Adding a rubric: There was a problem attaching this rubric. Please try again.

Hi @Daniel-Vo
Thanks for your swift reply. I'll try to answer your questions:

Was the rubric CSV originally downloaded from Teams (Download as .csv), or was it created manually/from another template?

The rubrics that I've created from september until a couple of weeks ago where based on a downloaded .csv but altered in Numbers. With succes from september until early May.

Did you edit or re-save the CSV in Excel / Google Sheets / Numbers before uploading?

Yes. But I did that also with the previous csv files.

Does the issue happen in Teams Desktop, Teams Web (browser), or both?

If you download a rubric from Teams and immediately upload it back without editing, does it still fail?

It fails again.

Does it fail for all rubric CSV files, or only specific ones (new rubrics vs older rubrics)?

All rubrics fail right now. Also very empty new tries within Teams. When I download the csv and upload it agian... it will not attach. I do see the preview though.

Are there any special characters/long text/line breaks in the rubric cells (quotes, commas, non‑English characters)?

it's not more than a sentence, maybe two. No strange characters.

Roughly how large is the rubric (e.g., number of criteria rows and performance level columns)?

About 7-10 criteria and based on 3 level colums.

Do other teachers in your tenant see the same behavior?

Yes. Other teachers have the same experience.

Dear @Matthijs Clasener,

From what you described, I understand that you’re using Teams Assignments and trying to upload/add rubrics via a .CSV file. This was working fine before, but recently you’re getting the error: “There was a problem attaching this rubric. Please try again.” You also mentioned that even older rubrics that used to work are now failing, which is definitely unexpected.

To better assist, could you please confirm following information:

Could you please help confirm the following:

• Was the rubric CSV originally downloaded from Teams (Download as .csv), or was it created manually/from another template?
• Did you edit or re-save the CSV in Excel / Google Sheets / Numbers before uploading?
• Does the issue happen in Teams Desktop, Teams Web (browser), or both?
• If you download a rubric from Teams and immediately upload it back without editing, does it still fail?
• Does it fail for all rubric CSV files, or only specific ones (new rubrics vs older rubrics)?
• Are there any special characters/long text/line breaks in the rubric cells (quotes, commas, non‑English characters)?
• Roughly how large is the rubric (e.g., number of criteria rows and performance level columns)?
• Do other teachers in your tenant see the same behavior?

In the meantime, I recommend as below:

1/ Upload a “known-good” rubric CSV that was downloaded from Teams (no edits).

Open an assignment with a rubric > open the rubric > Download as .csv.

Create a new assignment draft > Add rubric > Upload rubric > select that CSV > Next > Attach.

2/ Try in Teams web version:

Please try the same upload in Teams Web to see if the issue is client-specific.

3/ Avoid editing/resaving the CSV in Excel

If you need changes, try importing first and then edit the rubric inside Teams, because Microsoft notes this gives the best results and the CSV format can be sensitive.
