Zoho Mail not in Zoho CRM

Zoho Mail not in Zoho CRM

Just recently our Zoho Mail tab disappeared from the Zoho CRM program. I have checked the modules, and the tab is not in there either. I also have checked to see if it was still linked in the Zoho Mail app add-on, and it is logged in. I have deactivated, re-activated, signed out, signed back in, and still no sign of the email tab. Any advice / suggestions to get this problem solved would be great.
