When you create a new site in SharePoint, the first decision is choosing between a Team Site and a Communication Site. Many site owners pick the wrong type because the names sound similar. This choice affects how people collaborate, how content is organized, and which Microsoft 365 features are available. This article explains the core differences between Team Sites and Communication Sites. It provides a practical checklist to help you decide which site type fits your project. You will also learn about common setup mistakes and how to avoid them.
Key Takeaways: Choosing the Right SharePoint Site Type
- Microsoft 365 Group connection: Team Sites are linked to a Microsoft 365 Group with a shared mailbox and calendar. Communication Sites are not.
- Site template selection: Choose Team Site for ongoing collaboration with a small group. Choose Communication Site for broadcasting content to a large audience.
- Navigation and layout: Team Sites use a horizontal navigation bar and a team news web part. Communication Sites use a hero web part and a vertical navigation layout by default.
Team Site vs Communication Site: Core Differences and Design Intent
SharePoint offers two primary site templates for different collaboration and communication scenarios. A Team Site is designed for a group of people who work together on shared documents, tasks, and projects. Each Team Site is connected to a Microsoft 365 Group, which provides a shared Outlook mailbox, a calendar, a Planner board, and a shared notebook in OneNote. This connection means that when you create a Team Site, you also create a Microsoft 365 Group. Membership in the group controls access to the site and all connected services.
A Communication Site is built for broadcasting information to a broad audience, such as an intranet portal, a news hub, or a department landing page. Communication Sites do not have an associated Microsoft 365 Group. They use Azure AD groups or SharePoint groups to manage permissions. The default layout of a Communication Site emphasizes visual impact with a hero web part, large images, and a flexible design. Users who visit a Communication Site typically consume content rather than co-author documents.
Microsoft 365 Group Membership and Site Permissions
In a Team Site, membership is managed through the Microsoft 365 Group. Adding a user to the group gives them access to the SharePoint site, the shared mailbox, the calendar, and the Planner board. Removing a user from the group revokes access everywhere. In a Communication Site, you control permissions directly through SharePoint site permissions or through Azure AD groups. This separation means you can give a large number of people read-only access without giving them a mailbox or calendar.
Default Features and Web Parts
A Team Site starts with a team news web part, a document library, and a conversations web part that connects to the group Outlook inbox. The navigation bar runs horizontally at the top. A Communication Site starts with a hero web part, an events web part, and a news web part. The navigation is vertical on the left side by default. Communication Sites also include a site design panel that lets you apply branding without custom code.
Checklist to Decide Between Team Site and Communication Site
Use the following checklist to evaluate your project requirements. Answer each question with yes or no. The site type with more yes answers is the better fit.
- Does your team need a shared mailbox and calendar?
If yes, choose Team Site. The Microsoft 365 Group provides these tools automatically. Communication Sites do not include a group mailbox. - Will most users edit documents and collaborate in real time?
If yes, choose Team Site. Co-authoring and version history are built into the default document library. Communication Sites are read-only for most visitors. - Is the audience larger than 100 people who do not need editing rights?
If yes, choose Communication Site. You can grant read access to thousands of users without creating a Microsoft 365 Group. Team Sites become difficult to manage at scale. - Do you need to broadcast news, announcements, or events to the whole organization?
If yes, choose Communication Site. The hero web part and news web part are designed for high-visibility content. Team Site news is visible only to group members by default. - Will the site be used for a project that lasts less than six months?
If yes, choose Team Site. You can archive or delete the Microsoft 365 Group when the project ends. Communication Sites are better for permanent portals. - Do you need to apply custom branding, layout, or navigation?
If yes, choose Communication Site. The site design panel and vertical navigation give you more control. Team Sites have a fixed horizontal navigation and fewer layout options. - Will the site integrate with Planner, Teams, or Power Automate?
If yes, choose Team Site. These tools connect directly to the Microsoft 365 Group. Communication Sites require manual connections to each service.
Common Mistakes and Limitations When Choosing a Site Type
I created a Team Site but I only need to share news
If you use a Team Site to broadcast news, every visitor who needs to see the news must be added to the Microsoft 365 Group. This action gives them a mailbox and calendar they do not need. It also increases the size of the group, which can cause performance issues in Outlook and Teams. The correct solution is to delete the Team Site and create a Communication Site instead.
I created a Communication Site but my team needs to edit documents together
A Communication Site does not have a document library with co-authoring as the default view. You can add a document library manually, but users will not have a shared mailbox, calendar, or Planner board. The team will need to use separate tools for task management and email. The correct solution is to delete the Communication Site and create a Team Site with the group features.
I cannot convert a Team Site to a Communication Site after creation
SharePoint does not provide a built-in conversion tool. If you create a Team Site and later decide you need a Communication Site, you must create a new site from the Communication Site template. You can migrate content manually by moving documents and pages between the two sites. The Microsoft 365 Group associated with the old Team Site remains active until you delete it separately.
External sharing does not work the same way for both site types
In a Team Site, external sharing settings are controlled at the Microsoft 365 Group level and the SharePoint site level. If you disable group-level external sharing, external users cannot access the site even if SharePoint sharing is enabled. In a Communication Site, external sharing is controlled only at the SharePoint site level. This difference can cause confusion when you try to share a Team Site with a vendor or partner.
Team Site vs Communication Site: Key Differences
| Item | Team Site | Communication Site |
|---|---|---|
| Microsoft 365 Group | Created automatically | Not created |
| Shared mailbox and calendar | Included | Not included |
| Default navigation | Horizontal top bar | Vertical left panel |
| Primary audience size | Small team under 100 | Large audience unlimited |
| Co-authoring default | Enabled in document library | Not default |
| Branding and layout control | Limited | Flexible with site design |
| Integration with Planner and Teams | Automatic | Manual |
| External sharing control | Group and site level | Site level only |
After you run the checklist and review the table, you can create the correct site type the first time. Start by opening the SharePoint admin center and selecting Active sites. Click Create and choose either Team Site or Communication Site based on your checklist results. If you are unsure, create a Communication Site for broad communication and a Team Site for collaborative projects. You can also use the SharePoint look book to see example designs for each site type before you create your site.
