"Provisioning "Subscription" for APS application Office 365" task fails:

"code": 500,
"message": "GRAPH API Error: Another object with the same value for property proxyAddresses already exists.",


Two or more customer's users on the Microsoft Cloud side has equal ProxyAddresses property filled. It could be checked using the following cmdlet:

PS C:\> Get-MsolUser -TenantId 32e9e-...-bc4b9c  -UserPrincipalName | select Objectid,ProxyAddresses | fl

In case AD Synchronization feature is enabled on the MOP side for affected - this property cannot be modified manually.


Please contact the end user in order to modify the ProxyAddresses property in their local Active Directory catalog.
