No Zoho Mail add on in Zoho CRM

No Zoho Mail add on in Zoho CRM

Hello,

As we have recently changed our organisation wide email servers, I would like to update our email settings in Zoho CRM, however I do not have the Zoho Mail add on listed when using the following location in Zoho CRM: Setup > Apps & Add-ons > Zoho Apps > Zoho Mail

(Only CRM analytics and and Zoho Projects add-ons icons exist, as per the screen print)

I am a paid Zoho mail and CRM subscriber - Can you please help?

Kind Regards
Fred
