Question

Teams issue

Vishnu Anand 280

We have two users facing issues with Microsoft Teams. Both users are added to Azure AD (cloud-only) and are on the same policies and setup.

User 1: is experiencing an issue where attachment previews are not available in Teams, and the microphone permissions are blocked due to privacy settings.
User 2: is facing login issues — the user keeps getting logged out of the Teams desktop app and is unable to log back in. The browser version of Teams works fine for both users.

Both users have the same configuration and policies applied. what might be causing these issues or steps to resolve them would be appreciated.

Hi @Vishnu Anand

Thank you for reaching out to Microsoft Q&A Forum and sharing the details regarding the Teams issues affecting the two users.

To better assist you, could you please confirm whether User 1 was added to Azure AD as an internal user or as a guest user?

In the meantime, I recommend trying the following steps for both users:

Clear the Teams cache.
Repair the Teams app using Microsoft’s official guide here: Repair apps and programs in Windows - Microsoft Support

If the issue persists, it would be helpful if you could provide:

A screenshot showing the “attachment previews are not available in Teams” message.
A screenshot of the microphone permissions being blocked due to privacy settings.
And for User 2, a screenshot of the error or behavior observed when they are logged out of the Teams desktop app.

Please note if you do share a screenshot, make sure to blur or cover any sensitive or personal information before sending it.

I look forward to hearing from you, and happy to assist further if needed.

The second issue is that the user account is visible, but it's not allowing access to the Teams interface.

@Dora-T , Yes, they have been added as internal users. We have already tested the suggested steps, but they did not resolve the issue.

Hi @Vishnu Anand

Thank you for your reply.

I really appreciate all the steps you’ve tried so far. I know it can be frustrating when things work fine in the browser but not in the desktop app.

As a moderator, I’m here to help guide discussions and share insights based on public documentation and community knowledge. However, I don’t have access to internal tools or tenant-specific diagnostics, so there are limitations to how deeply I can investigate issues like this.

For that reason, I recommend raising a support ticket via the Microsoft 365 admin center. Their team can take a closer look at your tenant and provide more targeted assistance.

You can find detailed guidance on how to open a support ticket here:

Get support - Microsoft 365 admin | Microsoft Learn

Please note: You’ll need admin permissions to raise a support request. If you’re not a Microsoft 365 admin, this article might help: How do I find my Microsoft 365 admin? - Microsoft Support

Thank you again for your patience. If you have any other questions or need help with anything else, feel free to reach out. I’m happy to help!
