Find and Report on Existing Delve Blogs

With the announcement that Delve blogs will be retiring you may want to see what blogs exist in your tenant. Delve blogs create their own site collection but do not show up in the admin center or when you use the SharePoint PowerShell module and the Get-SPOSite cmdlet. Thankfully PnP Powershell does return this. I put together a PowerShell script to find blogs and put a report together including the number of posts.

First, install PnP PowerShell if you haven’t already. I recommend installing via the PowerShell gallery with the command:

  • Install-Module SharePointPnPPowerShellOnline

Here is a script to find and export the blog information using PnP Powershell. Ensure you fill in your own variables for your tenant and the file path.

try {

    #variables -> enter your own domain and output path
    $creds = Get-Credential
    $tenantadmin = "https://domain-admin.sharepoint.com"
    $outputfilepath = "c:\temp\delveblogexport.csv"

    #connect to tenant to get blog sites
    Connect-PnPOnline $tenantadmin -Credentials $creds
    $sites = Get-PnPTenantSite -Template POINTPUBLISHINGPERSONAL#0

    $resultsarray = @()

    #loop through sites to get details for blog
    foreach($s in $sites){
        Connect-PnPOnline $s.Url -Credentials $creds
        $list = Get-PnPList -Identity "Pages"
        $pagecount = $list.ItemCount
        $listlastmodified = $list.LastItemUserModifiedDate
        $contributor = Get-PnPGroupMembers -Identity "Contributors" | select Email

        #add to export object
        $obj = New-Object PSObject
        Add-Member -InputObject $obj -MemberType NoteProperty -Name DelveBlogUrl -Value $s.Url
        Add-Member -InputObject $obj -MemberType NoteProperty -Name BlogPageCount -Value $pagecount
        Add-Member -InputObject $obj -MemberType NoteProperty -Name LastModified -Value $listlastmodified
        Add-Member -InputObject $obj -MemberType NoteProperty -Name Email -Value $contributor.Email

        $resultsarray += $obj
        $obj = $null

        Disconnect-PnPOnline

    }
    #export results
    $resultsarray | Export-Csv -Path $outputfilepath -NoTypeInformation
    Write-Host "Complete" -ForegroundColor Green
}
catch
{
    Write-Host $_.Exception.Message -ForegroundColor Red
}

The results will include the URL of the site, the page count, last modified, and the email of the blog site owner.

If you want other details per page you can go directly to the pages library to view by applying “pPg/Forms/AllItems.aspx” to the blog site url. As an example:

When you go to the pages library you can download the posts. They exist in a JSON blob. This may be a good way to extract blog posts before they are removed via Microsoft.

To view the posts you will still go through “portals/hub/personal/drew” path vs “portals/personal/drew”.


Another path to get some of this information is through the User Profiles that exist. Each user profile includes a link to their Delve blog. So if you get all existing user profiles you can find where that value is filled in. The best way to get this at scale is through SharePoint search. I put together a script to do this as well. I included batching logic on the results which will be needed in large tenants as the max search results is only 500.

try
{
    #variables -> enter your own domain and output path
    $creds = Get-Credential
    $tenantadmin = "https://domain-admin.sharepoint.com"
    $outputfilepath = "c:\temp\delvebloguserprofileexport.csv"
    $returnproperties = @("PreferredName","AccountName","WorkEmail")
    $sourceid = "B09A7990-05EA-4AF9-81EF-EDFAB16C4E31"  #this is consistent across tenants
    $maxresults = 100
    $startrow = 0

    #connect to tenant to search
    Connect-PnPOnline $tenantadmin -Credentials $creds

    $resultsarray = @()
    Do{
   
        #perform search query
        $results = Submit-PnPSearchQuery -Query "*" -SourceId $sourceid -SelectProperties $returnproperties -StartRow $startrow -MaxResults $maxresults -SortList @{LastModifiedTime="Descending"} 
        $rowcount = $results.RowCount

        #loop through results in row
        foreach($res in $results.ResultRows){

            #get user profile properties
            $props = Get-PnPUserProfileProperty -Account $res.AccountName

            #check if blog site exists
            if($props.UserProfileProperties.'SPS-PointPublishingUrl' -ne ""){

                #add to export object
                $obj = New-Object PSObject
                Add-Member -InputObject $obj -MemberType NoteProperty -Name DelveBlogUrl -Value $props.UserProfileProperties.'SPS-PointPublishingUrl'
                Add-Member -InputObject $obj -MemberType NoteProperty -Name WorkEmail -Value $props.UserProfileProperties.WorkEmail
                $resultsarray += $obj
                $obj = $null
            }
        }
        $startrow = $startrow + $rowcount + 1
    }
    while ($rowcount -ne 0)
    
    #export results
    $resultsarray | Export-Csv -Path $outputfilepath -NoTypeInformation
    Write-Host "Finished" -ForegroundColor Green
}
catch
{
    Write-Host $_.Exception.Message -ForegroundColor Red
}

This is not the most efficient way to get this information but it could be helpful to double check the SharePoint sites approach. This is also a handy way to loop through user profiles via search.

Removing Permissions for Viewing Modern Personal Blogs in Office 365

A personal blog can be a great tool for you to contribute your thoughts and ideas. Office 365 provides the capability for everyone to have a personal blog that can be accessed via your profile page. 

When you create a new blog post this will be automatically be view-able by all employees. If you do not want to have this capability or manage this in any way it can be done via PowerShell. The example I put together will remove viewers access from all existing blogs so they can only be seen by the owner.

To get started we need a high level understanding of what these blogs are and how they work. I won’t go into all of the details of this because Benjamin Niaulin has already put it together in this great post:

The highlights to support this post are:

  • When a user follows the links to create a new blog post a new site collection is built with the managed path of /portals/personal with a site name of your user account
    • i.e. tenant.sharepoint.com/portals/personal/dmadelung
    • These are not viewable in any SP Admin center and Get-SPOSite will not work
  • Site collections are only built after a user initiates the creation so not all users will have one
  • Blog posts (stories) are creates at pages in the pages library on your site collection
  • Permissions are handled with SharePoint permissions and inherited down with a Contributors, Creators, and Viewers SharePoint Group
    • The viewers group includes “Everyone except external users” by default
  • The blogs are NOT deleted when a user leaves like their OneDrive site collection

And here are details the details from Microsoft around personal blog posts in Office 365:

Removing existing permissions via PowerShell

As this is all hosted in SharePoint there could be multiple ways that we can control these. Unfortunately I couldn’t find a way to control things as scale but there is a small UserVoice submission for it. What I wanted to ensure was that creators could still get to their content but no one else could view anything. The path I took to manage these was through PowerShell and CSOM (Client Side Object Model)

Here is link to the GitHub repo and I will break it down below along with the script.

Here are some key things to note:

  • I can not confirm that doing this is the best practice but it was the easiest way I found to control these without a any administrator controls available to us. 
  • This is currently built to run on demand but could be updated to run on a schedule via something like Azure Automation.
    • To catch everything it will need to run on a schedule because any future sites will not be caught.
  • This could be updated to be used as a reporting tool or identification tool for cleanup.
  • I would comment out the actual removal of the permissions and put some logging in to test before fully running.
    • Also if you have any changes please update the repo!
  • This queries the user profile service in SharePoint Online to get the full list of users which could be huge.
    • I didn’t test this on a very large environment so this could take awhile to run or need to be enhanced for scale.
  • All of the user profile gathering was copied from this post from Microsoft on how to display a list of OneDrive for Business site collections

To get started with CSOM & PowerShell with SharePoint Online here is a good blog post from Chris O’Brien. You can get the latest version of SharePoint Online CSOM here. If you download the nuget file you can change the file extension to .zip and extract the .dlls.

To utilize the script make sure you fill out the appropriate variables and more information about what this will do is below the script. Make sure you test any script you get online before you really run it!

# Use this script to remove viewer permissions from all user delve blogs that have been created
# A user will still be able to view their existing blogs and create blogs but people will not be able to see them
# This would allow you to choose in the future if you want to make them live
# 
# This could be updated to run on a schedule as this will not remove any new blogs that are created

    #And now we check the next profile the same way...

}

#Loop through all identified sites to remove blog viewers

    #Connect to blog site collection
    $ctx = New-Object Microsoft.SharePoint.Client.ClientContext($siteurl)
    $ctx.Credentials = $Creds
 
    #Connect to web and get site groups
    $web = $ctx.Web
    $groups = $ctx.Web.SiteGroups
    $ctx.Load($web)
    $ctx.Load($groups)
    $ctx.ExecuteQuery()
    
    #Get the viewers group
    $group = $groups | where { $_.Title -eq "Viewers"}
    if($group){
        #Get the users in the viewers group
        $users = $group.Users
        $ctx.Load($users)
        $ctx.ExecuteQuery()

        #Remove all users from the viewers group
        foreach($u in $users){
            $group.Users.RemoveByLoginName($u.LoginName)
            $web.Update()
            $ctx.ExecuteQuery()
        }
    }
}

The end result will be that all existing blog sites will have anyone in the Viewers SharePoint Group removed
