Microsoft cloud platforms

Microsoft Business Services

Tenant design, Exchange Online, Microsoft Entra ID Premium (Conditional Access, groups, SSPR, app proxy, and related controls), SharePoint and Teams, and Azure foundations.

We migrate mailboxes tenant-to-tenant, tune security policies to Microsoft’s own guidance, and build Microsoft 365 backup and recovery programs with reporting and restore testing you can show an auditor.

Microsoft cloud

365, Entra, SharePoint, Teams, and the Azure underneath

We design and run Microsoft estates so identity, email, files, and meetings stay secure, but still feel natural for people doing real work. Below is how we typically shape an engagement; depth scales to what you actually run today. For backup gaps every tenant should understand, see our Microsoft 365 backup guide; for Entra ID, MFA, and conditional access, read Microsoft 365 security basics. MFA is also one of the eight ACSC controls—see our Essential Eight guide.

Productivity cloud

Microsoft 365 & modern work

Teams, SharePoint, Exchange Online, and OneDrive wired together with sensible defaults so collaboration works and sprawl stays contained.

  • Tenant foundations: domains, DNS, connectors, and hybrid identity where you still run AD
  • Teams & SharePoint information architecture, groups, and guest access you can defend in an audit
  • Office apps, policies, and updates aligned to how your devices are managed

Control plane

Microsoft Entra ID, apps & devices

Single sign-on, app assignments, and device posture so the front door to Microsoft 365 (and everything federated behind it) matches your risk appetite.

  • Enterprise applications, SAML/OIDC setup, and token/session hygiene for SaaS sprawl
  • Device join (Entra join / hybrid) and Intune alignment for compliant-access scenarios
  • Directory hygiene: lifecycle, groups, administrative roles, and break-glass discipline

Platform anchor

Azure where it earns its keep

Lightweight or hybrid patterns: conditional connectivity, supporting infra, and landing-zone discipline when workloads belong in Azure, not for cloud for cloud’s sake.

  • Subscriptions, RBAC, and policy guardrails sized to your footprint
  • Backup, monitoring, and cost visibility on the resources you already pay for
  • Migration and coexistence planning when something is ready to leave a datacentre

Exchange Online

Email is still the spine of most organisations

Consistent, well-delivered email lowers help-desk noise and shrinks the simplest breach path: phishing and business email compromise. We harden and operate Exchange Online with Microsoft’s own edge services in mind: Defender for Office 365 patterns such as safe attachments and safe links, anti‑phishing policies, impersonation controls, and realistic quarantine experience for your staff, not security theatre.

Behind the obvious sits the unglamorous work that keeps delivery trustworthy: SPF, DKIM, and DMARC alignment, outbound connectors, shared mailboxes and delegation done cleanly, transport rules that match your governance, and archiving or retention decisions that survive a finance or HR conversation later.

  • Malware & phishing controls tuned to your sector rather than generic defaults copied from a blog
  • Mailbox governance: litigation hold, retention labels, and audit visibility where your lawyers expect it
  • Migration hygiene: batching, throttling awareness, and coexistence when the cutover is bigger than one weekend
  • Mobile & desktop access patterns that respect MFA and device policies you enforce in Entra

Policy-driven access

Microsoft Entra ID Premium: identity that keeps pace with the business

Microsoft Entra ID Premium (including the tier historically sold as Premium P1, and often bundled with Microsoft 365 E3 or Business Premium) is where advanced identity management stops being a shopping exercise and becomes day-to-day security: fewer sticky-note passwords, less mystery about which SaaS is in use, and access rules that respect location, device, and role rather than just “ON or OFF for the whole company.”

Microsoft Entra licensing (Microsoft Learn)

Capabilities we design, test, and operate with you

  • Conditional Access: policy-based rules that require MFA, tighten session controls, or block access using context such as user, group, application, location, device compliance, or sign-in state, so protection scales with risk instead of one flat rule for everyone.
  • Dynamic groups: membership from directory attributes (for example department or role) so access, app assignments, and even licensing can track real org structure with less manual group churn.
  • Self-Service Password Reset (SSPR): users unlock or reset passwords with verified steps and MFA, cutting routine help-desk load while keeping resets inside your security model.
  • Flexible, group-aware MFA: target verification requirements by app or audience rather than only a single org-wide default, so executives, finance, and factory floors can have proportionate controls.
  • Cloud App Discovery: insight into SaaS use by analysing traffic against a broad app catalogue, surfacing shadow IT and helping you decide what to allow, block, or replace with governed alternatives.
  • Application Proxy: publish selected on-premises web apps through Entra with SSL termination and conditional access, giving remote access without handing every user a full VPN for a single browser line-of-business tool.
  • Sign-in hygiene: pairing Premium features with phasing out weak legacy authentication paths where Microsoft supports it, so attackers cannot skip the policies you just built.

Policy lifecycle

Policies are living documents: named standards, staged rollouts, break-glass accounts, and what-if tooling so a change in CA does not become a surprise outage. We document who approved what, and what to roll back if a partner vendor behaves badly.

Premium P2 when you need identity risk automation

Risk-based Conditional Access (for example sign-in or user risk signals) builds on Microsoft Entra ID Premium P2 / Identity Protection-class capabilities. We help you licence and phase what you use so you are not paying for shelf-ware, or missing automated response when accounts are clearly under attack.

Detailed capability and licensing mapping changes with Microsoft’s product releases; we align designs to current Microsoft Learn guidance so you are not anchoring on a forum post from 2019. Learn more: Microsoft Entra licensing

Tenant transitions

Tenant‑to‑tenant email & identity moves

Mergers, divestitures, re‑brands, or “we finally outgrew the old CSP tenancy” all land in the same place: you need mailboxes, domains, and directory objects to move without silently deleting someone’s history. Microsoft documents supported cross‑tenant mailbox migrationpaths; we pair those with identity cutovers, Teams & SharePoint planning, and realistic stakeholder comms.

What we line up

  • Source and target hygiene: dir sync, duplicate addresses, and licensing gaps before a single batch runs
  • SMTP domain move choreography so inbound mail does not bounce while DNS catches up
  • Coexistence options: who logs in where, and how long parallel tenants stay tolerable
  • Security defaults re-applied in the target: CA, MFA registration policy, and admin role cleanup

What we insist on

  • Written rollback thinking before go-live, not optimism
  • Pilot cohorts that represent executives, delegates, and mobile-heavy users
  • Hold and compliance review so a discovery obligation does not collide with migration tooling
  • Help-desk scripts that match real passwords, MFA prompts, and booking links your people will see

Resilience

Microsoft 365 backup, reporting & recovery rehearsal

Microsoft’s cloud engineering focuses on service availability and durability; customer scenarios like accidental admin deletion, broad malicious encryption, or app‑layer corruption still need a protect‑and‑recover strategy you own. This is the familiar shared responsibility picture for SaaS. We help you choose and run tooling that matches your retention story, regulator questions, and insurer questionnaires rather than a generic SKU picked from a price list.

Layer 3 emphasises evidence: scheduled backup reports, periodic restore tests (sample mailboxes, sites, or OneDrive paths depending on scope), and tabletop drills so executives know what “good” recovery looks like before boards are asking awkward questions.

Microsoft’s own portfolio is moving fast

Offerings such as Microsoft 365 Backup continue to evolve on Microsoft Learn. We stay vendor-current on what Microsoft native backup can do versus what still belongs with a specialist ISV; then document the decision in your language so finance and IT agree what “protected” means.

Track record

Two decades with Microsoft business platforms

Layer 3 has lived through the product renames, the on‑prem to hybrid to cloud shifts, and the day‑two reality that licences are easier to buy than to operate well. From Windows Small Business Server-era footprints through modern Microsoft 365, Entra ID, and Azure, we bring pattern recognition, not just the latest admin centre screenshot.

Frequently asked questions

What are Microsoft 365 services?
Microsoft 365 is Microsoft’s cloud productivity suite for organisations: hosted email and calendars (Exchange Online), chat and meetings (Teams), files and intranets (OneDrive and SharePoint), desktop and mobile Office apps, and Microsoft Entra ID for identity and sign-in, typically bought as per-user subscriptions your business manages in a tenant.
Is Microsoft 365 a cloud service?
Yes. Microsoft hosts the services in its datacentres (with regional residency options where available); your data and configuration live in your tenant, accessed over the internet with modern authentication and policies you control rather than running Exchange or file servers only on your own hardware.
Is Microsoft 365 Software as a Service (SaaS)?
In practice, yes: Microsoft 365 is sold and operated as a SaaS productivity suite: you subscribe per user, Microsoft runs the service, and you configure identity, security, and compliance to match your organisation. Some related pieces (such as hybrid identity or Azure resources) sit alongside that model; we help you keep the picture simple for boards and auditors.
Which cloud service is provided by Microsoft Office 365?
“Office 365” was the earlier name for what is now Microsoft 365. The offering is a cloud productivity and collaboration service: email, files, Teams, identity, and Office apps as a subscription, not a one-off boxed product install tied to a single PC.
Does Microsoft 365 have a fax service?
There is no built-in traditional fax machine or PSTN fax line in Microsoft 365 itself. Organisations usually pair Exchange Online with a third-party fax or e-fax provider (or telephony platforms) if they still need fax workflows. If you are modernising comms, see our business VoIP and hosted PBX services or we can map options that meet compliance without bolting on fragile one-offs.
What is Microsoft Dynamics 365 Customer Service?
Dynamics 365 Customer Service is part of Microsoft’s Dynamics 365 line: think customer engagement, case management, and contact-centre style capabilities. That is not the same SKU family as core Microsoft 365 E3 or Business Premium. Many enterprises run both; licensing and integration paths deserve a deliberate plan. Talk to us if you are unsure what you already own or what should plug into what.
We already have Microsoft 365 E3 or Business Premium. Doesn’t Entra Premium come with the tenant?
Often, yes: suites such as Microsoft 365 E3 and Business Premium bundle Microsoft Entra ID Premium capabilities (the tier many people still call “Premium P1”) so you are licensing identity features, though turning them on is another step. We focus on which controls actually ship value for your risk: Conditional Access, groups, SSPR, app publishing, and discovery, documented so finance, IT, and auditors share one story.
Can you move all our mailboxes to a new tenant without weeks of drama?
Microsoft supports structured cross-tenant mailbox migration scenarios; we plan batches, coexistence, domain moves, and cutover comms so email keeps flowing while identities and workloads shift. Scope and timelines depend on size, compliance holds, and third-party systems; we map that honestly before anyone commits.
Doesn’t Microsoft already back up Microsoft 365?
Microsoft engineering provides service availability and resiliency for the cloud; customers remain responsible for scenarios such as accidental deletion, application‑layer issues, and certain security events. Microsoft publishes this as a shared responsibility for cloud services. We design a backup and rehearsal rhythm (often Microsoft 365 Backup, partner ISVs, or both, depending on your compliance story) with reporting and restore tests so recovery is evidenced, not assumed.
Which cloud service model is used by Microsoft Office 365?
Core Microsoft 365 workloads (mail, Teams, SharePoint, OneDrive) are delivered as SaaS. Identity features in Entra ID are often described as IDaaS, and many organisations also use Azure PaaS/IaaS alongside M365 for apps or integration. If you are documenting architecture for security or procurement, we can help you describe the split accurately. Contact us for a plain-language diagram.
How does Microsoft 365 integrate with other Microsoft services?
Under one tenant (and sensible governance), Microsoft 365 shares Entra ID identities with services such as Dynamics 365, Power Platform, and Azure; data moves through supported APIs, connectors, and sometimes hybrid networking. Integration is powerful but easy to over-expose: guest access, service principals, and retention all need owners. We can review your integrations safely.
How does Intune integrate with other Microsoft 365 services?
Microsoft Intune (often discussed with Endpoint Manager) manages device compliance and app protection; Conditional Access in Entra ID can require a managed or healthy device before Outlook, Teams, or SharePoint data opens on a laptop or phone. That tight coupling is how “cloud productivity” and “device trust” stay aligned. Tuning policies without locking out execs is part of the craft. ask us for a staged rollout.
How do I check Microsoft 365 service health?
Administrators use the Microsoft 365 admin centre (Service health and Message centre) to see active incidents, planned work, and advisories for your tenant. That tells you if a widespread outage is real versus a local DNS, identity, or network issue on your side. If dashboards say “healthy” but your people still cannot sign in, you need triage across identity, networking, and client state. Layer 3 can help isolate it quickly.
I can’t access Microsoft 365 services. What should I do?
Start with basics: confirm the organisation is not in a tenant-wide outage (admin service health), try another app or browser, and verify MFA or Conditional Access is not blocking legacy clients. Account lockout, expired password, licence removal, and corrupted profile are all common. If the pattern affects many users or privileged admins, treat it as an incident. We support Australian organisations remotely and on-site to get you unstuck and close the gap so it does not repeat.
How do I disconnect a service from Microsoft 365?
“Disconnecting” might mean revoking a third-party app’s consent, removing an enterprise application integration, or turning off a mail or directory sync connector. Each path lives in a different admin blade and can break sign-in or mail flow if rushed. Document what the integration did, who owns the downstream system, and plan a rollback. Engage us before cutover if production mail or SSO depends on it.
