Microsoft Teams help > Teams and channels
Teams are collections of people, content, and tools that center around different projects and jobs within an organization. In Microsoft Teams, team members can have conversations and share files, notes, and more all in one place.
Select Teams in the sidebar and then open a team to see its channels. You need to be a team owner to create a team or add members, but anyone on the team can add channels.
Channels are there to help keep team conversations organized. You can dedicate channels to specific topics, projects, disciplines—whatever you like!
To add a channel, choose the more icon next to the team name and select Add channel.
In this topic
Every team you belong to will show up in your teams list, either in your favorites or inside the More menu at the bottom of your list.
If you're trying to join a specific team within your organization, click Add a team at the bottom of your teams list. In the search box in your teams gallery, start typing the name of the team you want to find. Press Enter, and your teams gallery will show you a collection of teams that match your search. Find the team you're looking for and click Join team.
Any team in Microsoft Teams can hold up to 999 people.
To change the privacy settings for your team from public to private (or vice versa), click the more icon next to the team in your teams list. Then select Edit team. That will open up a view that lets you edit the privacy settings for your team, and you can select either 'public' or 'private'.
To join a public team, click on the Add a team link that appears at the bottom of your teams list. You'll see your teams gallery, including a bunch of suggested teams. Go to the team you'd like to join and then click Join team.
Private teams can only be joined if the team owner adds you to them. They also won't show up in your teams gallery. On the other hand, public teams are visible to everyone from the teams gallery and you can join them without getting approval from the team owner.
This Onboard your teams video shows you what team owners can do. A transcript of the video narration and procedural information accompany the video.
Team owners can add and remove members. They have the ability to edit or delete a team, and to change the team picture. They can also…
Set team members' permissions for channels, tabs, and connectors.
Control @[team name] mentions that will notify everyone on the team.
Allow @channel or @[channel name] mentions, which will notify members who’ve favorited the channel.
Allow usage of GIFs, stickers, and memes.
If you can't create a team, it's probably because your organization has decided to only enable team creation for a limited group of people.
If you’re the team owner, click the more icon next to a team name to see some of the team management actions you can take.
Click on View team to manage members, channels, and general team settings. You can change your team picture, enable @team and @[team name] mentions, allow team members to send GIFs and emoji, and more.
If you’re a team member, you’ll be able to see some of these things, but you won’t be able to make too many changes.
Does your team need a new name? Team owners can take care of that in no time.
Click the more icon next to a team name and then click Edit team.
Team owners can change the name of team channels by clicking the more icon next to a channel name, and select Edit this channel.
If you want to delete a team (and you’re the team owner), click the more icon next to your team name and select Delete the team. Your team will be permanently removed.
Remember: Deleting a team will also remove the team mailbox and calendar from Exchange.
Team owners and IT admins can recover deleted teams for up to 30 days. For more info, click https://aka.ms/groupssoftdelete.
To create a team, click on Add a team at the bottom of your teams list. Navigate to the first tile in the Teams Discovery view and then select Create a team.
From there, you can name your team, add a description, and edit the team's data classification. Once you've done that, you can invite team members, groups, or even entire distribution lists to join your team.
When you create a team in Microsoft Teams, you also get the things that come with Office 365 groups, like a group inbox and calendar, SharePoint site, and OneNote. So, the group will show up in products like Outlook along with your teams.
Each team you create in Microsoft Teams also has a corresponding Office 365 group. Each team will also have a group mailbox in Outlook that people outside your team can send emails to. That way, you can actually use your new Outlook group as an email address for your whole team.
To add a team in Microsoft Teams to an existing Office 365 group, first navigate to the teams gallery by clicking on Add a team at the bottom of your teams list. Once you're there, select the Create a team option. You'll see a link that will take you to a list of all the Office 365 groups that you're currently able to add a team to. From there, all you have to do is select the group you want, and add your team! You'll end up in the General channel for the team you decided to add to your Office 365 group.
If you're a team owner, you can add people to your team. In the team list, click the more icon next to the team name, and click Add members. You can also click View team, and add people in the Members tab. If you want, you can even add multiple people by using a distribution group.
In the General channel, you can @mention the team by typing @team or @[team name] in the compose box. We'll also send an email on your behalf. FYI, a team owner has to enable @team mentions for them to work.
If you want to make someone the owner of an existing team, click the more icon next to the team name in your list, then select View team. Find the person in your team list, then, under the column labeled Role, click Member, and then select Owner from the dropdown menu.
You're currently limited to 250 teams per account.
If you want only certain people to be able to create teams, contact your IT admin, who can set permissions for your organization.
Anyone on the team can add a channel and participate in the conversations in a channel. Everyone on the team can see the conversations in a channel. Channels keep team conversations organized and you can dedicate channels to specific topics, themes, or subjects.
This Teams and channels video reviews how to create a team and then shows you how you can create and favorite a channel. A transcript of the video narration and procedural information accompany the video.
Channels allow teammates to have focused conversations about specific topics. Every team has its own set of channels (starting with the General channel), and the members of that team get to decide what they want the rest of their channels to focus on. Some channels are devoted to specific projects, some are for areas of interest. Some channels are just for fun. Every channel belonging to a team is completely public to all the team members, so everyone can feel free to join in a channel conversation.
If you spot a channel that looks interesting or is relevant to you, you have the option of following (or, favoriting) it. You’ll always have the General channel for every team favorited and there's no way to remove it from your favorites, either.
To favorite a channel, just click the star icon next to a channel name. That way, it will stay visible in your teams list. You'll also be able to see if there's recent activity in your favorite channel because its name will appear in bold text. If someone @mentions you in one of your favorite channels, you'll see a red number count next to the channel name that tells you the number of @mentions you received.
You won't be able to see the team channels that you don't favorite by default, but if you ever want to take a look at all the other channels belonging to a team, click on the text that appears at the bottom of your current favorites telling you how many more channels belong to that team. That will open up a list of all the channels you haven't favorited. If you see a channel that looks interesting, you've got the option of favoriting it from there.
Everyone on a team that's following a specific channel will be able to see if that channel is active thanks to the bold channel name, but they will only get notifications if they're specifically @mentioned within that channel. If you get @mentioned in a channel you're not following, you'll get a notification in your Activity feed.
If you're a team owner, it's easy to add someone to a channel; just add them to the team that the channel belongs to!
To do that, start from your teams and channels list. Click the more icon next to the team name, and then click Add members.
Another option is to click View team and then add people from the Members tab. Once someone has been added to a team, they'll automatically have access to all that team's channels.
Once you're finished adding people to a team, it's a good idea to @mention them in your new channel so they know that it exists.
To let someone know you created a new channel, click in your compose box and @mention them (by typing @ and then their name).
To see all the channels in a team, click on the link that appears below all the channels you've favorited in that team. That will show you a full list of every channel belonging to that team.
To follow a channel, click on the more icon next to the channel name in your teams list and then select Follow this channel. From then on, you'll receive direct notifications whenever there's new channel activity.
You can also catch up on all your followed channels by going to your Activity feed and filtering your feed to Follows.
To delete a channel, right-click the channel as it appears in your teams and channels list and then select "Delete this channel." There are a couple caveats, though: First, only team owners can delete a channel, so if you want a channel deleted and you're not one of the team owners, now you know who to ask. Also, once you delete a channel, you'll also lose its entire conversation history. However, the OneNote sections associated with that channel will still show up in your team's SharePoint site.
We don't currently have private channels, but we're working on it! To keep things private in the meantime, you can create a new team and invite a more select audience.
When you join a new team, a few channels automatically appear in your favorites. That's intentional. To help get you up and running, we decided to automatically favorite the top five most popular channels in every new team you join. This gives you a sense of how to interact with your new team, and it also shows you where all the action is. You can always unfavorite any of these channels later on!
For teams that have fewer than five channels, we'll automatically favorite new channels as they're created until you reach five channels.
Every once in a while, you may notice that a new channel has popped up in your favorites. Here's why it's happening: Whenever you join a new team, we automatically favorite its five most popular channels for you.
However, some teams contain fewer than five channels, so in those cases, we'll add all their existing channels to your favorites and then gradually add new channels as they're created.
If you can't change team settings, it's most likely because you're not a team owner.

Set member permissions (like allowing them to create, update, or delete channels and tabs).
Allow @team or @[team name] mentions in a channel.
