Exchange 2013

All mailboxes is on the Exchange 2010, and all is working fine.
I have installed an Exchange 2013, and they can see each other, and everything looks fine.
I have migrated a couple of test mailboxes to the Exchange 2013, and they cant connect through Outlook 2007.
The error is that there is no connection to Microsoft Exchange, and that Outlook has to be online.
If I on the LAN connect to the Exchange 2013 OWA with the moved users I can send and receive mail - the Exchange 2010 is still the HUB Transport server.

Off course I cant move the users mailboxes before this is solved, so please help me solve this.

What is protocol you used on your Outlook, RPC over HTTP or any other protocol?
a.    If you use RPC over HTTP, I suggest you use this tool to do a test, If there is any error, please paste here in your next post.
Exchange Remote Connectivity Analyzer

b.    If you are using MAPI or any other protocols, please check the firewall setting on your computer, disable firewall and anti-virus software to have a try.
     
3.    As you can sign into via OWA, this may problem on your Outlook. Please recreate the profile to have a try.
 
4.    Please check the event log on your desktop, if there is any error, please paste here in your next post.

Thanks for your answer:

Here is my answers to your questions:

a. I dont get any specific errors, just time outs

b. Disabling the FW and antivirus does not help

3. Does not help to recreate profile

4. Here is something from the log:

There is no connection to the Microsoft Exchange. Outlook has to be online or have connection to perform the action.

Check the user account is locked , try resetting password.

Check client compatibility , upgrade to the latest Outlook service pack.

For Windows XP users ,if you are not using Outlook Anywhere for external users , keep the External url field for OA blank
