You can add these permissions using one of the following methods:

• Using the admin center (SharePoint Online 2010 and 2013)

  SharePoint Online admin center allows granting owner permissions for only one personal site collection at a time, which means this procedure has to be done for every personal site collection.

• Using a PowerShell script (SharePoint Online 2013 only)

  A PowerShell script using SharePoint Online cmdlets is available to facilitate the task of granting owner permissions to a specific account for all personal site collections.

To add the Owner permission using SharePoint Online admin center

1. Access SharePoint Online administration center (https://your_domain-admin.sharepoint.com).

2. In the navigation panel on the left, click user profiles.

3. Click Manage User Profiles.

4. Use the search box to find the user profiles of the users you want to crawl.

5. Right-click an Account Name and then select Manage site collection owners.

   

6. Add the crawling account to the list of Site Collection Administrators.

   

7. Click OK.

To grant the Owner permission using SharePoint Online Management Shell

1. Install SharePoint Online management shell (see the Microsoft document Set up the SharePoint Online Management Shell Windows PowerShell environment).

2. Download the zipped COVEOSPO.PS1 script file to the server where the SharePoint Online management shell was previously installed.

   Important: The script was updated on January 21, 2016.

3. Unzip the file.

4. On the Windows menu select Start > All Programs > SharePoint Online Management Shell.

5. Load the COVEOSPO.ps1 script.

   Example: $> . C:\script\COVEOSPO.ps1

6. Run the Set-COVEOSPOMySitesOwner and Set-COVEOSPOSitesAdmin cmdlets.

   The following table lists the parameters supported by each of the cmdlets:

   Parameter and definition	Set-COVEOSPOMySitesOwner	Set-COVEOSPOSitesAdmin
   AdminSiteUrl Specifies the URL of the SharePoint Online tenant.	✓	✓
   AdminUsername Specifies the username of the SharePoint Online global administrator used to connect to the SharePoint server. This user will be added to the sites collection administrators (for the Set-COVEOSPOMySitesOwner cmdlet) or the personal sites administrators (for the Set-COVEOSPOSitesAdmin cmdlet) if the NewAdminUsername parameter is empty.	✓	✓
   AdminPassword Specifies the password of the SharePoint Online global administrator used to connect to the SharePoint server.	✓	✓
   UsersDomainName Specifies the domain of the users from which to retrieve personal sites.	✓
   NewAdminUsername Specifies the username of one or more SharePoint Online users and/or group(s) to be added in the sites collection administrators (for the Set-COVEOSPOMySitesOwner cmdlet) or the personal sites administrators (for the Set-COVEOSPOSitesAdmin cmdlet). If not set, the user specified in the AdminUsername parameter will be added. Notes: You can add user and group at the same time by separating values with comma. Example: -NewAdminUsername "user1@domain.com","user2@domain.com","c:0-.f|rolemanager|s-[accountNumber]" You must find the group ID to add the associated users in the sites collection or personal sites administrators (see To find a SharePoint group ID).	✓	✓
   Remove This parameter is a switch that, when included in the script, removes the user(s) and/or group(s) specified in the NewAdminUsername parameter (instead of adding them) from the sites collection administrators (for the Set-COVEOSPOMySitesOwner cmdlet) or the personal sites administrators (for the Set-COVEOSPOSitesAdmin cmdlet).	✓	✓

   Examples:

   • $> Set-COVEOSPOMySitesOwner -AdminSiteUrl https://acme-admin.sharepoint.com -AdminUsername admin@acme.onmicrosoft.com -AdminPassword password -UsersDomainName acme.onmicrosoft.com

   • $> Set-COVEOSPOSitesAdmin -AdminSiteUrl https://acme-admin.sharepoint.com -AdminUsername globaladmin@acme.onmicrosoft.com -AdminPassword password -NewAdminUsername "user@acme.onmicrosoft.com", "c:0-.f|rolemanager|s-1-5-21-2644810858-3409521387-2709630237-4818302"
