Background:
I'm building an App that uses several Comboboxes connected to some Person or Group columns in a SharePoint List. I intend to update these to use the Office 365 Users connector eventually, but I am curious to figure out what exactly the Choices function is doing by default (i.e. "Choices[@List].PeopleColumn").
Observation:
I'm in a small org that will adopt Microsoft 365 soon, so we have a handful of user accounts set up in what is essentially a test environment, but there are so few people that delegation isn't an issue. After I was added to this organization, I started working with Power Apps to make a few basic forms; and when I made any people picker boxes, selecting those didn't bring up any names by default (but typing a name or email would bring up relevant usernames). But a few weeks ago I added another user to the organization, and now each time I select a combobox this user's name is the only one to show up by default. Hmm... It's not bad and doesn't break anything, but it's just weird. What I see when I click a box:
Testing:
I've tried a few things. When I highlight the combobox and check the values from the formula bar, the Choices([@List].PeopleColumn) shows a table with only one record containing the one user. If I type an @ or a . in the search box, it brings up the full list of people just fine. If I try to use filtering in the Choices function to show only myself (such as Choices([@List].PeopleColumn, User().FullName) to return only me), I can see that the Choices function shows a Table with my information in it before I click the combobox; but AFTER I click the combobox, it still replaces me with the other user. I'm baffled.
I tried searching through relevant username lists in various M365 admin panels to see if I could find any differences between that user and other users, but results are coming up empty. I have not yet tried adding a new licensed user because we're pretty limited on available licenses.
Inquiry:
So, out of morbid curiosity, does anyone have any insight as to where a Choices function as the Items attribute of a people picker combobox draws from to display a list of contacts? I imagine it filters the org's contact list in a weird way by default, or Choices itself is just broken. I doubt I'll get an answer to this, but I figured I'd at least try to ask a community that might know. Thanks!
