I have a user that works twice a week, and each time she comes in it takes about 3 hours until she can connect to the server to send and receive email. I have checked all settings and all are standard to the organization. She is able to connect to all other network resources and the internet. When I click send and receive it stalls on the receive step and finnaly returns the error message: Task 'Microsoft Exchange Server' reported error (0x8004011d): 'The server is not available. Contact your administrator is this condition persists.
Any suggestions would be great.
