Microsoft 365 Management & Licensing
Microsoft sends the invoice either way. The difference is whether someone is matching licenses to actual people, turning on the security you’re already paying for, and revoking access the minute an employee walks out the door.
Pinnacle IT’s cloud team manages Microsoft 365 tenants as a discipline: user lifecycle, licensing, security configuration, and the administrative work — mailboxes, Teams, SharePoint — that quietly determines whether the platform helps your people or frustrates them.
Onboarding and offboarding: where tenants prove themselves
Day one: ready to work
Account created, licenses assigned, device enrolled and configured, group memberships and shared mailboxes in place, all before the new hire sits down. First impressions of your organization include your IT.
Departure day: access ends at a fixed minute
Same-day offboarding: sign-out forced across every session, credentials disabled, mailbox and files preserved and delegated, licenses reclaimed. For sensitive departures, we coordinate with HR and legal so access is revoked at an agreed time, devices are collected, and evidence stays intact.
This is the single most common gap we find in tenant reviews: departed employees with active accounts, weeks or months later. Every one is an open door with your company’s name on it.
License optimization: stop funding ghosts
Nearly every tenant we review is overpaying. The usual suspects:
- Paid licenses still assigned to employees who left last fiscal year
- Premium tiers for users who need basic ones — and basic tiers for users whose missing security features cost more than the upgrade would
- Two or three overlapping products (backup, email filtering, storage) purchased at different times, each auto-renewing
- Add-ons nobody remembers buying, attached to nobody’s stated need
We map every subscription to a person, a department, and a need, then audit the mapping quarterly against headcount. Your per-user cost becomes a published number your finance team can budget against, and renewals stop arriving as surprises.
The security you already own, turned on
Microsoft 365 Business Premium, our recommended baseline for most organizations, bundles a serious security stack: Defender, Intune device management, Entra ID conditional access. In most tenants we take over, much of it has never been enabled. You’ve been paying for MFA enforcement, device compliance, and threat protection the whole time; it just wasn’t configured.
Turning on what you own is often the highest-value security work we do — and it’s frequently what makes the difference on a cyber insurance questionnaire.

Whose job is protecting your Microsoft 365 data?
Microsoft is explicit about this. Under its shared responsibility model, the customer always retains responsibility for their data, their user accounts, their access management, and their devices across every cloud service, including Microsoft 365. Microsoft keeps the service running; keeping your data recoverable when it’s deleted, encrypted by ransomware, or sabotaged by a departing employee is your job.
We close that gap with SaaS backup for mail, OneDrive, SharePoint, and Teams. Retention you control, restores we actually test.

Day-to-day tenant administration, handled
- Mailbox, Teams, and SharePoint administration — permissions, shared resources, retention
- Security and compliance configuration reviews on an ongoing basis, not once at setup
- User moves, adds, and changes with agreed lead times, tracked in our service system
- GCC and government licensing guidance for public-sector organizations — including an honest answer when compliance doesn’t require the expensive tier
- Vendor liaison with Microsoft — we hold the escalation, you keep working
What we look for in a tenant review
- Active accounts and assigned licenses for departed employees
- MFA and conditional access coverage — enforced, not just available
- Global administrator counts (the right number is small, and it isn’t “whoever asked”)
- Paid-for security features sitting disabled
- External sharing settings letting data travel further than anyone intended
- Backup posture for mail, files, and Teams — and whether a restore has ever been tested
- License tiers versus actual usage, mapped to a per-user monthly cost
When did someone last audit your tenant?
Request a Microsoft 365 tenant review — we’ll map your licenses to your people, your settings to your risks, and show you exactly what you’re paying for that you don’t need, and what you own that you aren’t using.
Microsoft 365 Management FAQs
How much can license optimization actually save?
It depends on how long the tenant has drifted, but reclaiming departed-employee licenses, collapsing overlapping products, and right-sizing tiers routinely recovers a meaningful share of monthly spend. Just as often, the bigger value runs the other way: discovering you already own security capabilities you were about to buy separately.
How fast is onboarding and offboarding, really?
Same-day, with agreed lead times for standard requests. Offboarding can be executed at a fixed minute you choose — access revoked, sessions killed, mailbox preserved — which matters most exactly when the departure is sensitive.
What Microsoft 365 license should our organization be on?
For most organizations of 20–300 users, Business Premium is the right baseline: the cheaper tiers strip out the security stack (Defender, Intune, conditional access) that you’d then buy separately for more. Government organizations may need GCC variants — we’ll tell you when compliance requires it and when it doesn’t.
Can you manage a tenant our previous provider set up?
Yes, that’s most of them. A takeover starts with the tenant review: we document what exists, fix what’s risky, and give you the first accurate picture of your licensing and configuration many organizations have ever had.
Does Microsoft back up our data?
Microsoft provides service uptime and limited recovery windows, but its own shared responsibility model places data protection with you, the customer. Deleted mailboxes, ransomware-encrypted files, and malicious insider deletions are your responsibility to recover from which is what third-party SaaS backup with tested restores is for.
