PowerShell to Set a Field Required in SharePoint Online List:
Here is the PowerShell to set a column as “required”
#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
#Set parameter values
$SiteURL="https://crescenttech.sharepoint.com/"
$ListName="Projects"
$FieldName="StartDate"
#Get Credentials to connect
$Cred= Get-Credential
#Setup the context
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)
#Get the List
$List = $Ctx.Web.lists.GetByTitle($ListName)
#Get the Field
$Field = $List.Fields.GetByInternalNameOrTitle($FieldName)
$Field.Required = $True
$Field.Update()
$Ctx.ExecuteQuery()
Write-host "Field 'Required' Settings Updated!"
This makes the field required in SharePoint. Similarly, To remove required field setting for multiple fields in SharePoint list, use:
#Set parameter values
$SiteURL="https://crescenttech.sharepoint.com/"
$ListName="Projects"
#Set Field Internal Names to make required or disable required
[email protected]("StartDate","ProjectID","Category","Budget")
#Get Credentials to connect
$Cred= Get-Credential
#Setup the context
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)
#Get the List
$List = $Ctx.Web.lists.GetByTitle($ListName)
#Iterate through each field given
ForEach($FieldName in $FieldNames)
{
#Get the Field
$Field = $List.Fields.GetByInternalNameOrTitle($FieldName)
#disable "required" setting for the field
$Field.Required = $False
$Field.Update()
$Ctx.ExecuteQuery()
Write-host "Field '$FieldName' Required Settings Updated!"
}
PnP PowerShell to Set a List Column Required in SharePoint Online
#Config Variables
$SiteURL = "https://crescenttech.sharepoint.com"
$ListName = "Team Projects"
$FieldName= "ProjectStatuss" #Internal Name
#Get Credentials to connect
$Cred = Get-Credential
Try {
#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -Credentials $Cred
#Get the Field from List
$Field = Get-PnPField -List $ListName -Identity $FieldName -ErrorAction Stop
#Set the Field Required
$Field.Required = $True
$Field.Update()

}
catch {
write-host "Error: $($_.Exception.Message)" -foregroundcolor Red
}

Get-PnPField -List $ListName | Where { $_.Required -eq $True -and $_.Title -ne "Name" -and $_.ReadOnlyField -eq $false -and $_.Hidden -eq $false -and $_.InternalName -ne "ContentType" -and $_.InternalName -ne "Attachments"} | Set-PnPField -Values @{Required=$False}

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
#Set Variables
$SiteURL="http://intranet.crescent.com"
$ListName="Projects"
$FieldName="StartDate"
#Get Web, List and Field Objects
$Web = Get-SPWeb $SiteURL
$List = $Web.Lists[$ListName]
$Field = $List.Fields[$FieldName]
#Set Required to False
$Field.Required = $False
$Field.Update()
Write-host "Field Required Setting updated!"
This removes required field in SharePoint list (makes the field as non-mandatory).
