Why can't I post pictures on my Teams channel all of a sudden?

Hello @Nicolle,  

To understand your situation correctly, could you confirm this point:

1. Is this issue happening only on your iPhone, or does it also occur when you try on Teams Web or the desktop app?
2. For the pictures that appear blank on your phone, can you see them correctly on a computer?
3. Since you mentioned using an iPhone 15, have you checked that both the Teams app and your iPhone are running the latest versions?
4. Apart from clearing the cache, have you tried uninstalling Teams completely and reinstalling it from the App Store?

If the issue only occurs on your iPhone even after updating to the latest version and this is a work account managed by your organization, I strongly recommend you contact your IT admin to take the following steps:  

1.Report the issue through the Microsoft 365 admin center:   

When multiple tenants report the same problem, it helps the development team investigate. If it’s confirmed as an incident, it will be published in the Service Health dashboard.   

 2.Your IT admin also helps you raise a support ticket to reach out to higher technical: 

• They can go to: Microsoft 365 admin center                   
• Please follow this article: Get support - Microsoft 365 admin | Microsoft Learn    
• On right bottom corner click on "Help & support"     

When the ticket is opened, a support engineer can start a remote session to investigate the issue, review the back-end settings, and optionally run a sync tool to resolve the issue.      

I hope you understand that this forum has limitations in terms of available tools and testing environments. As a forum moderator, I only can try to do research on the issue and provide guidance based on my experience.   

I truly hope you’ll be assisted soon by our dedicated technical team. And if you receive any updates or insights, please feel free to reply here.            

Looking forward to hearing from you! 

I am having this issue on the mobile app. My employees use it to post pictures and descriptions of what they have done for the day. What I did notice is that they are taking the pics with their camera app on the phone and then adding them later, does this matter? When I tested this I first cleared the cache for Teams, turned the phone off and back on. Then I could see that everything they had tried to send had an error. (Thsi could not be previolsy seen) I did try to post a pic, I could see it yesterday but now the phone/app won't show me any of the attempted posts at all. The channel is just blank.

Hello @Nicolle,  

Thank you for reaching out to the Q&A forum! 

After receiving your information, I tested this scenario in my own environment (Teams desktop app on Windows), and I was able to upload pictures successfully.  

So, to support you better, could you provide some additional information: 

1.Are you experiencing this issue on Teams web, desktop app (Windows or macOS), or mobile app (Android or iOS)? 

2.Have you tried posting pictures from a different device? If yes, does the same issue occur there? 

3.Do you receive any error message when the picture fails to post?  

If possible, please share a screenshot of what you see when the upload doesn’t work. I will help you blur or hide any personal information if needed.     

4.I noticed you tagged this under “business.” Can you confirm if your account is a work account managed by your organization? 

5.Lastly, could you let me know the Teams app version you are currently using?  Please understand that our initial response may not always resolve the issue immediately. However, with your help and more detailed information, we can work together to identify the root cause and find a solution.             

Looking forward to hearing from you.

If you are unable to post pictures in your Teams channel, it could be due to several reasons. Here are a few possibilities:

1. File Size Limitations: Ensure that the picture you are trying to upload does not exceed the maximum file size limit set by Teams.
2. Permissions Issues: Check if you have the necessary permissions to post images in that channel. Sometimes, channel settings may restrict certain users from posting files.
3. Temporary Glitches: There could be a temporary issue with Teams. Try restarting the application or checking your internet connection.
4. Ownership Issues: If the Microsoft 365 group associated with the team has lost its owner, it could lead to issues with posting files. You may need to assign a new owner to resolve this.
5. Error Messages: If you receive an error message while trying to upload, it could provide more insight into the issue. For example, if it mentions that your OneDrive isn't available, that could be a cause.

If the problem persists, consider running a self-diagnostics tool if you have admin access, or contact your IT support for further assistance.
