Exchange 2007 Certificate


We have a Windows 7 with Office 2010 in the environment.
We have multiple servers running on Windows 2003 SP2 with Exchange 2007 SP2.
When the user opens Outlook 2010 on their Windows 7 machine, it prompts to proceed with Yes No View Certificate.

It is showing as "The security certificate was issued by a company you have not chosen to trust. View the certificate to determine whether you want to trust the certifying authority."

How do we go about automatically install the certificate without having to install the certificate manually?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can either buy a 3rd party certIficate or install your own Enterprise Certificate Authority which all domain joined clients will automatically trust.

create a self signed certificate and push it using a group policy . u will not have to install a Certificate Authority in this case

Open ur exchange management Shell and type the below command to renerate a self signed certificate
