MS-700 Configure and Manage a Teams Environment Practice Question
An organization is currently in Islands mode during a migration from Skype for Business Server to Microsoft Teams. Users report that they receive chats in both clients, causing confusion. Which coexistence mode should the administrator implement to ensure all incoming chats and calls are received exclusively in Microsoft Teams?
⚠ Common exam trap
MS-700 often tests the distinction between the four coexistence modes, and candidates confuse 'Teams collaboration' (channels/files only) with full Teams chat and calling, leading them to pick option C or D.

Correct answer & explanation
✓
Teams Only
Teams Only mode is the coexistence mode that routes all incoming chats, calls, and meetings to Microsoft Teams exclusively, removing the dual-client confusion of Islands mode. When a user is in Teams Only, Skype for Business clients are effectively disabled for communication, and all new conversations land in Teams. This is the required end-state for organizations completing a Skype for Business to Teams migration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Skype for Business only
Why it's wrong here
Setting users to Skype for Business only mode forces all communication to the legacy client while disabling Teams capabilities for meetings and chat. This configuration is typically used when an organization is not yet ready to introduce Teams features to its user base or during early pilot stages of planning.
- ✓
Teams Only
Why this is correct
Teams Only mode routes all incoming calls and chats to the Teams client regardless of where the sender originates the communication. It is the target state for all migrations, ensuring that users utilize the full feature set of Teams while decommissioning legacy Skype for Business functionality for that specific user.
- ✗
Skype for Business with Teams collaboration
Why it's wrong here
This mode allows users to continue using Skype for Business for chat and calling while introducing Teams specifically for group collaboration and channel-based communication. It does not solve the issue of receiving chats in multiple clients because private messaging remains anchored to the legacy Skype for Business client interface.
- ✗
Skype for Business with Teams collaboration and meetings
Why it's wrong here
In this specific configuration, users use Skype for Business for chat and calling, but utilize Teams for scheduling and attending meetings. While it introduces more Teams functionality, private chats and person-to-person calls are still handled by Skype for Business, which does not meet the requirement of centralizing all traffic.
