Symptoms
Assume that you create or edit a new role group in Admin Roles by using Exchange Admin Center (EAC) in a Microsoft Exchange Server 2013 environment. When you set the Write Scope to a DatabaseScope type, the role group still shows the Write Scope setting as Default.
Cause
The issue occurs because the Exchange server unexpectedly ignores the DatabaseScope type when you set the write scope in EAC.
Resolution
To fix this issue, install Cumulative Update 13 for Exchange Server 2013 or a later cumulative update for Exchange Server 2013.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
