 119 objects?

Answer:

Microsoft Outlook data files contain main objects ( messages, contacts, notes, reminders, attached files and others) and service objects that are not shown to the user. While writing the recovered data to the new .pst file, the program does not write some service objects because there is no need to do it.

Question:

Whenever I try to import that recovered data, I get a message saying the pst file is not compatible with this version

Answer:

You performed the recovery operation at another computer or where another version of Outlook is installed. Our software uses Outlook components to compile the structure of a new PST file(s). So the recovered PST file is compatible with the version of Outlook that is installed on the system where the PST file was recovered.

Question:

Can your software recover old Outlook files that were on an old hard drive that crashed?

Question:

How to repair Exchange Server mailboxes?

Answer:

Repairing mailboxes after the corruption of the Exchange Server database file.

If the Exchange Server database file gets damaged, the server will still have *.edb files with users' emails. There will also be .ost files on users' computers containing the personal data of each user.

OST files can be quickly and easily converted to PST files using Recovery Toolbox for Outlook.

You can try recovering .edb files using Recovery Toolbox for Exchange Server. This tool converts individual mailboxes to .pst files.

We recommend trying both recovery methods to recover as much data as possible.

Question:

How to convert ost to pst file?

Answer:

This OST-to-PST converter is an easy-to-use tool that operates like a wizard. With it, you can convert an .ost file to the .pst file format in a few simple steps. No special know-how is needed in order to use the Recovery Toolbox for Outlook OST-to-PST converter.

Microsoft doesn't currently offer a special Outlook OST-to-PST converter. All OST2PST converters have been designed by ISVs. Recovery Toolbox for Outlook, however, has a demo mode that lets you convert five objects per folder.

Question:

What versions and types of .ost files can be converted to .pst files?

Answer:

Recovery Toolbox for Outlook can read *.ost files any versions of Microsoft Exchange Server, any version of Microsoft Outlook (32- or 64-bit, ANSI or UNICODE). Software can read and convert *.ost files with any size of file.

Question:

Why size of result pst file smaller than size of source .ost file in several times?

Answer:

The size of the converted .pst file shows the actual size of information stored in the ost file. If you do not make archives and do not start Cleanup Tool regularly for the original Offline Storage Folders, then the .ost file size is only growing. As a result, only 5-10% of the file can be used for a real user's data.

Question:

What version of pst file will be after OST2PST conversion?

Answer:

For the use of OST-to-PST conversion on a computer running Microsoft Outlook, the .pst file version will be the same as that installed in Microsoft Outlook. If the computer has Microsoft Outlook 2007 or higher installed, the size of the resulting .pst file can exceed 2Gb. If you use MS Outlook 98-2003, the size of the resulting file will be limited to 2Gb. In this case, Recovery Toolbox for Outlook will create several .pst files in which to store all the data from the source .ost file.

Question:

How export data from .ost file to other Email client software

Answer:

Recovery Toolbox for Outlook exports messages, contacts, appointments and other data from *.ost files as MSG files. The software converts and saves all data from .ost files to the .msg file format. Later, the user can drag and drop or import the saved *.msg files in any of the popular client software programs, including Lotus Notes, Microsoft Live, The Bat, Eudora, Incredimail, Mozilla Thunderbird, etc.

Question:

How do you import .ost files in Outlook?

Answer:

Microsoft Outlook has no function with which to import data from *.ost files. To open an *.ost file in Outlook, the Exchange Server and Windows Domain Controller must be working and available for user authentication in both of the respective services. Only after that is it possible to transfer the contents of an .ost file that is open in Outlook to a .pst file that is also open in Outlook.

If the Exchange Server or Windows Domain Controller isn't accessible or doesn't work, or if the user can't be authenticated, access to the data will be denied and Outlook won't open the .ost file.

Question:

How do you import data from an .ost file in Outlook when the Exchange Server or Windows Domain Controller isn't accessible?

Answer:

The original .ost file must be converted to a pst file using Recovery Toolbox for Outlook and then opened in Outlook. Conversion from OST to PST using Recovery Toolbox for Outlook doesn't require the availability of Exchange Server or Windows Domain Controller.

Question:

What is the maximum file size for multi-volume recording?

Answer:

There is no limit to the file size for multi-volume recording. However, the multi-volume recording feature is designed for recording large amounts of data on computers with older versions of Outlook (versions 97-2003) where the file size is limited to 2 GB. Thus, by splitting large files into multiple volumes, you can save all recovered data even on older computers with older versions of Microsoft Outlook.

Question:

How does the utility work with Unicode and ANSI PST files?

Answer:

Special algorithms determine the version of the PST file: Unicode or ANSI. Based on this, data is read from the PST file.

Note: Very often, after ScanPST utility failures, you have to recover PST files in which some of the data is recorded in Unicode format and some in ANSI format. Recovery Toolbox for Outlook recovers PST files even if the ScanPST utility has repeatedly recorded data incorrectly in different formats.
