So, I did this once with one of the certificates. &nbsp;It installed just like the webpage said it would. &nbsp;It's almost although I have an &quot;extra&quot; certificate lingering around. &nbsp;Like I said, exchange is working. &nbsp;How can I trace back the certificate that's bogus or un-necessary?
</div>


<div>
I have attached a copy of the certificate that complains when launching Outlook. &nbsp;I have also attached a screen shot of the &quot;good&quot; certificate I have already successfully installed. &nbsp;Where does the extra one get stored. &nbsp;I do not see it on the server under the Certification Authority -&gt; Issued Certificates....<br />

See the attached image <br />
<br />
The certificate should be present in the Personal -&gt; certificates folder <br />
<br />
It should then on EVERY client be installed to the folder where the arrow is pointing.<br />

<div>
Did you still need any help with this ?<br />
<br />
Let me know if you have any questions and if you were able to resolve this.
</div>


<div>
No, still questions. &nbsp;I try and store there on every local computer, however; it doesn't get stored. &nbsp;Every time I launch outlook, it pops up again.
</div>


<div>
I had to google how to do it in Server 2008, but the answer was to push it in the GPO. &nbsp;Thanks for the help!

<div class="content wysiwyg-content">
I recently had to re-install SBS2008 at a client site. &nbsp;I can't remember how I setup the self-signed certificate authority on the server in order for Outlook to correctly work without the attached screen shot pop-up. &nbsp;I have tried 6 ways from sunday to install the certificate. &nbsp;E-mail works, OWA works, I just need this pop up to go away. &nbsp;I'm hoping someone more versed in Certificate Authority and exchange could help.<br />
