Hi @Sollberger, Camber ,
In Microsoft Lists, the character limit for multiline text fields is 63,999 characters by default.
It seems this is not a common issue per my test. However, we can work together to narrow down and resolve the situation. So, Please kindly provide more information below to let us work further.
1.Does this problem occur when creating a new multi-line text column in this problematic list?
2.Consider whether the "Append Changes to Existing Text" option is enabled, as this can sometimes lead to unexpected behavior when updating the column.
3.Go to List Settings > Columns > Select the problematic column and ensure the "Number of lines for editing" is set to a higher value if it's a multi-line text column.
4.Check if there are any column validation rules that limit the number of characters. Go to List Settings > Column Settings > Validation Settings to see if there are any rules.
5.Browser Cache: Sometimes, browser cache can cause unexpected behavior. Try clearing your browser cache or using a different browser to see if the issue persists.
6.Try creating a new list with similar settings and see if the issue occurs there as well.
Summary: There may be corruption in a particular list, which can happen. If, after checking all the possibilities above, it is confirmed that the problem only occurs in this particular list, then we can only try to discard the corrupted list, which we regret.
Hope the information can help you. And if there have any unclear or misunderstanding, please feel free to post back and we’ll continue to help you all the time!
