Hi;

I have an Exchange Server 2003. I installed new Exchange Server 2010 SP1 in the organization and then i moved all mailbox from Exchange Server 2003 to Exchange Server 2010. All users send and recieve e-mail witout problem.

I can connect to the OWA but i want to send a new mail or add attachment or read an e-mail, i receive the following error;

An unexpected error occurred and your request couldn't be handled.
