Lately, we have been using collaboration tools depending on the type of communication. When it comes to Microsoft space, we use

  1. Outlook and Exchange for persistent messaging.
  2. Lync/Skype for Business for real-time communication.
  3. SharePoint for effective document sharing and team collaboration.

A New-Gen Collaboration Tool

Above tools work in sync to cater our communication need whether it is message based, real-time or documents and other information sharing across boundaries. They work relative to each other but still they’re separate programs which we have to run and juggle between continuously. It demands a lot of context switching to access information organized in each tool i.e. to view email in Outlook or Exchange, Skype for chat and SharePoint workspace to access files or pages. Microsoft Teams aka Teams brings together all these facets of communication under a single roof.

Benefits of Microsoft Teams include:

  • Real-time and quick access to messages, documents, notes, and meetings.
  • Communication with teammates who are online.
  • Reducing the need to send redundant emails while it provides a notification for uploaded documents across the channel.
  • Conversation across or outside the organization through chats, meetings, file sharing, host audios, videos, and conference calls, thus relegating the need to send information using Skype or Outlook.
  • Share and host files with Office 365 apps such as SharePoint, Word, Excel, Power BI and more.
  • Increase teamwork and productivity by integrating Microsoft and various third-party services.
  • Security and compliance capabilities.

Relation with SharePoint

Both Microsoft Teams and SharePoint team site are common in a way that both are streamlined by topic, project, collaboration or team of people. Teams and channels often follow a structure that is similar to the SharePoint team and project sites. To store the channel documents, it is adamant with the fact that every Microsoft Team has a modern team site working in SharePoint development. Also, there is an associated folder inside SharePoint document library for each channel in Microsoft Teams.

Relation with SharePoint

SharePoint Documents in MS Teams

There are a number of positive collaborating Teams’ documents in SharePoint. Files in Teams are easily discoverable in SharePoint search. SharePoint supports previewing documents for more than 300 file types which can be accessed directly from the Files tab in MS Teams. Users don’t have to juggle between tabs to access their files as there is an “Open in SharePoint” option that browses to the SharePoint modern team site.

SharePoint search

SharePoint Pages in MS Teams

You can also add SharePoint page as a tab in MS Teams. Building a tab is a much simpler approach compared to the typical approach of building a whole website. SharePoint team site’ home page can appear in the same user interface thus providing the intuitive user experience.

Add SharePoint page

It also provides an interface to add the whole document as a tab that is easily accessible by all the members in a team.

Sharepoint framework extension

Conversations and News

SharePoint’ Discussion and Newsfeed lists satisfy conversations to some extent but due to their usability issues, they were never able to satisfy most customer needs. Now it is also possible to integrate Yammer with SharePoint within Office 365 but it does not provide an extensive approach.

You can directly have a conversation regarding a document and other shared information in MS Teams.

SharePoint’s Discussion

The conversation is also shown directly under the Conversations tab in the channel so that all the members of the team are aware of it.

Conversations tab

Microsoft Teams also bubble up team news that helps transcend the conversation. To easily highlight an update and announce news items. SharePoint news can be configured as messages in the conversation thread and Modern SharePoint news as web parts in hub sites.

How to Determine if Your SharePoint Site is Connected to MS Teams?

First, you need to know whether you are on a modern or classic team site collection.

Click on the Settings gear on the root site to find Site information option is available or not. If you cannot see the option, you have a classic page on a classic site.

Classic Vs Modern Page

If Site information option is available, you are sure that you have a modern page. But wait, still, you may have a classic site. Click Site information link. A panel Edit site information will be opened on the right. If it contains Privacy settings then you have a modern team site connected to an Office 365 group. If not, you have a classic team site containing a modern page.

Classic site vs Modern Site

Site information panel – Classic site (modern page) vs modern site

Now, you can easily determine if you have a classic or a modern team site. To add a Team for a classic site, you need to groupify the site by adding an Office 365 group. For modern team site or classic team site after adding Office 365 group, you can easily add a Team.

Connect Office 365 Group with the Classic Team Site

You can control whether global or SharePoint admin can connect classic team site to Office 365 group.

  • Log in to Office 365 using global or SharePoint admin account.
  • Click app launcher icon at the top-left corner and select Admin to open Office 365 admin center.Launcher icon

SharePoint Web Parts as Tabs

You can use SharePoint Framework web parts as tabs in MS Teams. This will leverage SharePoint users to use Teams tab to easily reach their web-parts. This considerably eases Teams tab building process as the hosting of SharePoint Framework web parts is automatic without having to call external services. The tab also provides familiar web part edit panel to set tab properties.

Surfacing Your SharePoint Framework Solution as a Microsoft Teams Tab

You can build Microsoft Teams tabs using SharePoint Framework v1.8 and later.

Note: Use npm install -g @microsoft/generator-sharepoint command to install/update to latest SharePoint Framework version. The functionality is only applicable in targeted release tenants.

Create a New Web Part Project in Your Framework Environment

  • Create a new web part by following Step 2 – To Create SPFx web part from this link.
  • One can do modification in the Web Part as per his/her requirement.

Packaging and Deploying Your Web Part to SharePoint

Make sure that you are in the project directory inside the console.

  • Bundle your solution by executing below command

gulp bundle –ship

Gulp bundle
  • Package your solution by executing below command

gulp package-solution –ship

Gulp package-solution

The above command creates a package teams-tab-webpart.sppkg in sharepoint/solution folder in your project directory.

Creates a package teams

Now, you will need to deploy the generated package inside your tenant app catalog.

  • Navigate to the app catalog site for your tenant.
  • Upload or simply drag and drop the client-side package to the app catalog i.e. Apps for SharePoint list.

SharePoint prompts a dialog to deploy client-side solution package because this is a full-trust solution.

You can observe that the domain in the dialog says SharePoint Online because the content is rendered from the Office 365 CDN or served up from tenant app-catalog, based on tenant settings.

  • Click Deploy.Deploy

Please note that there are no error messages inside the App Package Error Message column inside the app catalog.

Once deployed, the web part is directly available across SharePoint Online sites.

Packaging and Deploying Your Web Part as a Microsoft Teams Tab

Your tenant needs to support Side Loading of external apps for Teams in order to deploy an app. You need to explicitly deploy Microsoft Teams app to a Team.

Below setting has to be enabled only once in a tenant to configure side-loading of apps in Teams.
