How does this affect commvault licensing for Mailboxes?  For example (numbers purely made up for ease of explanation) if we have 500 user mailboxes and 500 teams and 500 Outlook Groups used as Distribution lists do we need 1500 mailboxe licenses or just 500 for each user accessing those resources?

Hi @goomba !  I moved your question to its own thread for better tracking.

When in doubt, check the Licensing guide, though I have the section copied below to address your question:

Commvault Backup & Recovery for Mail and Cloud User Applications

Licenses will be counted based on a mapping of user accounts in the associated LDAP directory, or directory of the application that dictates access to the application. In the case of direct mailbox ingestion, only the accounts that have been selected (through manual configuration or auto-discovery) for backup/archive will be counted. User Accounts that have been excluded through configuration will also be excluded from any license consumption in this scenario.

Each unique User / Application combination will be counted as a discrete user. For example, may have their Office 365 Data Protected, as well as their data protected. In this scenario, two user entitlements would be counted, as there are two unique user / application combinations.

In your case, all of your examples are Office 365 apps, so 1 license per user is all you need.
