OST to PST Converter is a powerful tool that can convert multiple OST files to PST files. The tool can extract emails from .ost files without requiring Microsoft Outlook or a server account connection. This makes it a useful application in case of data loss, corruption, or inaccessibility of .ost files. However, Microsoft Outlook must be installed on your PC to create a new .pst file or exporting to an existing .pst file.
When you can open an .ost file in Microsoft Outlook, you can use it to export items by creating a .pst file. However, if you're using Cached Exchange Mode, Outlook will only export the items in your current cache. By default, Outlook configures Exchange and Microsoft 365 accounts to only synchronize the past 12 months of your email. Follow the export instructions to move your email from the .ost file to a .pst file. To export more than the past 12 months of data, turn off Cached Exchange Mode first.
If you encounter Outlook connection issues or cannot open your .ost file, use OST PST Viewer to open, export or backup emails from your .ost file. After your email data is exported to a .pst file, it's portable. You can save, backup, or open the converted .pst files on another computer.
If you're looking for a quick and easy way to convert your entire .ost file to .pst file, OST to PST Converter offers a simple one-click solution. However, if you want to preview and export selected items or search results from .ost to .pst files, use OST PST Viewer. If you need to convert OST to PST using PowerShell, try PstScan Pro.
Follow these steps to find and export specific selected items from OST to PST files:
The PstScan Pro can bulk convert OST to PST in batch scripts using PowerShell, Task Scheduler and other automation tools. To do this, use the command line options of the product.
cd "C:\Program Files (x86)\PSTWalker Software\PstScanPro"
$OSTFiles = @("c:\a.ost", "c:\b.ost")
foreach ($OST in $OSTFiles){
.\pstscanpro.exe convert pst -f "$OST" -p "D:\PST-Queries" --% -q:"from:(=bobbymoore@contoso.com OR ""bobby moore"")"
}
This example searches c:\a.ost and c:\b.ost mailboxes for items in which the e-mail address equals bobbymoore@contoso.com OR sender name contains bobby moore. The search results are exported to D:\PST-Queries\a.pst and D:\PST-Queries\b.pst
When running native commands from PowerShell, the arguments are first parsed by PowerShell. Beginning in PowerShell 3.0, you can use the stop-parsing (--%) token to stop PowerShell from interpreting input as PowerShell commands or expressions.
cd C:\Program Files (x86)\PSTWalker Software\PstScanPro
pstscanpro.exe convert pst -f c:\users\*.ost -p "D:\PST files" --srcfolders
This example convert all .ost files located in the c:\users folder to .pst files to the D:\PST files directory.
