Track agent performance in shared mailboxes without the “send on behalf of” permission
send on behalf of
permission is enabled.
If you’d like to get agent performance metrics without turning on the Send on Behalf setting, the only alternative is enabling Audit Logging for your mailboxes, and giving access to Email Meter to those logs to capture that information.
Why do I need to install an extra application?
How can I know if my Microsoft 365 subscription supports audit logs?
Isn't there other alternative to get these metrics?
