A lot of growing businesses are about to learn the hard way that a notification is not the same thing as a workflow.
Microsoft says Office 365 Connectors in Teams will be progressively disabled starting May 18, 2026, with rollout completing by May 22, 2026. After that, the old connector-based webhooks stop working. Microsoft is directing teams to move those notifications into Power Automate-based Workflows.
If that sounds like back-end plumbing, it is. But it is the kind of plumbing that quietly runs real parts of a business.
For a growing company, these old Teams alerts often sit in the middle of work that actually matters. New website leads hit a channel. Service issues trigger a post for the ops team. A purchasing request lands in a manager thread. A job status update drops into Teams so someone knows to call the customer. An estimate gets flagged for approval. A support escalation shows up where the team is already coordinating.
The Real Problem with Chat-Based Habits
When those posts stop showing up, the real problem is not Microsoft changing a feature. The real problem is that a critical business handoff was never designed clearly enough in the first place.
That is the useful lesson here.
If your process depends on someone noticing a message in Teams, remembering what to do next, and manually carrying it into the next step, you do not have an automated workflow. You have a chat-based habit.
That works right up until it doesn't.
Asking Better Questions About Your Workflow
This is why the connector shutdown matters more than it first appears. It forces growing businesses to ask a better question than how to keep the alert alive.
The better question is, "What should happen after this event, and where should that workflow actually live?"
Sometimes the answer is simple. Rebuild the alert in Workflows or Power Automate, point it at the right channel, and move on.
Sometimes that is not enough.
If a website form should create a real intake record, route it to the right team, start a response timer, and surface status back to the team, then a Teams message should probably be the side effect, not the system.
If a service issue needs ownership, due dates, customer context, and escalation rules, then the right fix may be a Microsoft-first workflow built around Teams, SharePoint, Power Automate, or Dynamics. Or it may be a custom internal tool if your process is too specific to keep duct-taping together.
That is where a lot of businesses get stuck. They try to preserve the message instead of fixing the handoff.
The Migration Path to Power Automate
Microsoft's migration path is useful here. The newer Workflows approach can handle incoming webhooks, and Microsoft says these webhook templates do not require a premium license. MessageCard payloads are also supported for migration, though interactive buttons from older cards are not. If your old alert expected people to click a button inside Teams and push the process forward, you may need to redesign that step using Adaptive Cards or a better approval flow.
In plain English: this is a good time to stop copying yesterday's setup and decide whether the workflow itself makes sense.
Three Ways to Sort Your Alerts
For most growing businesses, the right move is not replacing every alert blindly. The right move is to sort your alerts into three buckets:
- Simple FYI notifications that just need a cleaner Teams workflow.
- Operational handoffs that should create or update a record in a real system.
- Messy processes that need a better internal tool, approval flow, or customer-facing workflow altogether.
That exercise usually tells you a lot.
It shows which parts of the business are still running on memory, manual follow-up, and lucky timing. It shows where Microsoft 365 is already a strong backbone. And it shows where another app is not the answer, but a clearer workflow is.
The FlowDevs Approach
That is the FlowDevs view of this kind of change.
Start with the workflow, not the software. Decide what the business event is, who owns the next step, where the record should live, what the team should see, and what should happen automatically. Then choose the right Microsoft-first build around that.
Sometimes that means Power Automate and Teams. Sometimes it means SharePoint, a portal, or a small custom internal system. Sometimes it means fixing the website-to-operations handoff so the message is no longer the work.
The point is not to keep every old notification alive forever.
The point is to give your team time back by making the handoff clear, reliable, and visible.
If your business still runs on "someone saw it in Teams," this week is a pretty good time to fix that. If you need help untangling your old connectors and building intelligent, automated workflows, schedule a consultation with FlowDevs today.
