What we operate

Day-to-day administration, end-to-end.

Nine disciplines, one team behind all of them. We take your tenant in whatever state we find it, close the gaps that matter, and keep it running without surprises landing in your inbox.

Tenant configuration

Subscriptions, domains, organization-level settings and the tenant-wide policies that need to line up with whatever compliance regime you sit under.

User lifecycle

The full joiner, mover and leaver cycle: accounts provisioned, licenses assigned, group membership set, and departures closed out cleanly rather than left half-done.

Identity & MFA

Conditional access, policies driven by sign-in risk, MFA enforced properly, and privileged identity management with break-glass accounts tested rather than assumed.

Security baselines

Defender for Office 365 across anti-phishing, attachment sandboxing and URL detonation. Thresholds are tuned to produce signal somebody will act on rather than volume nobody reads.

License optimization

We audit which licenses are going unused, right-size the mix of tiers, and find the savings without stripping features from the people who actually rely on them.

Compliance & audit

Retention policies, eDiscovery, audit log review, DLP rules, and USA data residency configuration where required.

Reporting & analytics

A monthly tenant health report covering login analytics, license usage trends and any security incidents, written to be understood by your leadership team in about five minutes.

Migration & co-existence

Moving off Google Workspace, off an Exchange server in your building, or off an older Microsoft 365 tenant. Hybrid co-existence keeps both sides working through cutover, and mailbox migrations run outside working hours.

Backup & recovery

Independent third-party backup covering mailboxes, OneDrive, SharePoint and Teams, with restore down to individual items. The backups are verified every week, which is a different thing from being scheduled every week.

Why GR IT

What sets our M365 admin team apart.

Four facts about how we operate. Concrete, not aspirational.

Microsoft CSP since 2022

We hold a direct billing relationship with Microsoft, so a licensing escalation travels through partner channels instead of joining the same queue as everybody else.

Tenants under management across the group

Enough tenants under management that patterns become obvious. Whatever is about to break for you, we have almost certainly watched it break somewhere else first.

5-minute P1 SLA, 24/7

Round-the-clock administration from a remote-first senior team. Real engineers responding, not first-line ticket triage.

USA data-residency depth

Tenant provisioning in Microsoft's USA region with compliance documentation for DPL, NYDFS Part 500, and Wall Street requirements.

Industries we work with

Microsoft 365 for the way your sector actually works.

Six industries where we run Microsoft 365 every day. The compliance constraints differ, the DLP rules differ, and the realities of moving people in and out differ. What stays the same is the administration layer sitting underneath all of it.

Real estate

SharePoint carrying the weight of property files, workflow automation behind tenant onboarding, and access built mobile-first for site visits and inspections.

Healthcare

Clinics, hospital systems and physician groups. Patient data separated using sensitivity labels, with retention policies written against HIPAA and the state rules layered on top of it.

Financial services

Asset managers, family offices and fintech businesses. Conditional access shaped around regulated work, and DLP rules written specifically for client communications.

Hospitality

Hotel groups and restaurant operators. Outlook at the front desk handling reservations, SharePoint behind the scenes holding standard operating procedures, and Teams coordinating shifts.

Trading & logistics

Distributors and freight operators running several legal entities across multiple states. Cross-tenant licensing, administration delegated by region, and audit logs separated per entity.

Professional services

Law firms, CPA practices and consulting groups. Information barriers between teams, eDiscovery kept in a ready state, and DLP rules built around client confidentiality.

Self-managed vs managed

What you actually get.

Set side by side, these are the gaps that turn up most consistently when we audit a tenant that has been self-managed for a year or longer.

How it works

A clear engagement model.

The same four stages apply whether we are inheriting a tenant you already run or standing up a new one from scratch.
  1. 1

    Discovery & audit

    1-2 days

    A one-hour audit of the tenant you already have, at no cost. We check MFA coverage, conditional access, how licenses are being used, the Defender baseline and whether DKIM and DMARC actually line up. You end up with a written remediation plan to accept, amend or take elsewhere.

  2. 2

    Remediation

    1 week

    Security baselines go on, MFA gaps get closed, Defender is tuned to your environment and the licensing is tidied up. Everything is communicated before it happens and carried out inside agreed change windows.

  3. 3

    Operations

    Ongoing

    The daily running of the tenant: tickets, change requests, monitoring and a monthly health report. Response is tiered by priority (P1 5min · P2 10min · P3 30min).

  4. 4

    Strategic review

    Quarterly

    We go through tenant health, where compliance stands, what licensing could be optimized further, and what is coming next. It lands as a written summary your leadership can get through in five minutes.

Common questions

Microsoft 365 admin, frequently asked.

You do not. Least-privilege roles are the default, so Exchange Admin, Security Admin, License Admin and similar. Global Admin is used only for one-off elevations inside an agreed change window, and every one of those appears in your monthly report.

Either, and repairing an existing tenant is by far the more common engagement. The free one-hour audit happens first, and the remediation plan that comes out of it names exactly what we would change and in what sequence, before anybody touches anything.

Five minutes on a P1 critical issue. Ten minutes on a P2. Thirty minutes on a standard P3 request. That runs around the clock rather than only during business hours.

The region your tenant sits in makes no difference to how we work, and we operate in all of them. Customers based in the United States default to East US or West US for data residency. Where your compliance position points somewhere else, we will say so during the audit.

That is a normal ending for these engagements. Handover comes with admin runbooks, change-request templates, and a period where we work shoulder to shoulder with your team until they are genuinely comfortable running it themselves.

Seven things: gaps in MFA coverage, a review of your conditional access policies, an audit of how licenses are assigned, a check on the Defender baseline, whether DKIM and DMARC align, basic eDiscovery readiness, and a sweep through recent admin activity logs. What you get back is a written remediation list ordered by risk and by effort.

Rarely. Most of our clients keep an internal team for end-user support and anything needing hands on site. What we take is the administration layer above that: tenant configuration, security policy, license management and escalations into Microsoft. The helpdesk stays theirs and the platform becomes ours.

Service health is monitored continuously rather than checked once somebody complains. When something touches your services, your stakeholders hear from us inside fifteen minutes with the affected workloads named, the expected resolution time Microsoft has given, and any workaround worth using in the meantime. If recovery stalls, we escalate through our CSP partner channel.

Co-management with internal teams and with other providers is routine for us. The delegation model gets agreed at the start, covering which roles each side holds, how change control works and where escalations go. The handover document then states in plain terms what we touch and what we leave alone.
