Microsoft Teams connector for Simpplr Enterprise Search

Introduction

The MS Teams connector allows Simpplr Enterprise Search to index MS Teams content including Channel Messages that users have access to, making it easily discoverable and searchable directly within Simpplr.

With this connector, you can:

• Bring MS Teams content into Simpplr Enterprise Search so users can find Channel Messages, and Attachments alongside intranet content in one place.

• Use advanced features like autocomplete, hybrid ranking, and Smart Answers on top of MS Teams content.

Indexed content from Simpplr Enterprise Search is available in:

• In main search listing

• Smart answers

Capabilities at a glance

Objects and content supported

Objects - The following object types are indexed and searchable:

• Channel Message (top-level messages only)

Metadata - For each indexed item, Teams captures:

• Title

• URL/ link

• Created time and last modified time

• Message & Subject

• Sender

• Channel

• Attachment Details

Permissions model

Permissions are read from the membership details.
How user and group permissions are synchronized

• Microsoft Teams group and channel memberships are fetched and stored in the ACL index. 

• When a user is added to or removed from the organization or a specific group, the ACL index is updated the next time the ACL sync runs (by default, every hour).

What happens when access is removed for a specific document

• When a user loses access to a Team or Channel, the updated permissions are applied during the next sync cycle.

• The file will no longer appear in that user's Simpplr search results after the sync completes.

Versions and editions supported

• Supported MS Teams editions: All

• Not supported: N/A

Prerequisites

Before you begin, ensure the following:

1. Source system permissions

• You need access to the Microsoft Entra admin center (formerly Azure AD) or the Azure Portal to create and configure your application registration.

• Required Role: Your user account must have at least the Application Developer or Cloud Application Administrator role to register applications and manage their identities.

2. Application / service account

• Ability to register a new Application Registration: You must be able to create a new registration in Microsoft Entra ID. This generates the unique Application (client) ID and Directory (tenant) ID required for your Teams integration.

• Ability to generate Client Credentials (Client Id, Client secret).

• Ability to Authorize the application (Admin Consent and Custom App Upload)

Authentication and security

Uses secure client-credential authentication with Microsoft Graph and enforces Teams-based access controls, while ensuring all indexed data is stored in-region and protected with encryption in transit and at rest.

1. Authentication mechanism
   Describe how Simpplr Enterprise Search connects to MS Teams:

• Auth type: Client credentials

• The following application-level scopes are required. No delegated permissions are needed

  • ChannelMember.Read.All

  • ChannelMessage.Read.All

  • ChannelSettings.Read.All

  • Chat.Read.All

  • Chat.ReadBasic.All

  • Files.Read.All

  • Group.Read.All

  • TeamMember.Read.All

  • TeamSettings.Read.All

  • User.Read.All

2. Data security

• Data storage and residency: Indexed content  from Microsoft Teams are stored within your Simpplr Enterprise Search environment, in the same region as your Simpplr tenant.

• Encryption in transit: Server-side encryption with Amazon S3 managed keys (SSE-S3), TLS encryption in Kafka.

• Encryption at rest: SSL (TLS 1.2 or higher), Auth: OAuth 2.0 Bearer tokens (client-credential).

Permission enforcement:  MS Teams access controls (users and channels) are stored in the ACL index and applied at query time. Search results are always filtered by the signed-in user’s identity and channel memberships.

Setup and configuration

Step 1 - Set Up Azure API Credentials for Microsoft Teams

To connect to Microsoft Teams you need to create an Azure Active Directory application and service principal that can access resources. Follow these steps:

1. Go to the Azure portal and sign in with your Azure account.

2. Navigate to the Azure Active Directory service.

3. Search and Navigate to the “App Registration” service.
   

4. Click on the New registration button to register a new application.
   
   

5. Provide a name for your app, and optionally select the supported account types (e.g., single tenant, multi-tenant).
   

6. Click on the Register button to create the app registration.

7. After the registration is complete, you will be redirected to the app’s overview page. Take note of the Application (client) ID  and Directory (Tenant) ID  value, as you’ll need it later.
   
   
   
    

8. Navigate to Manage →  API permissions section and click on the Add a permission button.
   
   

9. In the "Request API permissions pane, select "Microsoft Graph" as the API.
   
   
   
    

10. Select the permissions mentioned under Authentication and security in scopes or permission required.
    
    
    
    
    

11. Click on the Add permissions button to add the selected permissions to your app.
    
    

12. Click on the Grant admin consent button to grant the required permissions to the app. This step requires administrative privileges. If you are not an admin, you need to request the admin to grant consent via their Azure Portal.
    

13. Under the "Certificates & Secrets" tab, go to Client Secrets. Generate a new client secret and keep a note of the string under the Value column.
    
    
    

Step 2 - Create the connector in Enterprise Application

1. In Simpplr, go to: Enterprise Search → Connectors → Add connector.
   
   

2. Select “Microsoft Teams”.
   
   

3. Enter basic information:

   • Name: (Connector Name for this instance)

4. Provide authentication details:

   • Tenant ID

   • Client ID

   • Secret value
     
     

5. Click “Save” and “confirm”. 

Step 3 - Define sync scope

1. Configure inclusion rules:

   • Not configurable in the current version

2. Configure exclusion rules:

   • Not configurable in the current version

3. Configure Audience based filtering.

   • Include audiences

   • Exclude audiences

Step 4 - Configure sync schedule

• Default schedule: Full crawl at first setup and once in a week, incremental sync every hour.

• Configuration options:

  • No option to configure the sync schedule, however sync can be paused and resumed.

Step 5 - Monitor the sync

1. Monitor the initial full sync status (starts automatically) in the connector dashboard.

Crawling and sync behavior

Describe how the connector works over time:

1.  Initial full crawl

• All the content present in the storage account is indexed during the first run

• How long it may take: Depends on the size of the content.

2. Incremental updates

• Mechanism: Delta tokens provided by source based on previous sync.

• What changes trigger reindexing:

  • New items created

  • Existing items updated

  • Items moved or renamed

  • Items deleted or archived

3. Deletion and permission changes

• Deleted items are removed from index at next sync.

• Permission changes are updated at the next sync cycle.

4. Expected latency

• With the default schedule (incremental sync every hour), changes made to Microsoft Teams content (such as new messages or channel updates) are generally reflected in Simpplr search results within a few hours of the update, subject to content volume and system load.

Field mapping and search experience

1. Default field mapping

Source field (MS Teams) → Index field Simpplr

• Channel Message

• Channel Attachment

• Team Channel

2.  Search experience - how content from this connector appears in search:

• Result layout: (Icon, Connector name, title as link, body(excerpt), Updated Date/ Created Date, object type)
  

• Available filters and facets:

  • Source = Microsoft Teams

  • Updated Date

• Participation in advanced features:

  • Smart Answers / Q&A: Yes

  • Autocomplete: Yes

  • Recommendations / “Suggested for you”: N/A

  • Trending / popular results: N/A

  • Semantic / hybrid ranking: Yes

3. Limits and known limitations

Monitoring and troubleshooting

1. Connector health and monitoring - Describe where admins can see status information:

• Enterprise Search -> Connector name

• Available metrics:

  • Last sync status (Success / Warning / Failed)

  • Last sync time

  • Next scheduled sync

  • Sync Type

  • Total items indexed count

2. Common issues and resolutions. Example pattern:

   • Issue: Authentication failed (invalid credentials or missing scopes)
     Possible causes:

     1. Incorrect client ID or secret (Credentials)

     2. App not granted the required permissions

     3. App granted with the delegated permissions instead of the application permissions

     4. Consent not approved by an admin

   • Resolution:

     1. Verify and re-enter credentials

     2. Confirm required scopes are granted

     3. Re-run admin consent flow

3. When to contact support.

   • Authentication error persists even after trying the above-mentioned resolutions

   • Sync is stuck in the Pending state.

   • Sync is in progress but no documents are getting ingested.

   • Sync failure with cancelled error (when not cancelled manually)

   • Incomplete or Partial sync. 

4. When contacting, Support, include:

   1. Connector name and instance ID (if available)

   2. Organization URL

   3. Approximate time and date of the issue
