Converting OLM files to VCF format is beneficial for those looking to extract and organize their contact information stored in Outlook for Mac. OLM files contain a variety of data, including emails, calendar events, and contacts. By converting OLM contacts to VCF format, users can easily transfer and access their contacts on a variety of devices and platforms. VCF files are widely supported and enable seamless integration and sharing of contact information across different platforms. This conversion process provides users with a convenient and efficient way to manage and utilize their contact information effectively.
Aspose.Email for Java is a powerful API that provides comprehensive functionality for working with email messages, contacts, calendars, and tasks in Java applications.

With the OlmFolder class and its methods, you can access messages within an OLM file 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. The MapiItemType class provides types for different MAPI items like email, contact, task, etc. The purpose of this class is to identify the type of MAPI item being processed. 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. The code sample below demonstrates the work of Aspose.Email classes to extract contact information from the OLM file, convert it into VCF format, and save it as individual .vcf file in the specified output directory.

int count = 1;
for (MapiMessage msg : folder.enumerateMapiMessages()) {
// Check if the message is a contact
if (msg.getSupportedType() == MapiItemType.Contact) {
// Save contact as .vcf file
MapiContact contact = (MapiContact) msg.toMapiMessageItem();
contact.save(outputDirectory + File.separator + msg.getSubject() + ".vcf", ContactSaveFormat.VCard);
