Adding outlook to Exchange 2010

After adding a new mailbox and setting up the mailbox in Outlook I receive the following message:

Unable to open your default e-mail folders.  You must connect to your Microsoft Exchange Server computer with the current profile before you can synchronize your folders with your offline folder file.

Exchange 2010 Server, Outlook 2003.  Require Encryption is set on the server to $false.

If the profile in Outlook doesn't have any data associated with it delete the profile basically making it like Outlook's never been connected to exchange.

Depending on the operating system:
- XP: C:\Documents and Settings\username\Local Settings\Application Data\Microsoft\Outlook (delete everything except .pst files which are probably not in there).
- WIN7: C:\Users\username\AppData\Local\Microsoft\Outlook (delete everything except the "Office Address Books" and "RoamCache" folders.

Open Outlook and it should go through the steps to find the exchange server, make sure you're using cache mode and make sure the name in question is underlined, meaning the server resolved the name.

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

check the database settings for the RpcClientAccess server
Get-MailboxDatabase (Get-Mailbox alias).Database | ft Name,Rpc*

this will give you the FQDN of the server your client is attempting to connect
verify you have connectivity to that server (telnet to port 135)
Can you Enable the Encryption on Server and enable on Outlook 2003 and then try to conect

R-R, thanks for the links.  I should have mentioned that I installed all of my Exchange 2010 servers from media containing SP2.  Encryption is disabled by default.  I verified this several times.  I've also made sure to setup Outlook 2003 / 2007 to not use encryption.

works2011, thanks for the solution but no luck.

I'm able to telnet into port 135 on my mailbox server.

Ash007,  thanks for the solution.  I enabled encryption on the CAS and then on Outlook.  The result was the same error message.
You mentioned "Exchange servers" are you using more than one server in the CAS say in an NLB configuration?

Do you get the same error without using cached mode?

I change the certificate used by IIS from my own to the default self signed and the problem went away.

I have two certificates:


I think this is happening because certificate 1 does not have the internal name of the server.  Does this need to exist even though encryption is set to no?

If i'm correct certificate 1 should have the following names:
internal computer name

Is this correct?

mestekAuthor Commented:
Encryption is disabled on the server and the client.  Why would the certificate make any difference?
