Modify Permission Level of Existing Security Group in SharePoint Online (Office 365)

Requirement:

During my training period, I came across to a scenario, where we need to modify the permission level of an existing security group. Initially the group’s permission Level was “Designer” level as it is shown in following figure.



And we need to modify the Group property and assign “Contribute” permission level. Set-SPOSiteGroupcmdlet allow us to address this requirement.

Syntax:

• Connect to SharePoint Online by using the following PowerShell command. It takes the URL of our tenant admin and a username. Then it will ask for password.
  

  Connect-SPOService -Url https://moharanakirti-admin.sharepoint.com [email protected]

• Modifying the SharePoint group permission level.
  

  Set-SPOSiteGroup -Site https://moharanakirti.sharepoint.com -Identity "Kirti Designers” -PermissionLevelsToRemove “Design" -PermissionLevelsToAdd "Contribute" –[email protected]

Output:

After execute the above cmdlets the Group will be having Contribute permission level as shown in following figure.
