Currently when we use the People Picker Web Part, some users just cannot be found. What could be the cause, and where do we start investigating?

  • are you talking about default OOUT People web part? May 12, 2023 at 12:55
  • Yes the OOTB one May 13, 2023 at 8:11
  • What type of users aren't appearing members or guest accounts? May 13, 2023 at 16:03
  • @CallumCrowley Members. But some members do appear though. Very weird. May 15, 2023 at 1:27
