Chat Best Practices

Mentions, reactions, formatting and urgency flags — small habits that make your messages land.

What you'll learn

  • Use @mentions and reactions without annoying people
  • Format messages so they're easy to read
  • Flag urgency and reply in threads correctly

Most friction in Teams chat is not about the tool — it is about habits. A wall-of-text message with no formatting, an @mention that pings the whole channel for nothing, or a reply buried in the wrong place all make people quietly dread their notifications. The fixes are tiny and quick to learn. Master a handful of them and your messages become the ones colleagues actually read and act on.

Format so it can be skimmed

People read chat at a glance, so help them. Press Shift+Enter to add a line break instead of sending a half-finished thought, and break longer messages into short paragraphs or bullet points. Bold the one thing that matters — a deadline, a decision, a name. Teams has a little formatting toolbar (the “A” with a pen) where you can add bullets, numbered lists, and headings for anything longer than a sentence or two. A message that takes you ten extra seconds to format saves every reader far more.

@Mentions: aim before you fire

An @mention types a person’s name and sends them a direct notification. It is how you say “this part is for you.” Used well, it is precise. Used carelessly, it is noise. Mention the specific person who needs to act rather than @mentioning the whole team out of habit. Most teams treat @team or @channel (which pings everyone) as a “break glass in emergency” tool — fine for a genuine all-hands heads-up, irritating for a routine question. If you only need one person’s eyes, name only that person.

Match the signal to the need: a quiet reaction, a targeted mention, or a rare urgent flag.

Reactions cut the clutter

A reaction — a thumbs-up, a heart, a checkmark — lets you respond without adding a message. When someone shares an update and you just want to say “got it,” react instead of typing “thanks,” which would notify everyone again. Reactions are also a quiet way to vote or acknowledge: a thumbs-up on “Shall we move the meeting to 3?” answers the question without ten near-identical replies.

Priority and urgent messages

For one-to-one and group chats, Teams lets you mark a message as Important (it gets an exclamation flag) or Urgent. An Urgent message is special: it repeatedly notifies the recipient every few minutes until they read it, for about twenty minutes. That is powerful and easy to overuse — reserve it for things that genuinely cannot wait, like “the client demo is breaking right now.” Cry urgent over a routine question and people learn to ignore your flags entirely.

Rule of thumb: before you @mention or mark urgent, ask “does this person need to act, or just be aware?” Awareness gets a reaction or a plain post; action gets a targeted mention; emergencies — and only emergencies — get urgent.

Replying in the right place

In channels, Teams keeps conversations as threads — replies attach beneath the original post. Always reply inside the relevant thread rather than starting a brand-new post, or the conversation fragments and nobody can follow it. Starting a new post should signal a genuinely new topic. In the newer Teams, channel chat feels more fluid, but the principle holds: keep one conversation in one place.

Spot it: the right signal to send

Read each situation and decide for yourself, then tap a card to flip it and check your answer.

Sort the chat moves

Drag each statement into the bucket it belongs to — or tap an item, then tap a bucket. Hit Check placement when you’re done.

Keep threads tightReply in place

Tip: drag with a mouse, or tap an item then tap a bucket on touch screens. Get one wrong and the answer key appears.

How to use it

Write the way you would want to receive it. Lead with the point, bold the deadline, and break long messages into bullets. @mention the one person who owns the next step, not the whole room. Use a reaction whenever a word would do. Save Urgent for actual fires. And when you reply, click into the existing thread instead of launching a new post. Useful phrases: “Reacting so you know I’ve seen it.” “@Priya — this one’s yours, can you confirm by Friday?” “Replying in-thread to keep it together.” These habits make you easy to work with, which is its own kind of influence.
