Outlook’s OST files aren’t directly supported outside of Outlook. Sharing specific contacts with others who use different platforms can become problematic. Therefore, to resolve this, the simplest solution is to convert OST to vCard (.vcf) format. The vCard format works with most email platforms, making it easy to import and share contacts. So, how does this import process work? This can be done in two ways: manually and with the help of a specialized Cigati OST to PST Converter. Read the blog to better understand both methods in detail. But before implementing the solutions, let’s first compare the OST and VCF formats.
Below are some of the key points to keep in mind to understand the important technical comparison between the two formats.
OST | vCard (VCF) |
Offline Storage Table | Virtual Contact File |
Stores full Outlook mailbox data. | Stores individual or multiple contact details. |
Outlook-specific | Can be opened in Gmail, iCloud, Android, iOS, etc. |
Stores emails, contacts, calendars, etc. | Stores only the contacts. |
Difficult to share specific contacts | Easy to share specific or bulk contacts |
The file size is large. | The file size is small. |
VCF files are compact and universally compatible with most of the contact management applications. This makes them an efficient format for managing and sharing contact details. The following are some benefits of doing this:
There are two primary methods for performing OST to vCard (.vcf) file conversion. Users need to use MS Outlook to perform the manual method. However, for a faster, more accurate, and error-free transfer, we recommend a professional conversion tool. Let’s start with the manual approaches first.
For this method to work, ensure that your OST file is connected and accessible in the Outlook application. This is suitable for those who want to export only a few contacts.
Perform the steps given below to begin the conversion process:
Limitations: This method saves only a single contact at a time. There is no option for bulk export. Also, this method will fail if your OST file is corrupted or orphaned. Manually exporting contacts one by one can become a tedious task and take a lot of time. Moreover, the process does not ensure data integrity.
Are you looking for an automated solution to convert OST Files to vCard files? The OST to VCF Converter is an advanced solution that protects the migration of emails, contacts, and attachments.

In this blog, we have covered both manual and automated methods to convert OST to vCard. Though the manual method is functional, it’s complicated, technical, and time-consuming.
