Most Microsoft 365 tenancies were born from a licence purchase: someone needed email, someone bought Business Standard, and the tenancy grew from there. Five years later there are three global admins nobody remembers appointing, MFA is "planned", and every departed employee's mailbox still syncs somewhere. M365 done well starts from the opposite end: identity first, licences second.
The baseline before anything moves
Before the first mailbox migrates we set: MFA enforced for everyone (no exceptions for the boss — attackers know bosses opt out), named break-glass admin accounts stored offline, conditional access sketching where sign-ins may come from, and mail protection tuned beyond defaults. This takes a day and prevents most of the incidents that make M365 look insecure. It never gets retrofitted once the business is busy inside the tenancy — which is why it must happen first.
Licence right-sizing is an annual habit
Microsoft's SKU maze rewards review: the mix of Business Basic, Standard and Premium that fit last year rarely fits this year, and unused licences renew silently. An annual audit typically pays for itself; CSP pricing through our PrinterBullet platform keeps the commercial side itemised and renewals tracked.
Microsoft protects the service, you protect the data
The shared-responsibility line surprises people: Microsoft keeps Exchange Online running; it does not promise to recover the mailbox a leaver purged or the SharePoint library ransomware rewrote via a synced client. Third-party M365 backup — small, boring, automated — closes that gap and belongs in every tenancy that would miss its mail.
When to stay simple
A three-person firm with no compliance exposure does not need conditional-access engineering — MFA, sensible admins and backup covers it. The design effort scales with what a compromised tenancy would cost you.
