I imported some 60.000 contacts and tried several times to re-do the import of Accounts/Contacts, with mapping to

AccountNAME, which is in the CSV file. After checking the CSV files DOES HAVE ALL THE FIELDS of 

Account name and Contacts,first/lastname. I use separate CSV files for Accounts and Contacts.

I do each time 22.000 import,(because of filesize) first the Accounts and the second import of Contacts. Everything OK after 3 x imports

3x22000.

Everytime after all imports there are some 1500 Contacts WITHOUT Accountnames. ........Zoho helpdesk said,

export those 1500 via Reports and re-import that file again.But it does not work.,tried several times.

What I do now is doing it Manually,because I have in Contactfile also a "Shadow" CompanyC field,which I

cut and paste in the 1500 file to the empty AccountName. THAT IS WORKING FINE, BUT TAKES ME a week,

to do all that manually, no problem, but a lot of time.

To verify I did a same import in to HUBSPOT(total 60.000 in one run) and then no problem,every Account with the underlying Contacts..

So what could be the problem with this ZOHO import, the remaning 60.000 minus the wrong 1500 is imported

correctly, so some 95 percent of import is working as it should be.

Thanks for helping me...
