Due to API limitations from Zoho CRM, we cannot support the export of the following:
Comments
Formulas
Emails. Please note, you can vote for this feature on the Zoho CRM Forums
We can export Notes and Attachments. However, due to the number of API calls required on the Zoho side, we do not export these during the sample import stage.
If you need Notes and Attachments to be imported, please send us a message and we can get that enabled for you.
