Hi,

I'm having a real problem setting my business Outlook account up, we have a SBS 2008 running Exchange 2007.

When I enter all the settings I keep getting a certificate error, and where as with Symbian, IOS and Android you simply accepted the certificate there is no option to do so.

I have exported and mailed via another account the certificate and installed onto the phone but still the same issue. I'm no expert on Exchange but it looks as though the issue is to do with the fact that we use an IP address as the server address rather than a DNS, but the certificate references the DNS the server thinks it should have and not the IP address. As such the phone can't relate the certificate to the server.

Has anyone had a similar issue?

Im thinking we need to recreate the certificate but this would of course affect all other users.

Any ideas?

I'm not sure if this will help but it seems to have worked for the OP, so i will leave this link here, try it and see:

Hi,

Tried that as I had seen this post and similar posts on other forums but no joy, thats what makes me think its an issue with the actual certificate.

I´m having the same problem, with no solution at the moment, I have to use my old phone until this issue will be resolved.

Have you installed your certificate on the phone? And what do you use as the server name, an IP address or a FQDN?

I'm using a free StartSSL certificate for my Exchange server... and while on Windows this is trusted, it is NOT trusted on Windows Phone 7.  After installing the StartSSL root and intermediate (copied it to Skydrive and opened it) it now works fine on my phone as well.

And what are you defining the server as within the phone, the public IP address or DNS?

I suggest to fix the root issue... and that's your Exchange server setup.

Otherwise you need to post your IP-address so we can check what's really wrong.

I had the same problem with my Lumia 800. It is Windows Exchange and a Windows Phone. Why is there a problem ? Got an answer from the Helpdesk, you have a certificate which is not recognized by windows. You have to Buy one, costs 200 euro. I havn't spend more minutes to this Market protection issue. I have sent it back !!!!!

This definitely a certificate error with the server and not something that should be ignored. Certificates are there for a reason.

Denouter1969 Microsoft exchange and Windows Phone yes but exchange has a certificate system for a reason and that is one of securtiy. If you're company can afford to have an exchange server then they can afford to have the right certification.

We have a closed "ecosystem" for testing purposes and thus using self signed certificates with exchange server (among the others as well). This (using self signed certiticates) has not been a issue with any iphone or android phone so far...
