Hi @Anh Ho Le Bao ，
Just checking in to see how things are going with this issue. Are you able to configure the delivery management settings for the group now?

I seem to be able to reproduce the issue, looks like something broke in the EAC. As a workaround, you can perform the changes via PowerShell:
Set-UnifiedGroup groupname -AcceptMessagesOnlyFromSendersOrMembers @{add="user@domain.com"}
I will ping few folks to take a look at the portal issue...

Hi @Anh Ho Le Bao ，
Noticed that there's a relevant active issue(EX718672) which is being worked on and the current workaround is to utilize PowerShell to replicate the functionality:

Hi @Yuki Sun-MSFT I have been having the same issue @Anh Ho Le Bao have since yesterday, and I can confirm this is NOT yet resolved. I have Exchange Admin and User Admin activated and the same error is still happening.
Should I use the PowerShell command mentioned by @Vasil Michev to add the user instead or should I wait for Microsoft to troubleshoot it?
Thanking you in advance,
Vinicius.
Hi @Vinicius Monteiro ，
If you are still affected by this issue, I'd recommend running the PowerShell command as mentioned by Vasil at this point of time so that you could be able to accomplish your management task now.
Then you may consider waiting for some more time like 1 or 2 days and see if the issue can disappear on your end. In case the error continues by then, open a support ticket via your M365 admin center to involve engineering team to help look into it further.
