- Verify that you have the following memberships:
securityadmin fixed server role on the SQL Server instance.
db_owner fixed database role on all databases that are to be updated.
Administrators group on the server on which you are running PowerShell cmdlets.
An administrator can use the Add-SPShellAdmin cmdlet to grant permissions to use SharePoint Server 2013 cmdlets.
If you do not have permissions, contact your Setup administrator or SQL Server administrator to request permissions. For additional information about PowerShell permissions, see Permissions and Add-SPShellAdmin.

$siteurl = "<ServerName>" $mysite=new-object Microsoft.SharePoint.SPSite($siteurl) $mysite.WebApplication.WebService.CoauthoringMaxAuthors = <MaxAuthors> $mysite.WebApplication.WebService.Update()
<ServerName> with the name of the server.
<MaxAuthors> with the maximum number of authors to allow.
Save the file and add the .ps1 extension, such as SuggestedNameOfFile.ps1.
You can use a different file name, but you must save the file as an ANSI-encoded text file whose extension is .ps1.
