Lost Outlook Access but Contacts Are in OST File – Any Solution?

[davidclark11]

When Outlook access is lost, the main issue is that OST files are linked to the original Exchange account. That’s why Outlook doesn’t allow exporting contacts once the account is removed. Manual tricks usually don’t work in this case. The practical solution is to use a tool that can read OST files independently and convert contacts into a usable format like VCF. This is where an OST to VCF Converter becomes necessary, especially when Outlook is no longer accessible. I faced the same issue earlier and used TrustVare vCard Export Import, which worked reliably as an OST to vCard Converter and helped me move all contacts into VCF format without data loss.
