SBS Server 2008 R2 certificate problems

I have a SBS Server 2008 R2 that has an expired certificate.  Every time one of the users logs into their 2010 Outlook it gives them the error attached.  I have followed online guides to create a new self signed certificate using comandlets in the power shell prompt but I keep getting an error that is telling me there is no such command.  This is one of the commandlets that I have run: Get-ExchangeCertificate | List.  I am running Exchange server 2007 which was configured during the installation process.  As was the original self signed certificate.  Any help would be much appreciated.

Make sure that you are running the cmdlet from exchange management shell not windows power shell.

I have figured that out.  I now have a new Exchange certificate but now the error message is telling me that "the name on the security certificate is invalid or does not match the name of the site when I try and access Outlook 2010 on a client machine.

The version of SBS that you have posted doesn't exist.
Either you have SBS 2008 or SBS 2011. The only variant that is at R2 level is 2003.

As this is SBS, the quickest way to resolve is to run the wizard to configure you internet name. That will generate a new certificate and put it in the correct place.
Ideally you should be using a commercial SSL certificate which would deal with the issues completely and costs $60/year.

My appologies I have SBS 2008 Service Pack 2.  I don't feel that a SSL certificate is the right way to go since Exchange is only used for local domain access.  What wizard are you speaking of?

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

On the Network config in the SBS tool, under Connectivy is Set up your Internet Address. Run that wizard again (you don't have to change anything).

Simon,

Running through that wizard it is wanting me to setup Exchange for external e-mail.  This is a small business that uses Exchange to share calendars and inter-office e-mail that is all so this won't work for me.

This is one of the commands that I am having trouble with.

3.Change the InternalUrl attribute of the EWS. To do this, type the following command, and then press Enter:

Set-WebServicesVirtualDirectory -Identity "CAS_Server_Name\EWS (Default Web Site)" -InternalUrl https://mail.contoso.com/ews/exchange.asmx

This is from a Microsoft knowledge base in reference on how to fix my existing problem.

http://support.microsoft.com/kb/940726

The problem is no matter what I put in for the ews it always give me an error and says that it doesn't exist.  Am I to take this command literally and type it exactly as it reads minus the name of my server?  Of course what I want the InternalUrl to be also.

That is because SBS doesn't use the default web site for the web services for Exchange, it uses another one. If you run get-webservicesvirtualdirectory then you will see what is listed.

Exchange should really be used for all email, trying to use it for just some will usually cause you problems, with email going where it shouldn't for example.
