We have currently used zoho desk for our ticket as we use a lot of zoho application and we might as well try the Zoho desk ticketing, 

Now we have come up with a bit of trouble setting it up. 

We have configured the channels for social and is working great. now for the email, we are having a bit of difficulty; 

when we go to setup->email

it shows this page

Then when I input a domain it will show this Insufficient Privileges to perform ....... page

Hoping you could help me with this issue. 

Thank you very much,

Carlo
