You cannot reuse UPN for users in Project Online and Project Server 2013
- User John Doe is assigned the UPN and email address of JDoe@contoso.com.
- John Doe leaves the company and his Active Directory user account isn't deleted.
- JDoe@contoso.com is removed from the Active Directory group that's used to synchronize users to Project Web App.
- The UPN and email address of JDoe@contoso.com is later reassigned to user Jane Doe.
In this scenario, the Active Directory group will successfully synchronize to Project Web App. However, Jane Doe will see the historical data for John Doe in the Project Web App (PWA).
For example: John Doe is an employee at Contoso, his UPN or email is JDoe@contoso.com. His account is added to an AD group that's used to synchronize users to PWA security groups. John Doe then leaves the company, his account is deleted from the AD group, and on the next synchronization with PWA his account is marked as Inactive.
Later, a new employee by the name of Jane Doe joins the company. At Contoso they've a policy to reuse UPNs when they're available. Jane is given the UPN or email address of JDoe@contoso.com. Jane is added to an AD group that synchronizes with PWA security groups. When the sync occurs, PWA matches the UPN only. PWA sees that UPN already assigned to an inactive resource and links up the new AD user with the old PWA user which isn't the desired behavior. Historic data will be incorrect.
