I have a Sharepoint list with a few "People" columns. I cannot select specific people for these columns, even though the user pops up when I begin typing and I select the user. Some people work just fine, but others simple reject the input when I click "Save." PowerAutomate pulls the full profile by the same upn, but when I try Create an Item with that same upn in PowerAutomate, the List connector returns, "
"The specified user firstname.lastname@example.org could not be found."
Any ideas as to why this is happening?
