Zoho Book verified email address

Zoho Book verified email address

Hi, hoping someone from Zoho can help on this one. 

In Book have addded and verified an email address to be used in a custom function.  

However, when executing the function get banner warning of only admin, user or verified email can be set as sender address in sendmail function. 

Multiple email back and forwards with support and 8 days later still unable to send. 

Seems such a simple issue, but will save our team literally hours per week on sending remittance emails. 


Many thanks!
