Folks,

I have a certificate error I cant seem to get figured out.  The initial certiface setup with this exchange 2007 installation had the wrong CN set, I have since created a new self signed cert with the correct CN and information, the problem is, I cannot apply it when trying to use the Enable-ExchangeCertificate command.  Below is the info for the two certs and the error I get when trying to apply it...

What started me on this quest was trying to resolve some random OOA issues as well as some problems in outlook with the access of calendars, I believe it is all due to the CN for the cert.

See link here for my logic, reason 2:  http://www.proexchange.be/modules.php?name=News&file=article&sid=686

We are using a self signed cert because we do not want to pay for a SSL cert.... (I know, I know, I wish I could use a non-self signed).  But any help as to why I cant apply this cert would be great.  The thumbprints do match, so I am clueless...    Thanks!

Did you actually install the certificate on the local machine before issuing the enable-exchangecertificate command?

I believe so, the cert thumbprint shows up in the list using the "get-ExchangeCertificate" command.  How can I check what you are asking me?

Open up the certificates MMC, start - run - control panel - certificates.  Or start - run - mmc.  Then click on file - add/remove snap-in, click on Add and select certificates.  Choose the local machine and click OK.  Check under personal certificates to see if the certificate is there.

Dark, thanks for the advice turns out i was trying to aply a certificate request and not the actual certificate.  the error i was getting with it being invalid was becuase it was not an exchange certificate, it was a different one?  Anyway, I was able to create a cert and get it applied, but it did not fix the out of office problems.....  I am wondering if the CN in the new cert is still wrong...
