I have one account in my local AD which has been synced with Azure AD cloud.
I need to add another (alias) email to it's account but got the error in ExO:
"Error executing request. An Azure Active Directory call was made to keep object in sync between Azure Active Directory and Exchange Online. However, it failed. Detailed error message: Exception happened when doing AAD dual-write.'
I have no Exchange in my local AD.
How I can add additional email addresses to synced accounts like that?
