Introduction

Microsoft Teams has introduced a groundbreaking feature allowing users to react with multiple emojis—up to 20 per message. This update enhances digital communication by enabling richer emotional expression while reducing reply clutter. IT professionals and Teams administrators should understand its implications for workplace collaboration and user engagement.

Learning Objectives

  • Learn how to enable and use multi-emoji reactions in Microsoft Teams.
  • Understand the technical backend updates supporting this feature.
  • Explore best practices for managing emoji reactions in enterprise environments.

1. How to Enable Multi-Emoji Reactions

Verified Command (Teams Admin Center PowerShell)

Set-CsTeamsMessagingPolicy -AllowMultipleEmojiReactions $true

Step-by-Step Guide:

1. Open PowerShell with admin privileges.

2. Connect to Microsoft Teams using `Connect-MicrosoftTeams`.

  1. Run the command above to enable multi-emoji reactions for your organization.

4. Verify the setting via:

Get-CsTeamsMessagingPolicy | fl AllowMultipleEmojiReactions

2. Custom Emoji Deployment via Teams Admin Center

Verified Process

  1. Navigate to Teams Admin Center > Messaging Policies.
  2. Select your policy and enable “Allow custom emojis”.
  3. Users can now upload custom emojis (PNG/SVG, 32x32px) via Teams settings.

Technical Note:

Custom emojis are stored in SharePoint backend (tenant-specific). Monitor storage with:

Get-SPOStorageEntity -SiteUrl <TeamsSiteURL>
  1. Monitoring Emoji Usage via Microsoft 365 Audit Logs

Verified KQL Query (Advanced eDiscovery)

OfficeActivity | where Operation == "TeamsEmojiReactionAdded" 
| summarize Count=count() by UserId, EmojiType

Steps:

  1. Access Microsoft 365 Compliance Center > Audit Logs.
  2. Run the query to track reaction trends or potential misuse.

4. API Security: Teams Emoji Reaction Endpoint

Verified API Call (Graph API)

POST https://graph.microsoft.com/v1.0/chats/{chatId}/messages/{messageId}/reactions 
Content-Type: application/json 
{ 
"reactionType": "emoji", 
"emoji": "🔥" 
}

Security Note:

  • Requires `Chat.ReadWrite` permission.
  • Audit API calls via Azure AD Conditional Access policies.

5. Disabling Reactions for Compliance (GCC High)

Verified Command

Set-CsTeamsMessagingPolicy -Name "RestrictedPolicy" -AllowReactions $false

Use Case:

For highly regulated environments, disable reactions entirely to prevent data leakage via emoji metadata.

What Undercode Say

  • Key Takeaway 1: Multi-emoji reactions improve engagement but require monitoring to prevent spam (e.g., 20 😠 reactions on a critical announcement).
  • Key Takeaway 2: Custom emojis introduce branding opportunities but also security risks (malicious SVG/PNG uploads).

Analysis:

This update reflects Microsoft’s focus on user experience, but IT admins must balance functionality with governance. Emoji reactions generate metadata that could be exploited in social engineering attacks (e.g., identifying active users). Future integrations may include sentiment analysis APIs to flag toxic emoji combinations (e.g., 💣 + 👨‍💻).

Prediction

By 2025, expect AI-driven emoji suggestions (e.g., Teams recommending 🎉 for project milestones) and stricter compliance controls (auto-deletion of 🚩 reactions in financial chats). Proactive policies will be critical as emojis evolve into a workplace communication standard.
