Receiving external meetings and messages with Outlook Group
Hello all - can somebody please help me understand if https://support.microsoft.com/en-us/office/get-started-with-microsoft-365-groups-in-outlook-b86c141b-39cf-49d9-a4db-124c3d786204#ID0EBJ=Plan_Even...
Office 365 Groups (and "traditional" distribution groups for that matter), do not accept external messages by default. You can configure this via the admin center ("Allow external senders to email this group") or PowerShell:
Set-UnifiedGroup blabla -RequireSenderAuthenticationEnabled $false
Set-UnifiedGroup blabla -RequireSenderAuthenticationEnabled $false
- Actually, let's do it the easy way - I forgot you can toggle this from within Outlook/OWA too. Simply open the Group settings and toggle the "Let people outside of the organization email the group" checkbox therein.
