We are on Zoho CRM Standard Edition and wanting to use the Microsoft Outlook plugin.

I was able to download the plugin. Upon trying to login to plugin from outlook, it gives the following message in the pop-up. I went looking for subscription add-ons where I can add this plugin but could not find it under my subscription link. Can you please indicate where do I go to purchase the add-on. We are not looking to upgrade our editions to Professional as we are only looking for this incremental functionality.

Thanks for your help.
