The User Does Not Exist or is Not Unique occurs in People Picker in SharePoint 2010/2013?

Hello Sharepointers,

When you are using people picker in your sharepoint project/app, if you add two or more users in the people picker. You will face this issue”The User Does Not Exist or is Not Unique”. To resolve it , we need to change the People picker field schema in the following fashion.

By Default Mult is set to false. That means, it allows one or two people field in the people picker. We need to set it to True.

<Field ID=”{}”
Name=”Users”
DisplayName=”Users”
Type=”UserMulti”
UserSelectionMode=”PeopleOnly”
Required=”TRUE”
Group=”My Site Columns”

</Field> to

<Field ID=”{}”
Name=”Users”
DisplayName=”Users”
Type=”UserMulti”
UserSelectionMode=”PeopleOnly”
Required=”TRUE”
Group=”My Site Columns”
Mult=”TRUE”>
</Field>

Happy SharePointing 🙂
