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 don't need the request.  

Is this for Exchange?  Which version?

If it's Exchange 2010/2013 you can do it through the interface.  If it's 2007 you must do it through the command line.

Here is a great read.

You can install it through the Certificates MMC.  Once installed, you assign to the site through IIS.
First, you have to put the certificate into the cert store...
If all the certs are the same, just different formats, you can just double click one of them. If these are different certs, double click them all.
Dependent from the content, it should be put into the correct store.

It has to be in the computer store...
You open an new mmc, add the certificates snap in and select computer...
Open My Certificate - Certificates if the certs are there....
You can open the properties of each cert and put in a friedlich name, it makes it easier to find back the correct cert in IIS.

The you open IIS, go to your web (i.e Dafault Web Sites), click on bindings, select the https binding (if not there add https) and there you can add the cert from the store....
After assigning the cert, IISReset.

Thanks, how can i know which content or what content to determine the cert store?
Content of the certs means mainly the subject name and alternative subject name inside the cert.
If you request a cert, it is mainly because you need a certificate for a server, user or service.

If  an user accesses i.e. a web site via SSL, the browser get this certificate from the server and checks the certificate for validity as well as the name inside. If everything is fine (cert valid, requested name inside the cert), the cert can also be used to encrypt the data transfer.

Dependent from the request, the content of the cert is different. A user certificate contains mostly a name like an e-mail address, a computer certificate contains mostly a name of a computer. Also there are some different information inside the cert for the purpose and usage. If you import such a certificate, the import mechanism usually can determine what kind of cert it is and puts it usually into the right store....

If the cert is imported into the wrong store, you can not see it from IIS

If you request a certificate from a public authority, they create a certificate and may provide it in different formats to make it available for all kind of OS and devices.

you install all of them in personal via MMC certificate

After you installed, check whether they have private key or not.
If not, there are kind of useless for IIS usage.

Thanks. Is it possible to see whether I have a private key from the files I have already (above extensions). Or is it a separate file?

If you open the cert, have a look on the first page, under Valid From there is written "You have a private key that corresponds to this certificate".
