You can choose between the following licensing models for Office 365 and related components.
Server-based Licensing: In the server-based approach, every Office 365 component you manage in eG Enterprise, regardless of its type, consumes a Premium Monitor license in eG Enterprise. This means that you can manage as many components as your license permits.
User-based Licensing: In the user-based model, you can monitor any number of components of type Microsoft Office 365, Microsoft Exchange Online, Microsoft SharePoint Online, Microsoft Yammer, Microsoft OneDrive for Business, Microsoft Skype for Business Online, Microsoft Teams, Microsoft Teams - Domain, in your environment without any agent licenses, provided the total number of: unique users who accessed any of the managed components of the above-mentioned types over the last 90 day period does not exceed the licensed number of Office 365 Users.
Every day, eG Enterprise computes the total count of unique users and stores this count in the eG backend. The solution then checks the values so stored in the last 14 days for violations. When performing this check, if the solution finds that the total number of unique users on any day during the last 14 days exceeds the licensed number of Office 365 Users, then a license violation is registered.
If this license is violated in any 7 out of the last 14 days, the eG agents will stop monitoring any of the managed Office 365 components.
Moreover, after the seventh violation (in 14 days), you will not be able to add/manage any additional Office 365 component (of the types mentioned previously). For every license violation that occurs in the last 14 days, eG sends mail alerts to the configured eG administrator mail ID regarding the license violation.
Every Exchange Online Tenant, O365 Mail Sender, and O365 Mail Receiver component you add will consume a Premium Monitor License each. User-based licensing cannot be applied to these components.
