How to Convert OST Files to VCF Format
Converting OST (Outlook Offline Storage Table) files to VCF format using Aspose.Email for Java presents a convenient method for efficiently managing contact information. By utilizing the comprehensive features of the Aspose.Email API, developers can seamlessly parse OST files, extract contact details, and convert them into VCF format. This conversion process ensures that all contact information, including names, phone numbers, email addresses, and other relevant data, is accurately preserved in the resulting VCF files. With Aspose.Email’s intuitive and user-friendly framework, developers can effortlessly integrate OST to VCF conversion functionality into their applications.
To convert OST files to VCF format, the library offers the PersonalStorage class which is used to represent a personal storage file, such as an OST or PST file. It provides methods for opening, creating, and manipulating the contents of personal storage files. The FolderInfo class represents a folder within a storage file (OST). It provides methods to access information and messages contained within the folder. The StandardIpmFolder enumeration class defines standard folders within a personal storage file. In the code snippet below, it is used to specify the Contacts folder. The MapiMessage class provides developers with a comprehensive set of functionalities to work with email messages programmatically, enabling them to efficiently manage, manipulate, and interact with email data within their Java applications. With the MapiItemType enumeration class, you can define different types of MAPI items, such as emails, contacts, tasks, etc. In the code sample below, it is used to check if a message is a contact type. The MapiContact class represents a contact in MAPI format. It is used to save the contact information as a .vcf file. When saving a contact, choose the format with the ContactSaveFormat class. Overall, these classes are used together in the code snippet to open an OST file, iterate through the contacts in the Contacts folder, convert them to VCF format, and save them as individual VCF files in the specified output directory.

Steps to Convert OST to VCF via Java
Java programmers can easily convert OST file to VCF in just a few lines of code.
- Open the OST file by creating a PersonalStorage object using the PersonalStorage.fromFile() method with the path to the OST file.
- Check if the output directory exists, and if not, create it.
- Get the Contacts folder from the OST file using getPredefinedFolder .
- Iterate through OST messages.
- Check if the message is of type Contact with the MapiItemType.
- Convert the message to a MapiContact object using toMapiMessageItem method of the MapiMessage class.
- Save the contact as a VCF file using the save method specifying the format for the file and the file path.
System Requirements
Before running the Java conversion code, make sure that you have the following prerequisites.
- Microsoft Windows or a compatible OS with Java Runtime Environment for JSP/JSF Application and Desktop Applications.

Convert OST to VCF - Java
// Open the OST file
PersonalStorage ost = PersonalStorage.fromFile(ostFilePath);
// Ensure the output directory exists
new File(outputDirectory).mkdirs();
// Get the Contacts folder from OST
FolderInfo contactFolder = ost.getPredefinedFolder(StandardIpmFolder.Contacts);
// Iterate through OST messages and save contacts as .vcf files
int count = 1;
for (MapiMessage msg : contactFolder.enumerateMapiMessages()) {
if (msg.getSupportedType() == MapiItemType.Contact) {
MapiContact contact = (MapiContact) msg.toMapiMessageItem();
String vcfFilePath = outputDirectory + File.separator + "Message" + count + ".vcf";
contact.save(vcfFilePath, ContactSaveFormat.VCard);
System.out.println("Contact " + count + " saved as: " + vcfFilePath);
}
count++;
}
What is OST File Format?
OST (Offline Storage Table) file format is a file that stores a copy of mailbox items from an Exchange server, allowing users to access their mailbox data even when they are offline. OST files are synchronized with the Exchange server when a connection is established, ensuring that any changes made offline are updated on the server as well. OST files are used by Microsoft Outlook for email, contacts, calendars, tasks, and other mailbox items in an Exchange environment.
What is VCF File Format?
VCF (Virtual Card Format) or vCard is a digital file format for storing contact information. The format is widely used for data interchange among popular information exchange applications. Most operating systems such as Windows and MacOS come with default applications to create and open these files. A single VCF file can contain contact information for one or multiple contacts. A VCF file usually contains information such as contact’s name, address, phone number, email, birthday, photographs and audio in addition to a number of other fields. Being supported by email clients and services, there is no loss of data during the transfer of contacts via using the vCard format. The media type for VCF file format is text/vcard.
