Let's Encrypt with Exchnage 2010

[Moh]

Hello there,

I work as IT Administrator and we still having Exchange 2010, (IIS7.5)

the certificate of exchange will expired tomorrow and we used to US Internal CA, but NOW we decided to used Let’s Encrypt certificate.

So is there any fast and easy way to get Let’s Encrypt CA?

I already have CSR (Request) file but still pending to get a the certificate.

Thanks

Hi,

How did you requested the certificate? (What method, using which software?)

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

It produced this output:

My web server is (include version):

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know):

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

Thank you

I made the CSR (.raq) by exchange management console

Is the Domain resolveable by outside DNS servers (and could connect to your real server?)

Please fill the form i shared to you…

Hi,

Your options are limited… (in your case, since you are using Network solutions’ DNS server)

In order to obtain a certificate, you’ll need to use either HTTP based validation or DNS based.

If you want to use http based validation, you should open port 80 and setup your IIS server to serve challenge tokens when you request / renew a certificate. (there are several clients that could help you serve that tokens, see https://letsencrypt.org/docs/client-options/ for client options)

If you want to use DNS validation, you’ll need to manually add DNS challenge records into your DNS control panel… (Check https://letsencrypt.org/docs/client-options/ for client options)

Thank you
