MS-700 Manage Teams, Channels, Chats, and Apps Practice Question
You are a Teams administrator. A user reports that they cannot start a new chat with a specific external user who uses Teams in a different organization. You have verified that external access is enabled for the domain of the external user. What should you check next?
⚠ Common exam trap
The trap here is focusing only on your own organization's settings and forgetting that external access must be reciprocated by the other organization.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verify that the external user's organization has allowed external access to your domain.
External access for chats requires that both organizations allow each other's domains. Even if your organization permits the external domain, the external organization must also permit your domain. This mutual configuration is often overlooked, leading to the inability to start chats.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Confirm that the user has a Teams license that includes external collaboration.
Why it's wrong here
All Teams licenses that include chat functionality support external access. There is no specific license requirement for external collaboration beyond the standard Teams license. The issue is more likely a configuration on one side or the other, not licensing.
- ✗
Check if the user is a member of a team that has guest access enabled.
Why it's wrong here
Guest access is for adding external users as guests to a team, which is different from external access for chats. The scenario is about starting a chat with an external user, not adding them as a guest. Guest access settings do not affect one-to-one chats with external users.
- ✓
Verify that the external user's organization has allowed external access to your domain.
Why this is correct
External access is a two-way setting. Even if your organization allows the external domain, the external organization must also allow your domain for communication to work. If the external user's organization has not allowed your domain, they cannot receive or start chats. This is a common oversight.
- ✗
Ensure the user is assigned a Teams messaging policy that allows external chat.
Why it's wrong here
Teams messaging policies control features like chat, but external chat is governed by external access settings, not messaging policies. Messaging policies control things like read receipts, translation, and chat permissions, but not whether external users can be contacted. Therefore, this is not the correct check.
