Question

Desktop teams app doesnt show attachments for other users, yet web app does?

RussellGarner-9076 20

As of 31/10/25 now when I post in a channel and attach a file, the file appears for me, but doesnt appear for others in the channel using the desktop teams app. If they are using the web app then it does appear.

How can I make the atatchments appear. I've tried all the clearing cache, uninstall/reinstall, etc options
Is this a Microsoft bug?

I was waiting for someone to mention this here.

As a contractor working for an MSP, this has been a very widespread issue.

Workaround: Enable Early Access Public Preview and quit and reopen Microsoft Teams

Dear @RussellGarner-9076,

Thank you for posting your question in the Microsoft Q&A forum.  

Could you please check with other users and ask them to test on different devices (other laptops/desktops) to see if the error is occurring there as well, or if the attachment displays normally?

Currently, based on your description (attachments display normally on the Teams Web but not on the Teams App for other users), the issue lies with their Teams application, not with your Teams application or your account (since the web version works for them).

I would like to inform you that I am aware of an ongoing issue affecting access to some Microsoft 365 services and portals, which includes Teams.

Issue ID: MO1176905

Status: Service degradation

User's image

As a moderator, I do not have the ability to have a deep understanding of the technical processes of Microsoft product teams. However, I am constantly monitoring the service status page for the latest updates and will gather information on the number of affected users.

In the meantime, please try accessing the Teams app frequently and refreshing continuously. You can also use the Teams Web as a temporary workaround while you wait. Microsoft will fix this issue soon.

I sincerely hope for your understanding and patience in this situation. If there are any developments or troubleshooting instructions from Microsoft, I will check back immediately and let you know right away.

Also, please accept this answer so that others can quickly confirm that this issue is known and that Microsoft is working on it.

Looking forward to your response!

Hi Jeanie,

Thanks for your response.

We have tested this on multiple devices/accounts and can consistently trigger the issue for all staff. Web Teams app shows correctly, desktop Teams app does not.

Version of desktop Teams also doesnt seem to be relevant as we have also tested on older and latest versions of the desktop app and same issue prevails.

Dear @RussellGarner-9076,

This issue has been confirmed as an incident, and the Microsoft team is actively working on a resolution. I will keep you updated on the status as soon as there are any changes.

In the meantime, please kindly help me try using Teams Web and occasionally refresh the Teams app to maintain the best possible experience. I’ll continue to share updates whenever new information becomes available.

I truly understand how frustrating this situation can be. However, as a moderator of this forum, I’m unable to intervene directly with Microsoft products. I’ll do my best to support you within my scope, and I kindly ask for your understanding.

I’ve noticed that many other users are experiencing the same issue.

Is there an incident number or id associated with this "Microsoft confirmed" incident, so we can follow it up?

Dear @RussellGarner-9076,

I included the attachment in my first response. Let me copy it here for your convenience.

Issue ID: MO1176905

Status: Service degradation

You can reach out to the Global Admin (usually the organization's IT Admin), so they can track it in the Admin Center > Service Health, then type the issue ID to follow.

Last time I checked, the status was still service degradation.

MO1176905 isnt related to this issue...

Also I am the Global Admin of our tenant and can see the Service Health entries and nothing in there is relevant to the issue I am experiencing.

Dear @RussellGarner-9076,

Thank you for your quick response!

There is an underlying root issue, and many of the problems you’re seeing are actually impacted by this root issue. That’s why some errors may appear unrelated, but they share the same cause.

As a temporary workaround, please kindly help me try clearing the Teams cache for a few users.

If the problem persists after clearing the cache, then this is indeed a system-level incident that needs further investigation.

Microsoft is actively working on a fix, and I will keep you updated as soon as they have progress. In the meantime, after clearing the Teams cache for users, please let me know the result.

HI Jeanie,

I mentioned that in my first post, that I had already tried clearing caches, installing-reinstalling, etc, and none of that worked, so indeed a systems level incident that needs further investigation....

Dear @RussellGarner-9076,

First of all, please allow me to apologize if I may have misunderstood your point earlier.

To help Microsoft investigate this at the service level, could you please report the issue via Service Health in the Microsoft 365 admin center?

Go to Microsoft 365 admin center.

Navigate to Service health.

Click Report an issue and provide a short description.

Include details such as multiple users affected and note that all general troubleshooting steps have been tried.

If possible, please help me update before that. No rush - whenever it’s convenient for you.
