3.2Conversations, mentions & messages
The essentials in 30 seconds
- Reply IN the thread: a new message to respond breaks the context and scatters the discussion.
- @No one to target; @canal/@team only if everyone really has to read.
- A reaction (👍/✅) replaces “ok”: acknowledge receipt without notifying the entire channel.
Nassim’s thread — Conversations, mentions & messages
Nassim participates in several conversations in a channel. He must reply in the thread, mention the right people and avoid unnecessary notifications.
Continuation of the common thread: a digital services SME in Algiers structures its exchanges.
1. Understand
Communicating in Teams is not “chatting any way you want”. Two rules structure everything: reply in the thread (the Reply button under the message, not a new message that breaks the context), and use @mentions to contact the right person (@Name) or the right group (@channel, @team). A well-placed notice notifies precisely who should read; its absence, or its excess, are the two classic faults.
You'll master threads, mentions (person/channel/team), reactions (a thumbs up is better than an "ok" that notifies everyone), and formatting important messages (subject, urgency) — the etiquette that makes Teams readable instead of noisy.

@No one to target; @canal/@team only if everyone really has to read.
A reaction (👍/✅) replaces “ok”: acknowledge receipt without notifying the entire channel.
“Important”/“Urgent” are reserved for the critic: their trivialization makes them useless.
🔎 Concrete example — Concrete example — Conversations, mentions & messages
In a channel, reply to an existing message via Reply (below the message) rather than with a new message: the thread remains consistent.
Call someone with @First Name: they receive a targeted notification. Avoid @channel/@team unless EVERYONE has to read.
On an info message, put a reaction (👍/✅) instead of responding “ok”: less noise for everyone.
Write a message with the formatting option (“A” icon): add a clear subject for a long or important message.Readable and targeted Teams conversations — the difference between a useful channel and one that is muted.
Section vocabulary
- Thread
- The response ATTACHED to a message (Reply button): the context remains grouped, unlike a new isolated message.
Simple example: Nassim uses “Discussion thread” in his daily life for conversations, mentions & messages.
What it is not: Confusing “Discussion thread” with a setting that has no effect on the organization of work.
Reflex: Does this clarify who does what, where and when?
- @mention
- Call precisely: @Firstname (one person), @channelname (entire channel), @teamname (entire team) — notify the correct recipients.
Simple example: Nassim uses “@mention” in his daily life for conversations, mentions & messages.
What it is not: Confusing “@mention” with a setting that has no effect on the organization of work.
Reflex: Does this clarify who does what, where and when?
- Reaction
- An emoji (thumb, heart, ✅) on a message: acknowledge/approve without posting a message that notifies everyone.
Simple example: Nassim uses “Reaction” in his daily life for conversations, mentions & messages.
What it is not: Confuse “Reaction” with an adjustment that has no effect on the organization of work.
Reflex: Does this clarify who does what, where and when?
- Important/urgent message
- The editing option that marks “Important” (banner) or “Urgent” (repeated notification): to be reserved for the truly critical.
Simple example: Nassim uses “Important/urgent message” in his daily life for conversations, mentions & messages.
What it is not: Confusing “Important/urgent message” with a setting that has no effect on the organization of work.
Reflex: Does this clarify who does what, where and when?
- Announce (announcement)
- A large headline message format for channel highlight communications.
Simple example: Nassim uses “Announce (announcement)” in his daily life for conversations, mentions & messages.
What it is not: Confusing “Announce (announcement)” with a setting that has no effect on the organization of work.
Reflex: Does this clarify who does what, where and when?

Ready-to-say script — Conversations, mentions & messages (25 sec)
“Chat in a channel vs private, use @mentions, reactions, threads and important messages. I rely on this key point: respond in the thread: a new message to respond breaks the context and scatters the discussion.”

Frequently asked questions
Why avoid @team / @canal?
Because they notify EVERYONE: used for a message that only concerns two people, they generate dozens of unnecessary notifications and push people to turn off alerts. Reserve them for truly collective announcements.
Message posted in error: can I correct it or delete it?
Yes: hover over your message → … → Edit (it will then be marked “Modified”) or Delete. Correct rather than repost: this keeps the thread clean.
