Office 365 Synchronization fails with the following error:

"An item with the same key has already been added"

In CCPv2 users like and appear as duplicates.

O365 Endpoint database contains duplicate entries with the same UserObjectId in User table:

PrincipalName   FirstName       LastName        DisplayName     UserObjectId John       Doe   John Doe CCDEF871-E714-48A7-945C-B08802FB69C5      John  Doe   John Doe    CCDEF871-E714-48A7-945C-B08802FB69C5


In certain scenarios, same user could be added to OA with prefix and without it. Such situation is prevented, starting from O365 APS application version 16.8.6. The issue is registered with internal ID APSA-18040.
