Add O365 Group Owner to Site Collection Administration List
ChrisFicekin the new SPO admin center, select the site, then look at the info panel, if the group is disconnected from the owner role, a message box will show up with a link to reconnect it.
ChrisFicek You were right, this is a problem on this specific site.
I deleted the Owners group from site collection admins on a Test site, and then added them back up from admin center and it worked: the Owners group showed up again in site collection admins.
The site I have trouble with has been renamed indeed, so that might be why it's not working anymore... I unfortunately can't recreate it because it's already been quite challenging to get the users to this site.
I have even tried to use this trick [site address]/_layouts/15/permsetup.aspx to get my Owners group back, didn't work.
So I have created a security group with the owners names and added it as site collection admins. Do you see a big risk in the fact that the Owners group are not site collection admins anymore?
Thanks for your help

@Chris Ficek No idea what kind of bug hapened, but running the Get-SPOUser command shows that both groups (with or without _o at the end of GUID) gets the same display name of "XXX Members", whereas for other sites it shows "XXX Members" and "XXX Owners":
As you can see, the "XXX Members" group is part of SP Members and SP Owners, that's because I have tried forcing the GUID ending "_o" into the SP Owners group to see if it would at least get the right group as owner in the background, even with wrong display name, but unfortunately it picks the "XXX Members" one.
Is there a way to rename the group ending "_o" to "XXX Owners" in your mind? Or any sollution comes to your mind with this added info?
Your help is very much appreciated
Thanks

OrangeJuiceJones If above suggestions are not working for you, try using Power automate flow / REST API to add group to SCA programmatically as show in below article:

OrangeJuiceJones, its been a few years since I've encountered this issue. Have you tried going to SharePoint Admin Center > Locate the active site and select it to get to the site settings. I am curious if there is a message that is prompt to add the group owners as admins is still.
- I'm having the same issue - after renaming group, I can only add members to SCA and not the owners 😞
I've tried Powershell (Set-SPOUser) and same problem. Is there a fix? CharlotteDessertenne If you created and added another security group to the site collection admin, I think it should be fine.
ChrisFicek No problem, Chris, thanks for trying! 🙂
Maybe someone passing by will have an idea, otherwise I'll just leave the site as is with the current set up which is not ideal but does work
Thanks
CharlotteDessertenne I am not familiar in renaming the permission group name with PowerShell. Sorry, I wished I could help you there.
