Hi,
I have some code for accessing a mailbox of several users using an impersonation account with the role ApplicationImpersonation. This code works against my Exchange 2010 server. But when I run the same code against my 2013 Exchange server I get the error "The impersonation Principal is invalid" Account is configured on both servers with
New-ManagementRoleAssignment Name:impersonationAssignmentName Role:ApplicationImpersonation User:serviceAccount
Any ideas?
Regards
Danny
