Hello,
I have the following scenarion:
- Office 365 Exchange Online
- Local Active Directory
- Azure AD Sync
- No local Exchange Server
There is a local Distribution Group created in AD UC (Active Directory Users and Computers) and was synced to Office 365. Now this Distribution Group must set to disallow incoming E-Mails from external Persons. Because this Group was synced form Azure AD Sync to Office 365 I am not able to set this configuration in Exchange Online.
How can I set this Option now? I don´t want to install an Exchange Server onpremises to achieve my goal. Can I set this Option in any other way in my local Active Directory (AD Attribut or something else?).
Thanks for your support and best regards
Thorsten
