Hi, I have installed and configured MS Exchange 2013 server with SP1 and CU9 on MS Windows 2012 R2 server. The server is an additional domain controller (There are two more domain controllers including one DC) and has local DNS as well. Exchange server holds both the roles in single box. DNS lookup is configured with local DNS and SmarthHost is being used for outbound emails.The POP3 and IMAP clients are fine but having following two issues...
1. OWA clients are not able to send email. The email stuck in DRAFT folder. Got error message that "You do not have appropriate permissions to perform this task".
2. MS Outlook 2010 Exchange clients also have sending emails but their emails do not go in draft. The email exists from outlook and vanished. Means emails do not reach to recipients neither they queue up in system.
I shall be grateful for and earliest possible solution.
