# OST2PST
A while ago I needed something to convert a 5GB Outlook OST file to PST format. Turned out [Aspose](https://products.aspose.com/email) has a good (commercial) API/library for Java to do exactly that. I had not touched Java for 10 years but got things sorted within a few hours thanks to clear instructions and good examples and docs. I just used the example and made minimal changes, nothing more.
[**Saving to Outlook 2013/2016 PST files is not supported**](https://docs.aspose.com/email/java/read-and-convert-outlook-ost-file/#converting-ost-to-pst)
## Download
Get files below or from [Releases page](../../releases/latest)
**Jar and wrappers:**
* Main executable: [ost2pst.jar](ost2pst.jar) (verify [SHA512SUMS](SHA512SUMS))
* Windows batch file: [ost2pst.bat](ost2pst.bat)
* Linux/BSD shell script: [ost2pst.sh](ost2pst.sh)
If you need to install Java use your OS package manager or download it here: [JRE8+](https://java.com/en/download/manual.jsp) or alternatively [JavaSE-RE-8+](http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html).
### Usage
* Windows: `ost2pst.bat `
* Linux: `ost2pst.sh `
Or run the jar directly: `java -jar ost2pst.jar `
_Remember you need to have at least JRE8 installed, OpenJDK is untested but should work_
### Example
``` batch
C:\src\ost2pst>ost2pst.bat input.ost output.pst
OST2PST (210619)
INFO: File format is "64-bit Unicode" (23)
INFO: Loading file "input.pst" (5GB)
Folder [00] "Public"
Folder [01] "Inbox"
Folder [02] "Outbox"
Folder [03] "Sent Items"
INFO: Converting "input.pst" to "output.ost" 511MB/4751MB (11%) |
```
## Building from source
### Import into [Eclipse](https://www.eclipse.org):
* [pom.xml](pom.xml)
* [LoadAndConvertOSTFileCLI.java](src/main/java/com/ost2pst/LoadAndConvertOSTFileCLI.java)
### Get Aspose.Email for Java API/lib (*required*)
* [GitHub Aspose Email-for-Java](https://github.com/aspose-email/Aspose.Email-for-Java)
* [docs.aspose.com Installation (Maven)](https://docs.aspose.com/display/emailjava/Installation)
* [docs.aspose.com Aspose.Email java for Eclipse (Maven)](https://docs.aspose.com/display/emailjava/Aspose.Email+Java+for+Eclipse+-+Maven)
### Create runnable Jar in Eclipse
* use Ant to 'Export', 'Java', 'Runnable JAR file' (used for [ost2pst.jar](ost2pst.jar))
* or alternatively use Maven to build project
## TODO
Add new option that tries to read corrupted ost/pst files. See [here](https://docs.aspose.com/email/java/aspose-email-for-java-20-10-release-notes/#reading-corrupted-pstost-files) for more info.
``` batch
C:\src\ost2pst>ost2pst.bat -c broken.ost
```
