Inheritance of Sharing Settings in Channel Associated SharePoint Sites

Inheritance of Sharing Settings in Channel Associated SharePoint Sites

Channel associated SharePoint sites inherit the external and default sharing settings of the parent team except when the parent team default sharing link is set to “People with Existing Access” only during creation.

The two sections highlight the testing I have done by first updating the parent team sharing setting before creating a private or shared channel which creates the corresponding site in the background.

External Sharing

Default Sharing Link type

Default link permission

Default Sharing Link type

Update of sharing settings

Whenever the parent team sharing settings are updated, the channel site sharing settings are not subsequently updated.

PowerShell script to update default sharing link type and roles for channel sites

param (
    [Parameter(Mandatory = $true)]
    [string] $domain = "reshmeeauckloo",
    [Parameter(Mandatory = $true)]
    [string] $teamName = "Company311"
)

$adminSiteURL = "https://$domain-Admin.SharePoint.com"
Connect-PnPOnline -Url $adminSiteURL

$team = Get-PnPTeamsTeam -Identity  $teamName

$m365GroupId = $team.GroupId

Get-PnPTenantSite | Where-Object { $_.Template -eq 'TEAMCHANNEL#1' -and $_.RelatedGroupId -eq $m365GroupId  } | ForEach-Object{
    $site = $_
    $siteUrl = $site.Url
    $siteTemplate = $site.Template
    $siteTitle = $site.Title
    Connect-PnPOnline -Url $siteUrl

    Set-pnptenantsite -url $siteUrl -DefaultShareLinkRole View   -DefaultLinkToExistingAccess $true  View -DefaultLinkType View -DefaultSharingLinkType View -DefaultLinkPermission
    Write-Output "Url: $siteUrl, Template: $siteTemplate, Title: $siteTitle"
}

Conclusion

Whenever a channel site is created , don’t just assume all sharing settings are inherited as in the case of the specific ‘People with existing access’ does not get updated correctly. Furthermore if parent team has unticked Same as organization-level setting the default setting may be set to the permissive setting allowed within the tenant. Subsequent tenant level updates of the default sharing settings won’t apply.
