Hello everyone, I am looking for a powershell script to remove group owner permission from a public folder in exchange online.

Hi @Laxson Paradza Can you clarify what do you mean by "group owner" here? If you would like to remove all owner permission from a public folder, you can connect to Exchange Online Powershell and run the following cmdlet: Get-PublicFolderClientPermission -identity "\PublicFolder" | where{$_.AccessRights -eq "Owner"} | Remove-PublicFolderClientPermission If the answer is helpful, please click "Accept Answer" and kindly upvote it.

What i mean is e.g I have a group called: Test1 with members. This group has Owner persmission to a public folder called Folder1. There are other groups also with Owner Permission to Folder1. What i need to do is remove the group permission Test1, so that it doesn't have any permission to Folder1. I need to accomplish this by using a powershell script. I hope this is clearer now.

Thanks for the clarification.

So I suppose the groups here are mail enabled security groups.

You can try this script:

$owners = Get-PublicFolderClientPermission -identity "\PublicFolder" | where{$_.AccessRights -eq "Owner"} foreach($owner in $owners) { if((Get-Recipient $owner.user).RecipientType -eq "MailUniversalSecurityGroup") { Remove-PublicFolderClientPermission -identity "\PublicFolder" -user $owner } }
