SP2016 Powershell: Error Updating OwnerAlias - InvalidData

Question

I'm trying to update a site collection's owner and secondary with PowerShell. Currently, they're blank and CA fails. I enter the following in PowerShell:

Get-SPSite "http://company/division/site" | %{Set-SPSite $_ -OwnerAlias "spadmin" -SecondaryOwnerAlias "altspadmin"}

The following error is returned:

Set-SPSite : At line:11 char:46
+ Get-SPSite "http://company/division/site" | %{Set-SPSite $_ -OwnerAlias "spadmin ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidData: (Microsoft.Share...SPCmdletSetSite:SPCmdletSetSite) [Set-SPSite], SPException
+ FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletSetSite

(The highlight is under the Set-SPSite command.) The names are valid. Even the domain\name fails.

Note: I don't know if this has something to do with the error, but I notice that the content db is missing the SPDataAccess and SPReadOnly. Do you know how to get these roles installed?

Answer 1

• Make sure that you have set the correct Site Collection URL at Get-SPSite "<SiteCollection>"

  • I tried this on my side and get the same error but you looks like not copy the full error message

So run first Get-SPSite to can get the Site Collection list, then add the correct site collection URL in your Cmdlet

• Make sure that the Owner Alias user is formatted as <domain>\<username>

Change site collection administrator CMDLET

Set-SPSite -Identity "<SiteCollection>" -SecondaryOwnerAlias "<User>"

Note: <User> is the name of the user whom you want to add in the format <domain>\<username>.
