Outlook errors when connecting to exchange 2010
Posted on 2011-03-19
I am using Win Server 2008 R2 Std SP1 and Exchange 2010.
Clients are Outlook 2003 and outlook 2010, this issue is the same for all users.
Outlook will allow me to set up the profile and the server is discovered by the client (server and username underlined), only when I try to start outlook do I get the following messages.
Offline file switched on, on opening outlook I get the message - "Cannot Open your default email folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your outlook data file (.ost)"
Offline files switched off, on opening outlook I get the message - "Cannot Open your default email folders. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance"
After clicking OK outlook closes.
I get the same message from Outlook 2003 and 2010, with security enabled or disabled (client and server.)
I have installed Outlook 2010 on the exchange server also with the same error
I am able to access the mailboxes via OAB, using "server name" or FQDN in the browser.
I can send and receive internal mail, I can send mail out to external addresses (No receive for external mail configured as this is still used with pop3)
The only information that relates to this is ref to "RPC encryption requirement" this does not appear to be that issue.
Any pointers please?
