Request a Certificate for Exchange 2010

For realizing Exchange 2010 new function, I build the related system on Hyper-V environment so that can also understand the Hyper-V mechanism.

At first, I need to request a certificate for Exchange because it always need to be used on communicate between Servers or Client and Server.

Let us begin to learn "How to request a certificate for Exchange 2010" now!


Create new certificate on Exchange Server

• Click "Server Configuration" --> "TEST-CAS-01" --> "New Exchange Certificate..."

• Enter a friendly name as "Adatum Mail System" --> "Next > " button

• Click "Enable wildcard certificate" check box --> Enter "Root domain" as "*.adatum.com" --> Click "Next > " button

• Enter "Organization and Location" information and save a "Certificate Request file" on one path, next to "Next> " button

• Click "New" button

• Click "Finish" button

• Finally, you will see a new certificate that the status is "This is a pending certificate...".  So you have to do the next step --- Let this certificate is valid.

Request the Certificate from a CA
Due to I use the Active Directory Certificate Services of Windows Server 2008 R2 as CA, I will show how to request the certificate from this CA.

• Enter the requested URL to click "Request a certificate"

• Click "advanced certificate request"

• Click "Submit a certificate request by using a base 64 encoded CMC ..."

• At the moment, please open a certificate request file that the previous activity never save as a "reg" format on one path.

• Please mark the content between BEGIN and END New CERTIFICATION REQUEST next to copy it.

• Return to the original request form next to paste it on "Saved Request".

• Change Certificate Template to "Web Server" next to click "Submit> " button

• Click "Download certificate"

• Save as "certnew.cer" to one location

Active Exchange Certificate

• Right-Click the pending certificate next to select "Complete Pending Request..."

•  Click "Browse..." button

•  Select "certnew.cer" file

•  Click "Complete" button

•  If complete Pending Request process,

•  You will see the Exchange Certificate status is from "Pending" to "Valid".

Now the exchange will have a certificate on CAS.

Otherwise, this certificate have no any function now until it be assigned to the Exchange Service as SMTP,POP3,IMAP,UM and so on.
