Choose Team Site vs Communication Site: SharePoint Admin Guide

SharePoint admins often need to decide between creating a team site and a communication site for a new project or department. Both site types serve different purposes and come with distinct features, default settings, and integration behaviors. This article explains the core differences between team sites and communication sites, including their intended use cases, default permissions, connected services, and template options. By the end, you will know exactly which site type fits each business scenario and how to configure it in the SharePoint admin center.

What Are Team Sites and Communication Sites?

A team site is the default SharePoint site type that is automatically created when you provision a Microsoft 365 Group. It is intended for collaborative work among a defined set of members who need to co-author documents, manage tasks, share a calendar, and communicate via a group mailbox. Every team site is connected to a Microsoft 365 Group, which provides a shared identity, a group email address, a shared calendar, a Planner plan, and a OneNote notebook. The membership of the group controls access to the site, and the site can be either private (invite only) or public (anyone in the organization can join).

A communication site is a standalone SharePoint site that is not connected to a Microsoft 365 Group. It is designed for publishing news, reports, and information to a wider audience, such as the entire organization or external partners. Communication sites do not have a group mailbox, shared calendar, or Planner integration. They use SharePoint groups for permissions, and the default access is read-only for most users, with only site owners having edit rights. Communication sites are ideal for intranet portals, department home pages, or project dashboards where the primary goal is information dissemination rather than document co-authoring.

Prerequisites for Both Site Types

Before creating either site type, confirm that SharePoint is enabled for your tenant and that you have at least SharePoint admin or Global admin permissions. For team sites, the Microsoft 365 Group creation must not be restricted by naming policies or blocked by conditional access rules. For communication sites, no additional services are required, but you must ensure that the site URL does not conflict with existing site collections. Both site types can be created from the SharePoint admin center or via the SharePoint Online Management Shell.

Steps to Create a Team Site in the SharePoint Admin Center

1. Open the SharePoint admin center
   Sign in to Microsoft 365 admin center and select SharePoint from the navigation menu. Alternatively, go directly to admin.microsoft.com/SharePoint.
2. Navigate to Active sites
   In the left navigation pane, click Active sites. This page lists all existing site collections in your tenant.
3. Click Create
   On the toolbar at the top of the Active sites page, click the Create button. The site creation panel opens.
4. Select the Team site template
   In the Choose a template section, select Team site. You will see two options: Team site (connected to a Microsoft 365 Group) and Team site (classic). Choose the modern team site connected to a Microsoft 365 Group.
5. Enter site details
   Provide a site name, a description, and a URL path. The site name becomes the group name and the email alias for the Microsoft 365 Group. Set the privacy setting to Private or Public.
6. Assign owners and members
   In the Owners and Members fields, add the users or security groups. Owners will have full control, and members will have edit access. You can also add guests from outside your organization.
7. Click Finish
   Review the settings and click Finish. SharePoint provisions the site, creates the Microsoft 365 Group, and sends invitations to the owners and members.

Steps to Create a Communication Site in the SharePoint Admin Center

1. Open the SharePoint admin center
   Go to admin.microsoft.com/SharePoint and sign in as a SharePoint admin or Global admin.
2. Go to Active sites
   Click Active sites in the left navigation pane.
3. Click Create
   On the toolbar, click the Create button to open the site creation panel.
4. Select the Communication site template
   In the Choose a template section, select Communication site. You will see three design options: Topic (for news and articles), Showcase (for visual content), and Blank (no predefined layout). Choose the one that matches your content style.
5. Enter site details
   Type a site name, a description, and a unique URL. The site name does not create a Microsoft 365 Group, so there is no email alias or group calendar.
6. Set site permissions
   By default, the site is set to allow everyone in the organization to read content. You can change this to specific users or security groups by selecting Edit permissions. Owners will have full control, and members can edit if granted.
7. Click Finish
   Review all settings and click Finish. The communication site is created immediately without any group provisioning.

Common Mistakes When Choosing Between Team Sites and Communication Sites

Selecting a team site when you only need to publish information

If you create a team site for a department that only needs to broadcast announcements, you will end up with a Microsoft 365 Group that includes a mailbox, calendar, and Planner that no one uses. This creates clutter in the Global Address List and may confuse users. Instead, use a communication site for pure information publishing.

Selecting a communication site when you need document co-authoring and task management

Communication sites lack the group-connected services that make collaboration seamless. If your team needs a shared calendar, a Planner board, or a group mailbox, a communication site will require manual workarounds. Create a team site instead to get these features out of the box.

Forgetting to set privacy on a team site during creation

If you leave the privacy setting as Public, anyone in your organization can join the team site and its associated Microsoft 365 Group without approval. This can lead to unintended access to sensitive documents. Always set the privacy to Private for projects that contain confidential data.

Ignoring the impact on Microsoft 365 Group limits

Each Microsoft 365 Group has a maximum of 1000 owners and members combined. If you plan to have more than 1000 users collaborate on a site, a communication site with SharePoint groups is a better choice because it can support up to 100,000 users.

Team Site vs Communication Site: Key Differences

Item	Team Site	Communication Site
Microsoft 365 Group	Connected by default	Not connected
Default permission	Edit for members	Read for everyone
Shared calendar	Included	Not included
Planner integration	Automatic	None
Group mailbox	Created automatically	Not created
Intended audience	Team members	Broad audience
Maximum users	1000 per group	100,000 per site
Template options	Team site, Team site classic	Topic, Showcase, Blank
Creation from admin center	Yes	Yes

Now you can confidently choose between a team site and a communication site based on your collaboration or publishing needs. For a team that needs to co-author documents and manage tasks, create a team site with a Microsoft 365 Group. For broadcasting news or hosting a department portal, create a communication site. As an advanced tip, use the SharePoint admin center to set a site creation policy that restricts which templates users can choose, preventing accidental creation of the wrong site type.
