Error Uploading Customized Thumbnail on MS Stream Video

Question

Does anyone else have any issues uploading a customized thumbnail on a video?

This video has been up for quite some time now and I'd rather get this resolved than re-uploading and losing the metrics it's attained so far.

Hello Rax,

We appreciate you spent precious time doing tests and sharing the detailed information with us.

We deeply understand the issue has affected your daily work and feel very sorry about it.

Since the issue only happens in a specific video, you don't want to re-upload the video, it seems like your colleagues also encounter the same error 'custom image uploaded failed' when trying to upload customized thumbnail for the video. Considering you also tried different image formats, in this situation, it may need to check the issue from back end for further investigation.

We sincerely recommend you inform your Microsoft 365 administrator of this issue and help you create a support ticket for the issue via Microsoft 365 Admin Center.

The support team has higher permission to remotely help you and also check the issue from background. They have more resource and correct escalation channel to help you further investigate the issue. This is also the more efficient way in handling this case for you.

Thanks for your patience and understanding so far. We hope you are keeping safe and well!

Best Regards,

Tina

Hi Rena,

It does only occur in one specific video. I have tried different image formats and i am still receiving that error.

The issue still persists on my end.

Answer 4

Hi Rax,

I did a test and somehow it works expectedly by my side.

I would like to give some possible suggestions first, you can try to see whether they can help or not:

1. Change other browsers.
2. If you don’t want to re-upload it, please check whether “replace” is ok for your choice. Here’s the list about what it will keep and delete.

Meanwhile, if the suggestions cannot work, please kindly provide us information below so that we can troubleshoot further for you:

1. Does the issue only happen this specific video?
2. If you change another picture file, can it be uploaded?

Best Regards,

Rena
