Cause

The configured service account for the ENow Client and ENow admin services that run on the Exchange 2010 Client Access servers does not have the Reset password permission for the Client Access test account. Usually the account name for Exchange 2010 environments starts with "extest_"

Resolution

Please assign the service account as a security principal of the extest_account and assign it the "Reset Password" permission:
