Summary: For users and organizations relying heavily on offline MS Outlook, Outlook Storage Files (.ost) are very important. They store almost all the data of the Exchange within them, but when it comes to migration of contacts or other data, they lack. At such time, VCF (vCard) format is considered ideal to manage the Outlook address book data. Here, through this guide, find out the freeways and OST to PST Converter Tool to convert OST to vCard quickly and securely without hassle.
Since VCF is universally preferred and is compatible with iPhones, Android, Gmail, iCloud, and CRMs. It is appropriate for all situations, whether you need to import contacts between clients or switch devices.

But the real challenge comes with the extraction of OST file data. Since it is tied to the specific Outlook profile or Exchange/Office 365 account.
Furthermore, to ensure smooth OST to VCF conversion, a user must consider these tips before the process:

The manual method may still lack somewhere and have a few cons, since its free. But the professional software is expert tested and verified to provide 100% best results.
In this section, we discuss all the methods available for Outlook OST to vCard conversion on Mac and Windows. Follow the step-by-step guides mentioned below for successful results for free.
Note: Outlook only supports saving one contact at a time, and if done for many, the process becomes complex and time-consuming.
In this process, users need to first convert OST to CSV, and then change CSV to VCF. It is lengthy and tedious with not much guarantee. Still, the steps that execute the conversion are:
Part 1: Exporting OST Files to CSV
Use the built-in Import/Export wizard of the MS Outlook profile. Choose the Comma Separated Value format in it and extract contacts from the folder.
Part 2: Export Outlook OST Contacts to VCF from CSV
Once you have the OST file as Excel CSV, use the Windows Import to change it to vCard. The steps include:
Note: You can even do this by importing CSV to Google Contacts and afterward, exporting it as VCF.
Since Mac doesn’t directly support the OST file, first, change it to CSV or vCard following the above two approaches. Later, using an external drive, say, USB, AirDrop, or Email (Gmail), export contacts. Finally, access the VCF file within the Mac Contacts app.
When the manual ways to change OST to VCF seem a bit complex and a lot of hassle, then opt for the SysInfo OST to PST Converter Tool. Though the name suggests conversion to PST, it can export Outlook OST contacts to VCF, PDF, CSV, and many more formats at once. The tool needs no Outlook application and reliably moves bulk contacts of any size, including attachments, with full accuracy.

Case: Migrating 8,000+ Contacts from Inactive Exchange Mailboxes
Situation: An IT admin from a mid-sized marketing firm needed to extract contacts from multiple orphaned OST files after closing their on-premise Exchange server. The team had no access to the original MS Outlook profiles, and the OST files were locked in offline mode.
Analysis: Outlook doesn’t open the files directly, and manual import of such a large volume is not possible.
Solution: The team used the dedicated OST to VCF Converter Tool and exported all contacts to .vcf files in batch mode. It even kept metadata and other details preserved.
Result: The tool saved them over 15 hrs of manual work and also ensured 100% data consistency.

These offer cross-platform portability without additional costs, but are only ideal for individual and small teams. On the other hand, exporting for a large enterprise or for migrating OST from disconnected profiles, using the professional tool is the optimum choice.
Ans- Yes, if you use the OST File Converter Utility. Then, you can export any number of contacts from OST to a single VCF at no loss.
Ans- When using the OST to vCard Conversion utility, you do not need Outlook installation. It only needs your OST files stored on the Mac/Windows system. If you use the manual methods, then Outlook is mandatory to export OST to VCF.
