To revisit this old post, I'm still surprised that Microsoft has not expanded the filter display beyond 10,000 unique values. I have a large list of users that have been enabled for a particular application, over 25,000 unique names, and not being able to find a specific one seems like a significant challenge. What seems odd is that I do see names that are beyond the first 10,000 unique names, so I'm a little puzzled by what is supposed to be displayed here. I took the entire list, removed duplicates, separated the first 10,000 from the rest, and then found a name in the second set of 10,000 that wasn't in the first set. Then I looked for this name in the filter display, and I found it. Does anyone understand how Excel determines which values to display? Thank you!
