ManageEngine M365 Manager Plus vs OpenMetadata

M365 Manager Plus handles reporting, management, and automation for Microsoft 365 tenants from an on-premises install, shipping numbered builds that share a train with its sibling M365 Security Plus — the two carry overlapping notes at the same build numbers. Recent builds mix genuine administrative additions with security work: shared, guest, and resource mailboxes now count as free across all modules, group memberships can be assigned from template rules, and mailbox management actions became available inside automation policies. Builds 4817 and 4818 fixed a predictable-SSO-ticket CVE, a privilege escalation in delegated technician administration, and remote code execution via PowerShell embedded in CSV input.

The product's direction is administrative depth rather than new surface — more reports, more attributes exposed to bulk operations, more management tasks reachable from automation policies rather than clicked one at a time. That is the right axis for the buyer, who is a tenant administrator doing the same operation across thousands of objects. Running underneath it is a security-hardening pass that has surfaced three distinct classes of flaw in two builds, all of them in the delegation and integration machinery that lets one console administer a whole estate.

Automation policies have absorbed mailbox tasks and template rules now drive group membership, so the next candidates are the remaining manual bulk operations — license assignment and user lifecycle actions are the ones the reports keep pointing at.
