Teams Chat in Outlook returns no-license error

Question

Teams Chat in Outlook returns no-license error

Mari 10

Hello,

We are having the following issue, and hoping to get some advise on how to resolve this:

A user is unable to use the chat feature in the new Outlook at https://outlook.cloud.microsoft/. When they attempt to use it, they receive an error displayed as the following raw resource keys:

default_auth_no_license_title

default_auth_no_license_description

The same issue happens in inPrivate/incognito mode.

User licensing:

The user is assigned Microsoft 365 A5 for students use benefit, which includes Exchange Online (Plan 2).

We would like help identifying the cause of this error and how to resolve it.

Hello @Mari

As you have shared, you are trying to use the chat feature in the new Outlook at outlook.cloud.microsoft, but instead of the normal interface you are seeing text that looks like raw resource keys: “default_auth_no_license_title” and “default_auth_no_license_description

To confirm the situation and suggest the troubleshooting steps in the right direction, may I confirm a few points:

Regarding the chat feature you mentioned when accessing Outlook on the web, is this actually the “Message in Teams” option in the New Outlook?
Also, are there any other users experiencing a similar issue with Outlook on the web, or is it only happening for this specific user?

Along the way, here are a few simple steps you can try to double‑check what might be happening on your end.

1/ Verify Teams license assignment:

In the Microsoft 365 admin center, open the student’s account and confirm that the Teams service plan is listed and switched on.

Sign in as an administrator.
Go to Users > Active users.
Select the student’s account.
Under Licenses and apps, expand the assigned license (Microsoft 365 A5 for students).
Look for Microsoft Teams in the list of service plans.
Make sure the toggle for Teams is switched on.

2/ Test Teams chat directly:

Sign in to Microsoft Teams with the same account and try sending a chat message.
If chat does not work in Teams, it will not appear in Outlook either.

3/ Review education chat policies:

In the Teams admin center, check if supervised chat or restricted chat policies are applied.

These settings often control whether students can use chat in Outlook.

If the issue still remains after trying all the steps above, please share a screenshot or provide more detailed information. I will check the situation and continue to support you.

Hi Alina,

Thank you very much for your response.

Please the the answers to the points that you raised:

Regarding the chat feature you mentioned when accessing Outlook on the web, is this actually the “Message in Teams” option in the New Outlook?

Here is the feature in question:

Also, are there any other users experiencing a similar issue with Outlook on the web, or is it only happening for this specific user?

It is happening to the user who reported the issue, and we also tested with our own student account, and we ran into the exact same issue.

1/ Verify Teams license assignment:

I have verified with the student that they have no issues accessing MS Teams on the web or using the Desktop app, and they can make calls, chat, etc in a normal way. They also have a tick against this licence: Microsoft Teams (Microsoft 365 for students use benefit)

2/ Test Teams chat directly:

No issues sending a message to another user via https://teams.cloud.microsoft/

3/ Review education chat policies:

I checked the Teams messaging policies, and both Chat and Chat with groups are enabled. I apologise if you meant some other settings, and I am happy to recheck if I looked in the wrong place.

Hi

Since this issue is affecting multiple users in the organization and I understand that administrative access to the Microsoft 365 Admin Center is available, I recommend opening a support case directly with Microsoft Support. This will allow the support team to perform backend diagnostics and, if necessary, arrange a remote session with the appropriate engineering team.

Through this forum, I can only provide guidance based on the information available and help with troubleshooting. I do not have access to tenant-level diagnostic tools or the ability to investigate service-side entitlement and licensing issues directly.

Please follow the detailed steps below.

(If you are not the global admin, please kindly ask your IT Admin to do it for you)

Sign into the "Microsoft Admin Center"

After clicking on "Help & Support" button like this image, you can type "I need agent support via phone or email". After that, you can click on "Contact support"

Choose contact method: "Phone"

Fill all the information in this contact support details, please describe your situation carefully so they will have enough information to help you.

Finally, clicking on "Contact me"

After completing them, you will receive an email appointment for a meeting to review this issue professionally together.

To help expedite the investigation, I suggest providing Microsoft Support with the following summary and adding any additional details relevant to the environment:

Issue Summary

Multiple users with Microsoft 365 A5 for Students Use Benefit licenses are unable to use the Teams Chat ("Message in Teams") integration in New Outlook on the web (https://outlook.cloud.microsoft/).

When opening the chat pane, Outlook displays the following errors:

default_auth_no_license_title

default_auth_no_license_description

The issue occurs across multiple student accounts and is reproducible in both standard and InPrivate/Incognito browser sessions.

Validation Performed

Microsoft Teams licensing is assigned and enabled for affected users.

Teams web and desktop clients function normally.

Users can send and receive Teams messages successfully via https://teams.cloud.microsoft/.

Teams calling and chat features work as expected.

Teams messaging policies have been reviewed, with both Chat and Chat with Groups enabled.

The issue has been reproduced using multiple student accounts, indicating that it is not isolated to a single user.

Observation

The issue appears to be isolated to the Teams Chat integration within New Outlook on the web. Standalone Microsoft Teams functionality remains fully operational, suggesting a potential entitlement, licensing recognition, feature availability, or service-side issue affecting the Outlook-Teams integration for student accounts.

Assistance Requested

Please investigate whether there are any known issues, licensing limitations, entitlement requirements, or service-side configuration concerns affecting the Teams Chat integration in New Outlook for users licensed with Microsoft 365 A5 for Students Use Benefit.
