It’s official. Microsoft is changing prices for many Office 365 and Microsoft 365 business plans, effective July 1, 2026. In several organisations I’ve already seen the news set off rushed internal emails and spreadsheet sessions, usually in places where nobody has looked at licence assignment for months. If you want to avoid that kind of last-minute chaos, review your licensing setup, usage and renewal dates now. Your first stop as an admin is the Message Center in the Microsoft 365 admin center, where Microsoft posts the official price change announcements, or your licensing partner. For more detail I also read the licensing posts on news.microsoft.com. They list the affected plans and the official messaging, but never the actual prices.

The Message Center shows what Microsoft has announced for your tenant

According to the current announcement, several Microsoft 365 and Office 365 suites change price on July 1, 2026. The Message Center carries the official word for your tenant, and that matters because not every tenant or contract is affected in the same way. If you’re on an Enterprise Agreement or CSP, go through your contract documents and partner communications for renewal terms and possible price locks. I’ve worked with tenants where a missed renewal window led to sudden costs nobody had planned for. Whether you pay annually or monthly also makes a real difference here.

A proper licence inventory exposes unused and double-assigned seats

If you want to keep costs under control ahead of the Microsoft 365 price changes, start with an honest inventory. Under Microsoft 365 admin center → Billing → Licenses you can see which licences you own and how many are actually assigned. Reports → Usage tells you how they’re really used. That’s usually where you find complete E3 or E5 suites assigned to people who only ever open Teams and Outlook, or add-ons still sitting on accounts that no longer exist. In larger tenants, double assignments and orphaned licences turn up surprisingly often, mostly because offboarding is weak or someone made a manual mistake.

Pro tip: Make a regular review of licence assignment part of your renewal process. Nothing protects you better against unnecessary cost jumps when prices change, and it often pays for itself before the new prices even apply.

These are the checkpoints I recommend:

  • Admin center → Billing → Licenses: Assigned vs. unassigned, inactive user accounts
  • Reports → Usage: Feature adoption for Teams, Exchange, Copilot, SharePoint
  • CSV export and filters to find double or orphaned assignments
  • Internal offboarding processes that remove unused licences promptly

E3, E5 and Business Premium need rightsizing before the renewal

In mixed-licence environments, this Microsoft 365 price change is a good reason to look hard at who really needs E5 rather than E3 or Business Premium. Once I’ve analysed real usage, I often find that the security and compliance add-ons make sense for a fraction of the workforce, not the whole company. For comparing plan features, the Microsoft documentation on subscriptions and licences is useful. In many tenants a careful review turns up enough unused or misassigned licences to absorb the increase and still bring total costs down.

For a quick overview of multi-assigned or orphaned licences, you can use the Microsoft Graph PowerShell module (PowerShell 7, at least Directory.Read.All):

Get-MgUser -All | Select-Object DisplayName,UserPrincipalName,@{n='AssignedLicenses';e={$_.AssignedLicenses.Count}}

The output is a simple list you can act on straight away. For deeper analysis, use the admin center reports and the activity reports. The earlier you start, the easier your renewal negotiations will be.

Your renewal date and billing model decide when to act

With Microsoft 365 price changes, timing matters more than anything else. If your renewal falls before July 1, you may be able to lock in current pricing, but always confirm that with your partner or licensing reseller. Monthly billing gives you more flexibility, though since April 2025 you pay a premium for it (I covered this in Microsoft 365 monthly billing: 5% premium from April 2025). Whenever you plan a larger licensing change, take your renewal window into account and ask your partner when the best moment to act is. Sometimes renewing early is the better choice and sometimes waiting pays off, because contracts and local rules vary.

To keep decisions structured, I often sketch the chain from announcement to the final licence change. This Mermaid flowchart shows a typical admin decision path:

Proactive planning beats reactive firefighting every time

Microsoft 365 price changes can’t be avoided, but surprises can. I tell every team I work with to treat price announcements as the starting point for a thorough review rather than a last-minute scramble. Regular inventories, usage analysis and active contract management keep your costs predictable and make conversations with procurement far more productive. A few hours spent on this now are always better than firefighting in June.
