Remove AD distribution group sync and manage through O365

Kaue Mendes | KLA 20 Reputation points

Good afternoon,

Today my distribution groups are being managed by my AD, but we don't have more access to the EC and at the time of creation I can't configure it to not receive external email in this group, I didn't find this option within the AD.

I would like to remove local synchronization to manage only in the cloud these already created groups

    Hi @Kaue Mendes | KLA ,

    Thanks for posting in our Q&A forum.

    For the hybrid environment, we can synchronize distribution groups to the cloud with AAD. In this case, however, these groups need to be managed from on-premises.

    If you want to manage these groups only from O365, you have to re-create distribution groups in the cloud manually. Then add the membership, x500 addresses, then remove the on-premises groups. You can check these blogs for more details:
    Migrate Distribution Groups from Exchange On-Premise to Exchange Online,
    Migrating Distribution Groups to Office 365.
