After deactivating a user account, you may need to reactivate it at some later time. Because the user information still exists in the Microsoft Project Server 2010 database, you simply need to change the account status from Inactive to Active.
Before you perform this procedure, confirm that:
You have access to Project Server 2010 through the Microsoft Project Web App site.
Important: The Manage users and groups global permission in Project Server 2010 is required to complete this procedure.
To reactivate a user account
Use this procedure to reactivate a deactivated Project Server 2010 user account. After you have performed this procedure, the reactivated account is able to access Project Server 2010.
Reactivate a user account:
On the Project Web App home page, in the Quick Launch, click Server Settings.
On the Server Settings page, in the Security section, click Manage Users.
On the Manage Users page, in the Users list, find the user account you want to reactivate. (You can use the Search box to search for a specific user.) Click the user name of the account.
On the Edit User page for the selected user, in the Identification Information section, select Active from the Account Status drop-down list.
