We have a several lists within a SharePoint site that uses the "Assigned To" field. This field has settings of type:"Person or Group", no unique values, allows multiple selections, People Only, and the"Choose From" field is set to a SharePoint group with four members in the group. The "Show field" field is set to "Name(with presence)".
Originally, when editing the form and adding "Assigned To" users, the people picker was able to resolve users when beginning to enter their names. Perfect. Following the December 2016 CU, we edit the form it can no longer resolve names from that
Group.
If we set the "Choose from" field within the column settings to "All Users", the form is able to then resolve names correctly as it searches all AD accounts/AD groups. Switching it back to a SharePoint group then causes the issue again.
I've found that the only way around it was to go to that specific group, remove the user account and then re-add the account. After doing this, the account now resolve and populates when beginning to type the name into the Assigned To field. Though, this only
resolves for that one user account. Other account that have not yet been removed and added still have the issue.
I'm wondering if anyone has ever ran into this and if there is a PowerShell script of sorts to re-sync user accounts within the permission group.
Any help would be appreciated. Thanks!
