I'm setting up an Exchange 2010 infrastructure, and am in the lucky situation of having four Exchange servers. My company has a single domain and one site. Two of the servers are running the Client Access Server and Hub Transport roles, and the other two servers are running the Mailbox roles and a DAG. Originally all three roles were running on the two latter servers, a CAS Array was created and I was going to use Hardware Load Balancers, but instead I decided to buy two new servers and transferred the CAS and Hub Transport roles to these, and am using Windows Load Balancing.
I have some test 2010 mailboxes and get the message "Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your offline folder file." when setting up an Outlook profile.
Microsoft Knowledge Base article 982678 does not apply because all the existing mailbox databases have been added to the CAS Array.
Can anyone help?
