Before you add those seven people to a new chat, read this. It will take two minutes and might save your team months of confusion.
A project kicks off. You add the right people to a new chat. Decisions get made, files get shared, context builds up. Everything looks fine — until it isn't.
With a 10-person team and no shared channel, you end up with a web of overlapping group chats — each with a different combination of members. The same question gets asked in four different places. The same file gets shared three different times. Nobody has the full picture.
This is what fragmented knowledge looks like. Each chat is a silo. Decisions made in one are invisible to everyone in another. Files go missing. Context gets repeated — or lost entirely.
Each problem below feels small in isolation. Together they compound into a team that spends more time re-explaining the past than building the future.
Only the people in the chat can see what was decided, said, or shared. Everyone else is excluded by default.
With 10 team members you could easily have 15 group chats — AL+BK, AL+BK+CR, BK+CR+DM, and so on. Nobody has the full picture.
Adding someone to a group chat gives them no history in many platforms. They start from scratch with zero context.
Documents shared in chats are buried and expire. Version confusion sets in. Nobody knows what the latest version is.
Because the answer is locked in a chat nobody else can see, everyone asks it again and again. And again.
When someone leaves the organisation, their contributions in private chats can become inaccessible. Gone forever.
A channel is a persistent, searchable, inclusive workspace. Everything posted there is the team's collective memory — not a private conversation that expires when someone scrolls too far.
Any message, file, or decision from day one is one search away. The team's knowledge compounds over time instead of evaporating.
Meetings held in a channel automatically store transcripts, recordings and summaries right there — so anyone can catch up without asking.
Important decisions, briefs, and links can be pinned to the top of a channel. New joiners find them immediately.
Every file shared in a channel goes to a shared library — searchable, versioned, and accessible to everyone on the team.
Replies live inside threads, so the main channel stays readable and decisions are grouped with the conversations that created them.
Anyone in your organisation can discover and join open channels. Need confidentiality? Private channels exist for exactly that.
Worried channels will feel stiff or formal? They won't. Channel posts support threaded replies that work exactly like the inline replies you already use in group chats — same experience, dramatically better outcomes.
Every threaded conversation is preserved in context, searchable by the whole team,
and readable by anyone who joins later. You get the intimacy of a focused chat
and the permanence of a shared record — simultaneously.

Channels don't just benefit your colleagues. They build a living, structured knowledge base that AI agents, automations, and Copilot can tap into — right now, today. This is the capability your team has been waiting for. You can't get it from group chats.
Copilot reads your channels and can instantly summarise what happened, what was decided, what's outstanding — and answer questions as if it attended every meeting.
Build agents that draw on your channel history, pinned files, and SharePoint docs to answer questions, onboard new starters, or act as an always-on project expert — all grounded in your team's real knowledge.
A message in a channel can trigger a workflow — create a task in Planner, update a record in Dataverse, send an approval request, or post a summary to another team. Instantly.
Meeting transcripts stored in a channel become raw material for AI — summarised, actioned, and cross-referenced against previous discussions. Every meeting compounds your team's knowledge.
Ask "What did we decide about the Q3 budget?" and get an answer with citations. Channels give AI the structured, persistent data it needs to be genuinely useful — not just a chatbot.
Connect a Power Platform Dataverse to your Team and it becomes a playground for agents, flows and automations — all grounded in the conversations and data your team already produces in channels.
You don't need a big rollout. Start with your next project and do it right from the beginning.
Search for an existing Team first — there probably already is one. If not, create one. A Team is the container, a shared workspace. If a group of people work together regularly, they probably deserve their own Team.
Channels within a Team keep conversations organised. Use General for team-wide updates, then create a channel per project: Project Phoenix, Budget 2026, etc.
When you have a project update, a question, or a file to share — post it in the channel. Resist the urge to "just send a quick message" in a private chat instead.
Click "Reply" on any channel message to open a thread. It works exactly like the inline replies you already use in group chats — same muscle memory, same experience, but permanently searchable and open to the whole team.
Schedule meetings from within a channel so recordings and transcripts are automatically stored there. Your meeting history becomes part of the project record.
The hardest part is getting everyone on board. Send this link the next time someone creates a group chat that should have been a channel.
