In plain English
Power Automate lets you build “when this happens, do that” workflows without writing code. A flow might save email attachments to a SharePoint folder, post in a Teams channel when a form is submitted, or send an approval request to a manager when a new invoice arrives. Each step uses a connector: a ready-made link to an app such as Outlook, SharePoint, Excel or Teams.
Microsoft 365 business plans let users build and run cloud flows with standard connectors, which cover the Microsoft 365 apps and plenty of others. A paid Power Automate Premium licence adds premium and custom connectors, which many other business systems need, links to software on your own servers, and desktop automation (driving older programs by mimicking mouse and keyboard) run from cloud flows or shared with colleagues. Licences for a single flow are available too. The details change, so check before you build.
When it’s the right tool, and when it isn’t
It’s a good fit when the work happens mostly inside Microsoft 365, the steps are predictable, and someone will look after the flows. It’s a poorer fit when only one or two people need a premium connector, or when the hard part is AI reading messy emails and documents, since its built-in AI features run on credits that come with paid licences, not Microsoft 365 alone. Then another tool, or a custom build, can be cheaper and sturdier.
An example from a small business
Take a hypothetical 10-person QS consultancy that keeps project documents in SharePoint. A simple flow, covered by its existing Microsoft 365 plan, watches a shared mailbox, saves each attachment from a client into that client’s project folder and posts a note in the project’s Teams channel. That’s Power Automate at its best. When the firm also wants fee invoices raised in its separate accounts package, it first checks whether that connection is premium and what it would cost.
What to watch out for
- Licensing surprises. Adding one premium step can mean everyone who runs that flow needs a premium licence, or the flow needs its own.
- Flows that depend on one person. Give business-critical flows more than one owner and write down what they do, so they don’t stop when someone leaves.
- Silent failures. Connections can break when passwords or permissions change. Make sure failure alerts reach someone who’ll act on them.
