Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi Đặng Bình Minh,
Thanks for your feedback.
According to your description, you cannot change the team picture unless you change the name of the team. Firstly, I’d like to confirm whether you are using Teams for Education or not. If so, I suggest you try the following methods and check whether it works:
1. Assign the owner role to another person, and then let that owner help you change the team picture.
2. Try again with different network connection such as WiFi.
If this issue still persists, to further assist you, I’d like to collect the following information:
1. The detailed screenshot about your issue, and I will test it from our side.
2. Please collect Debug logs and send the logs to me via private message at your convenience. I will help you check the reason. To get the logs, reproduce the issue first and then press Ctrl + Alt + Shift + 1. The debug logs are automatically downloaded to the folder: %userprofile%\Downloads.
Thanks for your patience and efforts.
Regards,
Seven
