Cannot delete an Exchange Online contact

KRIEGEL Kevin 0 Reputation points


we tried to delete a contact on our Exchange Online tenant but we have error message below :

Microsoft.Exchange.Configuration.DualWrite.LocStrings.UnableToWriteToAadException|An Azure Active Directory call was made to keep object in sync between Azure Active Directory and Exchange Online. However, it failed

This contact is not synchronized from our local AD or through Azure AD Connect

If I search this contact on MSOL, I cannot find it

I tried also to delete using Graph API but I have same error

How can I solve this issue ?

Thank you

    Looks like it might have been orphaned, best open a support case.
