New Users Unable to Send or Receive Messages in Microsoft Teams

Question

Hello,

We are encountering an issue in our organization where new users are unable to send or receive messages in Microsoft Teams. Despite having Microsoft 365 E5 licenses, the users cannot communicate within Teams or with other internal users.

Troubleshooting Steps Taken:

Verified that the users have the correct Teams license assigned.

Ensured Teams functionality is enabled for these users.

Checked Messaging Policies and ensured they allow chat.

Tried signing in/out and clearing cache for the users.

Tested with multiple devices and web client.

However, the issue persists. Has anyone else faced something similar? Any guidance would be greatly appreciated!

Thank you in advance!

Hello, you just need to go Role-based chat permissions and toggle off that

Here are a few ideas and advanced troubleshooting steps that might help pinpoint why new users are unable to send or receive messages in Teams despite having appropriate licensing:

1. Verify full account provisioning:

 • Confirm that the user objects in Azure Active Directory have fully synchronized and that there aren’t any provisioning delays or errors in Office 365.

 • In some cases, it can take a little longer for all backend services (including Teams) to fully enable a brand-new account.

2. Check Teams-specific settings in the Teams Admin Center:

 • Although you’ve verified that Teams is enabled and messaging policies allow chat, double-check that these users are in the correct policy groups and that no scoped or conditional policy might be inadvertently blocking messaging for new users.

 • Review the “Org-wide settings” under Messaging to ensure that “Chat” is enabled across the board.

3. Validate the assignment of licenses beyond just Teams:

 • Even though they have Microsoft 365 E5 licenses (which include Teams), sometimes a service like Teams might not be active if other dependent services (like Exchange Online for calendaring, or proper Skype for Business service settings) aren’t configured properly.

 • Confirm that the service plan details in the license (via PowerShell or the admin portal) reflect that Teams is active for these users.

4. Check Conditional Access and Security Policies:

 • Sometimes Conditional Access policies (or other security controls) can affect new user accounts differently. Ensure that any network, device, or session-based policies aren’t inadvertently blocking Teams communication.

 • If you’re using any third-party security or compliance tools, temporarily verify that they’re not interfering with chat functionality.
