Office 365 applications are covered by the Mailbox Archive Solution license, which appears in the License Summary Report under the information about Application Users. The software calculates license usage based only on the types of users and components that are included in the license. Certain user actions can increase or decrease license usage in the License Summary Report.
For new CommServe computer installations of 11.19 and later, the software enforces the Mailbox Archive Solution license for the following component types:
Mailboxes protected by the following agents:
Exchange Mailbox (Classic)
Exchange Mailbox (OnePass)
SharePoint Office365 licensed site users
OneDrive for Business user accounts
Caution: If the number of any component types exceeds the purchased quantity by 110%, then the software blocks backup operations for all of the listed component types.
For CommServe computers that upgrade from previous feature releases, the software does not enforce the Mailbox Archive Solution license for these components.
For more information about how Sharepoint O365 users are metered, see Sharepoint O365 in the Usage Calculation.
The following Office 365 components are included in the usage calculation:

If a Microsoft Office 365 user account is deleted or removed, the user's OneDrive files are retained based on the retention settings configured in OneDrive.

To view the retention settings in OneDrive, log on the OneDrive administration center as a global or SharePoint administrator, and then from the left pane, select Storage.
