Hi

I cannot find any reference for Graph API on getting mailbox statistics for a single mailbox in the same way we do it in Powershell with get-mailboxStatistics.. Do you know anything that could help?

    That is unfortunate. Will carry on using Powershell for this.
    Thank you for this quick reply.

    The Graph API currently does not support any Exchange admin operations, so there is no such endpoint. Use PowerShell, or if you need a Graph-based solution, use the reports endpoint as a workaround (mailbox usage report: https://learn.microsoft.com/en-us/graph/api/resources/mailbox-usage-reports?view=graph-rest-1.0)
