Trying to import opportunities from Dynamics 365

Trying to import opportunities from Dynamics 365

Hi, 
I am trying to import opportunities from Dynamics 365 and I am having the following problem in all the registers:
"Could not find a matching parent record for this lookup field. - Account ID"

I have exported accounts from already created ones in Zoho and copy the Account id in order to have the zoho code, for instance: 
zcrm_2723283000000235097

Can support help me with that?

Thanks,

Martin
