That usually happens because Outlook saves contacts in a format that Samsung devices can not fully read. If you export contacts from Outlook as CSV , Samsung phones do not support that file type directly. And if you export as vCard (VCF) Outlook often creates a version with fields or encoding that Android doesn’t interpret properly. The result is contacts showing up with missing names, broken numbers or unreadable characters. The fix is simple: convert your Outlook contacts into a clean, standard VCF file first. A tool like
Softaken CSV to vCard Converter can take the CSV export from Outlook and convert CSV contacts to VCF. With
bulk CSV to vCard conversion, you can transfer all your Outlook contacts at once , fully readable on Samsung devices.
