2007 outlook cannot connect to exchange 2010

However cleints still using 2003 outlook can make the connection to the 2010 exchange server.
We are using active directory 2003. All of this has been working for a long time now, just quit working last night.

Also if I try to setup my e-mail on a system running 2003 outlook my mailbox still fails, I think this is due to because it was a 2007 mailbox?

The specific error I get is:
Cannot start Microsoft Office Outlook. Cannot open the Outlook window. The set of folders cannot be opened. The attempt to log on to Microsoft Exchange has failed.

The difference between Outlook 2003 and 2007 is that 2003 contacts the mailbox server role and 2007 contacts the Client Access Server role. If 2007 clients stop working, you should troubleshoot the CAS.

How do I check for issues with that?

The Event Viewer is always a good place to start :)
Also you can start Outlook with the /RPCDIAG commandline option (see: )
It may provide you some information on what connections are failing.

That sounds like a client error?!?
Did you check the CAS servers' event log?

We got it working now, it eneded up being our exchange 2010 server added a bunch of mailboxes into a quarintine. We had to go into the quarintine and delete these mailboxes from that area and everything works now. Aperntly this is new to 2010 and it automatic and cannot be turned off.

Presume you picked this up from the app event log event 10018 ?

If you have SP1 on exchange, you can run the new command Mailbox Repair Request on the errant mailboxes to see if they can be fixed

Great spot btw
