Microsoft 365 Copilot has had a fast first half of 2026, and the headline release worth knowing about is Copilot Cowork, which went generally available to all Microsoft 365 Copilot customers on 1 May 2026. It’s a meaningful shift in what Copilot actually is. For the past eighteen months Copilot has mostly been something you ask questions of — summarise this thread, draft that email, pull these numbers out of a spreadsheet. Cowork moves it from answering to doing: multi-step work delegated across email, Teams, calendar and documents, with you approving each action along the way.
The practical picture is that you can hand Copilot something like “pull together a briefing for tomorrow’s client review, draft the follow-up email and book a half hour with the account team on Thursday” and it will actually work through the steps, surfacing each one for your sign-off rather than burying you in a wall of text. Cowork is available on iOS and Android too, so you can kick off a piece of work from your phone on the way to a meeting and come back to a finished outcome. Alongside it Microsoft is rolling out a Teams-mode Copilot that joins channels and meetings as a shared collaborator, narrated video recaps that replace the old text summaries, and GPT-5.5 Reasoning across Chat, Word, Excel and PowerPoint.
For an SMB owner the question isn’t really whether this is impressive — it plainly is — but what it changes about how you run things. Three things worth thinking about now. First, governance: an assistant that can act on your behalf needs sensible guardrails around what data it can touch, what actions it can take without approval, and how those actions are logged. Second, training: the people who get the most out of Cowork will be the ones who learn to brief it like they’d brief a capable new starter, not the ones who treat it like a search box. Third, what not to delegate yet — anything customer-facing, anything that touches money, anything where a hallucinated detail would be embarrassing or expensive. Approval-per-step helps, but the responsibility still sits with the human.
Done well, this is a genuine productivity lever for small teams. Done badly, it’s a way to make small mistakes faster. If you’d like a walk-through of Cowork against your team’s actual workflows, or help setting up the governance and training scaffolding before you turn it loose, that’s exactly the kind of thing our Microsoft 365 team is here for.
