Exchange 2007 Certificate

Hello,

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?

Cheers,
Goraek

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

New-ExchangeCertificate -SubjectName "c=ES, o=ur company de Bicicleta, cn=mail. domain.com" -DomainName externaldomain.com, mail. domain.com, autodiscover.externaldomain.com, EXCH.internaldomain.com -PrivateKeyExportable $true

[Note: Please change the above url to the urls used by ur users before running]
