Question : configure OWA to use SSL

I'm trying to configure OWA to use SSL following this guide: http://www.petri.co.il/configure_ssl_on_owa.htm
as suggested to me by an expert here.

 I’m in the process of creating a certificate. On step 8, on the Delayed or Immediate Request page, it is prompting me to click Send the request immediately to an online certification authority, but that option is greyed out. I only get ‘Prepare the rquest now but send it later’.

Does anybody know why?

Many Thanks in advance

Answer : configure OWA to use SSL

It expects you to have a certificate authority setup on your domain. (This is certificate services running on a server) If you purchase your cert from an external source then you should choose the ‘Prepare the rquest now but send it later’ and send them the file.
