I have run get-dynamicdistributiongroup cmdlet to get all DDL exist in my environment. I found some of them have value in ExternalDirectoryObjectId attribute and some of them don't have value. I have searched over online and found that ExternalDirectoryObjectId make relation between Azure AD directory Objects' ObjectId attribute. I have taken one DDL which contains ExternalDirectoryObjectId attribute and searched that object using get-azureadgroup -ObjectId <value>. But I got "Resource_not_found" error. I have two questions.
- In what case, ExternalDirectoryObjectId present in DDL?
- If ExternalDirectoryObjectId make relation with Azure AD, why am i unable to find that group in Azure AD?
Kindly advice me for above queries. Please correct me if understand wrongly.
