Zoho CRM - Importing previously exported Tasks

Zoho CRM - Importing previously exported Tasks

Hi,

I've just exported my Tasks from Zoho CRM. This gave me a nice CSV file with correct columns and data. I didn't modify it in any way.

Now I want to import these tasks into Zoho CRM.
Everything seems to be ok except one thing - after import there is no Task Owner assigned.

I've tried (in the import process) to set field for Task Owner to almost any (reasonable) column from CSV with no success. I thought that the column should be set to that with zcrm_6..some_digits...

How can I import previously exported Tasks?
