This is the enterprise story. The Copilot Business default-on change is a separate one, I posted on that last week. I'll be unpicking each of these properly over the next few weeks, starting with a map of what Copilot actually is now.

Food for thought 🤔 🔹 Copilot deciding when you pay extra is convenient right up until the invoice. Who set the router's budget? 🔹 "Start on credits, move into the licence later" is now written down. Early adopters fund the bundle. 🔹 An agent with its own identity is a new kind of account.

The switch you used to flick was the thing that started the bill. 🔹 If your spending policy has "auto-apply new services" on (it's the default), every new metered thing Microsoft ships lands in it without anyone touching the policy.

🔹 Code looks like App Builder reframed: dashboards and small line of business apps. Building them costs credits, and running them will too. 🔹 Scout is now Autopilot. Cloud-hosted, its own identity, its own memory, consumption based. Less "my Copilot got a memory", more "I've hired a colleague".

🔹 Two terms to learn. USL is the user subscription licence, the M365 Copilot seat and everything in it. UBB is usage-based billing, credits and pay-as-you-go. Microsoft have now written that split down as the model, so it isn't going away.

🔹 Chat and Cowork are merging, and Copilot will decide which one runs your request. Chat is in the seat, Cowork is on the meter.

6/ What to do: 🔹 Find the flex routing MC post in your tenant's Message Center 🔹 Admin Center > Copilot > Settings > Flexible inferencing during peak load periods 🔹 PPAC has a separate toggle for Dynamics 365, Power Platform, Copilot Studio 🔹 Not visible if you've bought Multi-Geo

4/ Context: When Copilot joined the EU Data Boundary commitment in March 2024, the message was "EU traffic stays within the EU Data Boundary." Flex routing is the release valve, it lets MS satisfy demand from datacenter regions around the world as needed.

5/ Data at rest still stays in the boundary. Data is encrypted in transit. But if flex routing is on, prompts and responses may traverse to the US/Canada/Australia during peak load.

2/ Microsoft is introducing "flex routing", a setting that lets EU/EFTA tenants use Copilot LLMs outside of their sovereign data boundary (i.e. in USA, Canada etc.) when they are having peak demand issues.

3/ The default state is per-tenant: 🔹 New tenants (post-25 March 2026): on by default 🔹 Existing tenants: individual MC posts communicate your tenant's default Mine (MC1269219) shows off by default, live from 17 April 2026. Yours could differ.

🧵 1/ Granular toggle for enabling Anthropic AI in Copilot coming soon. MC1263276, rolling out late April 2026. If you run Copilot or manage anyone who does, this one matters.

6/ From late April you can scope it. Specific users, Entra ID groups, up to 999, nested groups supported. Enforced across Admin Center, PPAC, and Copilot Studio.

4/ Excluded from the EU Data Boundary. Excluded from in-country commitments for the UK, Australia, India, Japan etc. EU/EFTA and UK tenants have it off by default for exactly this reason.

5/ Until now you had to choose: accept that for every user in the tenant, or turn Anthropic off and lose the features entirely. Not exactly a fun conversation with a compliance team.

2/ TL;DR: Admins will soon be able to assign Anthropic (Claude) access in M365 Copilot to specific users or Entra ID groups. No more all-or-nothing tenant toggle.

3/ Why it matters: Claude powers some of Copilot's best stuff — Researcher, Agent Mode in Excel, Office agents, Copilot Studio. But processing happens outside Microsoft's data boundary.

Microsoft has ~15 retirements and service changes on the 2026 roadmap. A lot of coverage frames this as chaos. But there's a why behind it. 🧵

This isn't random churn. It's a security strategy playing out over years. Doesn't remove the pain. Migrations are still work. But remembering the why does shift how you look at 2026.

Any of these deprecations eating into your planning time? Or are you now worrying about which changes you've missed entirely... 😅

At least one ties directly to the Secure Future Initiative. The security overhaul Microsoft kicked off after those high-profile breaches. It's been running quietly in the background. Timelines fit for changes to show up in production now.

Evergreen platform means standards evolve. MS has too much history maintaining legacy stances, so it's good to see movement here. That said, some changes are still unfathomable without knowing the goal. Other than Copilot everywhere. 😄

Microsoft has announced a significant change to what’s covered by Teams Premium, landing 1 April 2026. It impacts both Places and large-scale events, and it’s worth a look if Places felt too expensive before or if you bought Premium mainly for events. 🧵⬇️

📍 Places changes follow the same pattern Core end-user features move into base M365 (E3/E5/Business): • Places Finder • Places Explorer • Desk booking No extra cost if you already have E3/E5. Places is no longer positioned as Premium-adjacent by default.

🏢 Shared Device → Shared Space • One licence now covers up to 4 desks/spaces • Space analytics & booking policies included Teams Premium is left more tightly focused on meetings, calling and intelligence. Details still to come, but the direction is clear: techcommunity.microsoft.com/blog/microso...

Big picture: Teams Premium has long been a catch-all for “advanced” Teams features. These changes narrow that scope. The licensing gate is shifting from who has Premium to what you need to do at scale. Events are the clearest example.

🎥 Events & webinars Many features that previously required Teams Premium move into Teams Enterprise at no extra cost, including chat, reactions, engagement insights, branding and eCDN. Capacity is now licensed via Attendee Packs
