Export contact from Outlook to Zoho

Export contact from Outlook to Zoho

Hello,

I have troubles with the plug in.
1) I select contact in outlook
2) I use the export function
3) I can see contacts & account that have been created (not all the one I have selected)
4) I delete all created contact and acount in Zoho + empty recycle bin
5) I export again. Export noticed that many already exist !! And only part of my contact are created....

I'm stucked, please help....

NOTE : I need to fill the Leads from Outlook, not the contacts

Thanks
