Applies To: Centrify for SaaS/Office 365


Office 365 provisioning is failing for objects. The synchronization report shows that the reason is due to an O365Coexistence. 

Here is an example of the error:

Users failed: =>
Reason: Operation failed on object using O365Coexistence. AdministrativeServiceErrorCode: AttributeValueMustBeUnique Unable to update this object because the following attributes associated with this object have values that may already be associated with another object in your local directory services:



Correct or remove the duplicate values in your local directory. Please refer to for more information on identifying objects with duplicate attribute values. 


This issue occurs due to a duplicate entry of the UserPrincipalName or email aliases for the object in question. To resolve this issue, determine duplicate values and values that conflict with other AD directory synchronization objects by using one of the following methods. 

  • Method 1:
  • Method 2:
  • Method 3:
    • Determine attribute conflicts that are caused by objects that weren't created in Azure AD through directory synchronization. To do this, see the following Microsoft Knowledge Base article: 
  • Method 4:
    • Perform the following command using the Windows Azure Active Directory Module for Windows Powershell, then clean up the duplicated entries of the problematic objects: 
    • Get-MsolUser -All | where-object { $_.proxyaddresses -like ""} | FL
