Can we restrict sending mail to O365 group mailbox to only group owners?
We want only group owners should able to send email to respective O365 group mailbox. Other members of the group can only read the mails.
If that's what you want, Groups are not the feature you should be using. Sure, you can restrict sending via PowerShell and the corresponding parameters:
AcceptMessagesOnlyFrom
AcceptMessagesOnlyFromDLMembers
AcceptMessagesOnlyFromSendersOrMembers
RejectMessagesFrom
RejectMessagesFromDLMembers
RejectMessagesFromSendersOrMembers
RequireSenderAuthenticationEnabled
However, even if you apply this to members, they can still create items via OWA or Outlook, and perform any other operations.
VasilMichevthanks for the explanation and workaround! what feature would you rather recommend to being able to restrict users to send emails to all members?
