Applying SharePoint Sharing Policy Settings to All of Your Teams

If you find the “Anyone” sharing setting greyed out and not matching the policy, this is how to apply SharePoint sharing policy settings to all your Team sites.

After changing the setting in the SharePoint Admin Center to allow anonymous links, you may find the option is still greyed out when sharing from Teams. This is because the policy only specifies what permissions are available — it doesn’t actually apply them to existing sites.

The solution is to use PowerShell to apply the setting to all sites.

Connect to SharePoint Online

$sharepointadmin = "https://tenant-admin.sharepoint.com"

try { 
    $var = Get-SPOGeoStorageQuota
} catch {
    Write-Host "Not connected, authenticate in other window"
    Connect-SPOService -Url $sharepointadmin
}

Check Current Settings

Get-SPOSite -Limit All | Where-Object {$_.Template -eq "GROUP#0"} | Format-Table Url, Template, SharingCapability

Apply the Setting

Get-SPOSite -Limit All | Where-Object {$_.Template -eq "GROUP#0" -AND $_.SharingCapability -ne "ExternalUserAndGuestSharing"} | Set-SPOSite -SharingCapability ExternalUserAndGuestSharing

SharingCapability values:

• ExternalUserAndGuestSharing — allow sharing with all external users and anonymous access links
• ExternalUserSharingOnly — allow sharing with authenticated external users only
• ExistingExternalUserSharingOnly — only share with existing external users
• Disabled — no external sharing

Unfortunately, you’ll still need to do this for every new Team, but at least it’s easier now!
