Microsoft 365 tenant health check: what leadership needs

Written by Orchestry | Nov 10, 2026, 12:30:00 PM

Microsoft's Health dashboard gives you what Microsoft Learn calls "a snapshot of the overall health of your environment": service incidents, license use, app updates and MFA. Workspace growth, inactive sites, missing owners, guests, sharing and storage aren't among its sections; those sit in at least four more admin surfaces.

A Microsoft 365 tenant health check is a regular summary of how your tenant is governed: how fast workspaces are growing, how many are inactive or missing owners, how many guests and sharing links exist, how storage is trending, and where your security posture stands, compared with the last period. The five minutes is the time it takes to read and forward a report that's already been generated on a schedule.

When you need every workspace, owner and sharing link listed, that's a full Microsoft 365 tenant inventory, a different job.

What the Microsoft 365 Health dashboard shows about M365 health status

Microsoft 365 Health dashboard in the admin center showing service health, usage and recommended actions

You open the Health dashboard from the admin center's view dropdown (Simplified view, Dashboard view, Health), signed in with the Global Reader role. Alerts sit at the top: general service incidents and billing problems such as an expired subscription. Below them are your top services' status, daily usage, license utilization, desktop app updates and recommended actions such as turning on MFA.

Service health is one part of that picture. It shows the health state of each Microsoft service with any active incidents and advisories, and its history tab covers issues resolved in the last 7 or 30 days. Planned maintenance doesn't appear there; you'll find it in Message center.

Both pages tell you whether Microsoft 365 is running and being used, a fair answer to part of leadership's question. The governance half, meaning how many workspaces you have, who owns them, who outside the organization has access and what's shared, isn't on either page.

What a Microsoft 365 tenant health check should cover for leadership

Seven numbers make up the governance answer:

  1. Workspace growth by type. Teams, SharePoint sites and Viva Engage communities, so leadership sees whether creation is outpacing cleanup.
  2. Inactive workspaces. The share of workspaces nobody used in the period, and whether it's rising. Based on Orchestry data, 67% of workspaces showed no activity in the previous 90 days when Orchestry first measured them.
  3. Ownership gaps. Workspaces with no owner, or fewer owners than your policy requires.
  4. Guest accounts. How many people outside your organization have access, and which way that count is moving.
  5. Sharing links. How many links people created in the period, especially links anyone can open.
  6. Storage trend. Storage across SharePoint, OneDrive and Exchange, and how fast it's growing.
  7. Security posture. Your Microsoft Secure Score.

Two comparisons make them readable: the change since last period and how you compare with organizations of a similar size.

Where the rest of your M365 health data lives natively

By our count, the governance numbers sit in at least four more admin surfaces: the Microsoft 365 admin center's reports, the Defender portal, the Microsoft Entra admin center and the SharePoint admin center. Each has its own time window and, in places, its own license requirement.

Surface Where What it answers Time window Access or license note
Usage reports Microsoft 365 admin center > Reports > Usage Activity per service, such as SharePoint site usage and Teams team activity 7, 30, 90 or 180 days; data typically 24 to 72 hours behind Names hidden by default until a Global Administrator changes the setting
Adoption Score Microsoft 365 admin center > Reports > Adoption Score How people use Microsoft 365, compared with organizations of a similar size Last 28 days, updated daily Organization level only; not available in GCC, GCC High or DoD
Microsoft Secure Score Microsoft Defender portal Security posture, measured by recommended actions taken Syncs daily Recommendations for supported products you're licensed for
Microsoft Entra recommendations Microsoft Entra admin center > identity overview > Recommendations Identity configuration compared with security best practice Analyzed daily Some recommendations need a P2 or other license
Data access governance and site lifecycle reports SharePoint admin center Sharing activity; site ownership, inactivity and attestation Activity reports: last 28 days; lifecycle reports: each policy run SharePoint Advanced Management: base license plus a Copilot license, the Plan 1 add-on or Microsoft 365 E7; E5 alone gets activity reports for up to 10,000 sites

Lined up, the windows don't match: usage reports run from 7 to 180 days, Adoption Score and the sharing activity reports look back 28 days, and Service health history stops at 30.

Count OneDrive when you count sharing links. Based on Orchestry data, the split is lopsided: 92% of company "Anyone" sharing links were found in OneDrives.

How Microsoft Secure Score fits into a tenant health answer

Microsoft Secure Score measures your security posture, and a higher score means more of Microsoft's recommended actions are in place. Its recommendations cover products including Microsoft Entra ID, Exchange Online, Teams, SharePoint Online and Purview Information Protection, and it already compares your score with similar organizations.

Microsoft is direct about the limit: the score reflects how far you're using security controls that help offset breach risk, and Microsoft says it isn't an absolute measure of how likely a breach is. Put it beside the six governance numbers as the summary's security input.

How to build a Microsoft 365 tenant health report leadership will read

You can build this by hand in any tool, a spreadsheet included.

  1. Pick the seven numbers and keep the set fixed. Outcome: a definition of healthy that doesn't change from month to month.
  2. Set one cadence and one reporting date. Outcome: leadership knows when the answer arrives.
  3. Record last period's figures beside this period's. Outcome: the report shows direction as well as the count.
  4. Add one line of context per number. Say what changed and what you'll do about it. Outcome: leadership reads your plan alongside the figure.
  5. Have someone other than the author review it. Outcome: errors and missing context get caught before it goes out.
  6. Send it to named readers in a format they'll open, such as a PDF or a shared page. Outcome: the five-minute read happens without an admin center login.

By hand, that's a recurring export-and-paste job across four portals, competing with everything else on a lean team's list. Monash Health manages Microsoft 365 for 30,000 users with a core team of only three people, and the Monash Health case study shows how reporting and automation helped that team reduce sprawl.

Orchestry's health checks generate this report on a schedule you set: monthly, quarterly or semi-annually. Each pulls workspace growth by type, sharing links created in the last 180 days, storage across OneDrive, SharePoint and Exchange, Teams engagement and Secure Score into a single report, so steps 1 to 3 happen without exports.

How to read a tenant health report in five minutes

Read the change since last period first, then the benchmarks, then the recommendations. Direction shows whether things are improving, benchmarks show whether the level is typical, and recommendations say what happens next.

Orchestry health check report benchmarking workspace inactivity and guest accounts against similar-size organizations, beside Microsoft Secure Score

Orchestry's health checks show whether your workspace count grew or shrank since the last period. Workspace inactivity and guest accounts are compared with organizations of a similar size, with trend lines since the last period, and Microsoft Secure Score sits beside them with Microsoft's own peer comparison.

Your open Orchestry recommendations follow, sorted by most urgent, so the last thing leadership reads is the to-do list.

With the review process turned on, new reports start in a Ready for Review state, where Orchestry admins and assigned reviewers annotate any section and add custom recommendations for the action items. Those custom recommendations also land on Orchestry's Recommendations page.

Publishing makes the report available to viewers who aren't Orchestry admins, such as your leadership team, and notifies them by email and in Microsoft Teams. It downloads in a PDF-friendly format with your company logo.

How a scheduled M365 health report fits alongside continuous monitoring

A scheduled report is a summary on a fixed date, and problems shouldn't wait for it. Keep alerts and recommendations running between reports, so the report shows what changed and what you already did about it.

Between reports, Orchestry's recommendations scan your environment every night and surface issues such as stale workspaces, guest access and missing owners. When a health check number moves, Orchestry's workspace reporting gives you the list behind it across Teams, SharePoint and Viva Engage, with filterable views and actions you can take from the report.

Leadership gets the five-minute read on a fixed date, and you work the detail underneath it the rest of the month.

"Orchestry has been a set-and-forget solution for us. It's very low touch for IT, but delivers very high value across the University." - Robert Jurgensen, Head of Cloud Infrastructure, University of Waikato

Frequently asked questions about a Microsoft 365 tenant health check

How do I check the health of my Microsoft 365 tenant?

The Health dashboard and Service health in the Microsoft 365 admin center show whether Microsoft 365 is running. For governance, track workspace growth, inactivity, ownership, guests, sharing links, storage and Secure Score against the last period, and report them to leadership on a schedule.

Where is the M365 health dashboard?

It's in the Microsoft 365 admin center. Sign in with the Global Reader role and choose Health from the Simplified view, Dashboard view and Health dropdown. Service health is under Health > Service health.

What's the difference between Microsoft 365 service health and tenant health?

Service health reports on Microsoft's services: each one's health state, active incidents and advisories, and issues resolved in the last 7 or 30 days. Tenant health is how your own tenant is governed: workspace growth, inactivity, ownership, guests, sharing, storage and security posture over time.

Does Microsoft Secure Score measure tenant health?

It measures one part of it. Secure Score reflects how many of Microsoft's recommended security actions you've taken, and Microsoft says it isn't an absolute measure of how likely a breach is. Use it as the security input beside the governance numbers.

How do I automate M365 health reporting?

Natively, you can export usage reports to Excel or Power BI, or pull them through the Microsoft Graph reports API, then build the comparison yourself. Orchestry's health checks generate the report on a monthly, quarterly or semi-annual schedule and notify the viewers you name once it's published.

How often should you run a tenant health check?

Match the cadence to how often leadership reviews IT. Microsoft suggests running data access governance snapshot reports quarterly and activity reports monthly, which makes monthly or quarterly a sensible default.
