Clear communication practices help everyone stay on top of what matters. These guidelines keep our Teams channels functional and easy to follow. They apply to both channel messaging and personal chat.
Channel messaging
Mentioning practices
A message posted to a channel is visible to all members without any mention. Use @channel or @team mentions only when the matter is genuinely urgent and relevant to everyone. Direct a message intended for a specific person with an @mention — this sends a notification only to them.
Reacting to messages
When you have read a message, add a reaction (e.g. 👍) – especially when the sender asks you to. A reaction lets the sender know that the message has reached you, and no separate ping is needed.
Subject lines
Always add a subject line to a channel post — it appears in the feed and immediately tells the reader whether the message is relevant to them.
Announcements
Important notices can be posted as an Announcement, which lets you add an image or background colour to the heading. Select Announcement (megaphone icon) as the post type → add a subject line and an image if you wish.
Important mark
You can add an Important mark to a channel post, which gives the message a red exclamation mark and the text “IMPORTANT!”. This is a good alternative to @channel mentions for urgent messages. The setting can be found under the + icon → Set delivery options → Important.
Replying and reacting
Always respond to the original message using Reply — this keeps the conversation threaded. React with an emoji when a separate reply is not needed. You can edit a message after sending it: hover over the message → More options (…) → Edit.
Choosing the right channel
Post your message in the channel that matches the topic. Before asking a question in a channel, use the Teams Search function (magnifying glass icon at the top) — the answer may already exist in earlier messages.
Personal chat
Personal chat is suited for brief, one-to-one or small group communication. Use chat when the topic does not belong in a channel or when you need a quick reply from a specific person.
In chat, you can set a delivery option for your message via the + icon → Set delivery options:
- Important — the message receives an Important mark. Also available in channel posts.
- Urgent — the recipient receives repeated notifications every 2 minutes for 20 minutes until they read the message. Use only in genuine emergencies. Note: Available in chat only.
If needed, make a Teams call — but first check with a chat message that the call is convenient, even if the person’s status shows as available.
Status
Keep your status up to date so that others know when you are reachable. Your status is shown next to your profile picture — the options are Available (green), Busy (red), Do not disturb (red with a line), Be right back, or Appear away (yellow). Teams automatically sets your status to Busy during events scheduled in your Outlook calendar.
