Exchange 2010 / Outlook 2010 CA issue with selfsigned certificate

Hi all,

I have recently installed Exchage 2010 and now it's saying that root ca is not authorized.

I have generated a new certificate with all the SAN names using the selfsigned service however it's still showing up that it's not authorized CA.

We as this is going to be used for internal only we are not looking to purchase any 3rd party certificate.

Could anyone kindly place me into the right direction?

I read somewhere that in Outlook 2010 they changed it.  In Outlook 2007 it would skip some SSL validation process which stopped pop-ups for self signed SSL.


have you tried to import the self signed SSL into the user's computer?

Import the SSL into the Trusted Root Certification Authorities store.

I wanted to avoid doing that.

I have previoiusly done this with exchange 2007 and office 2007 without in need to install the root ca I was able to avoid all the pop up I get in Office
Problems using Powershell and Active Directory?

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

Why not install your own Enterprise CA, that way all domain joined clients will trust it?
A self signed certificate will never be valid when viewed
Outlook 2007 and later clients will ignore the self-signed cert when using SCP

I thought about placing the own Enterprise CA but we don't have any Enterprise 2008.

It would totally make sense that Office 2010 made the change because the setting is exactly the same with exchange 2007 and it doesn't give me any error what so ever.

We end up purchasing the certificate but thank you for the information on office 2010.
