EDIT User Permission is greyed Out sharepoint Online

[ianpokhrel]

I was trying to edit user permission for a GRP, found that its greyed out, and doesn't allow to make any changes. is it because it's a office365 GRPS, and that's how it is setup by design when site was initally setup ? what about if i don't want those GROUPS (O365 GRPS) any more, is there a way to get rid of it?

Hello,

try to select one group at a time. Also you can add new groups then edit this groups. Even in the Team sites with the Office 365 groups you can edit the permissions. But you can't downgrade the Team Site and remove the Office 365 or going back to the classic Team site.

Thanks
