Tenant drift creates invisible support cost
Most businesses do not notice the cost of Microsoft 365 drift until account access breaks, shared mailboxes stop behaving predictably, or compliance questions expose how loosely the tenant has been managed.
That is why Microsoft 365 administration should be treated as an operating function, not a set-and-forget license purchase. Ownership, permissions, naming standards, retention choices, and user lifecycle handling all affect how supportable the environment stays.
This is a strong recurring MSP service lane
For MSPs, Microsoft 365 cleanup is both practical and strategic. It resolves immediate friction for users while opening the door to broader identity, endpoint, and security improvements.
The client outcome is simple: fewer access surprises, clearer ownership, and a collaboration platform that does not feel fragile every time a staff change happens.
