SharePoint: Users cannot create new subsites


Issue

First day after my vacation and I got presented with a nice situation at one of our clients. Most users trying to create new subsites would get “Sorry, this site hasn’t been shared with you” and the site would NOT get created. Troubleshooting this showed that during site provisioning the “SiteFeed” Feature would throw an exception which would roll back the site creation. The relevant lines in the ULS logs pointed towards the “Following” (Social) of the newly created site:

FollowedContent.FollowItem:Exception:Microsoft.Office.Server.UserProfiles.FollowedContentException: ItemDoesNotExist : Item does not exist.     at Microsoft.Office.Server.UserProfiles.SPS2SAppUtility.GetPersonalUrl(UserProfile& profile)     at Microsoft.Office.Server.UserProfiles.SPS2SAppExecutionContext.InitializeForProfile()     at Microsoft.Office.Server.UserProfiles.SPS2SAppExecutionContext.EnsureInitialized()     at Microsoft.Office.Server.UserProfiles.FollowedContent.FollowItem(FollowedItem item, Boolean isInternal)

Could not follow the url https://sharepoint/newsub

Leaving Monitored Scope (Event Receiver (Microsoft.Office.Server.UserProfiles, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c, Microsoft.Office.Server.UserProfiles.ContentFollowingWebEventReceiver)).

 

The newly created site could not be added to the user’s Social list on his MySite due to an Access Denied on adding the item to the list.

Cause

The MySites were recently migrated from SharePoint 2010 (classic mode) to SharePoint 2013 (claims mode). MySites work by setting the ‘owner’ as Primary Site Collection Administrator, but the conversion to claims had erased all the classic-mode Site Collection Administrators from the migrated site collections. Querying for the Site Collection Administrators would just return empty which is of course not good.

(Blank) Site Collection Administrators

Solution

I whipped up a PowerShell script that would loop all MySites and report any sites with missing or non-matching Site Collection Administrator. Toggling the ‘report only’ flag in the script will correct the situation.

asnp Microsoft.SharePoint.PowerShell -ea 0 | Out-Null cls $reportOnly = $false Write-Host "ReportOnly:" $reportOnly $mySites = Get-SPSite -Limit ALL | ? { $_.RootWeb.WebTemplate -eq "SPSPERS" } Write-Host "Found" ($mySites.Count) "MySites" $mySites | % { $s = $_ $w = $s.RootWeb $owner = $w.EnsureUser($w.Title) $primaryAdmin = $w.SiteAdministrators | Select -First 1 if ($primaryAdmin -eq $null) { Write-Host -ForegroundColor Red ($s.ServerRelativeUrl) ": no primary SC admin. Owner should be" $owner if ($reportOnly -eq $false) { $owner.IsSiteAdmin = $true $owner.Update() } } elseif ($owner.IsSiteAdmin -eq $false) { Write-Host -ForegroundColor Yellow ($s.ServerRelativeUrl) ": primary SC admin (" $primaryAdmin ") does NOT match owner (" $owner ")" if ($reportOnly -eq $false) { $owner.IsSiteAdmin = $true $owner.Update() } } else { Write-Host -ForegroundColor Green ($s.ServerRelativeUrl) ": primary SC admin (" $primaryAdmin ") matches owner (" $owner ")" } $s.Close() }

After correcting all sites should turn up green.

 All MySites corrected
