We are currently running IIS 6.0 on Windows 2003 Server with Exchange 2003 for the purpose of accessing our emails via our smartphones and/or OWA. It's recently been brought to my attention that our SSL certificate expired on 6/15/13. I was told by our IT consultant that it'd be easiest to request a new certificate then to renew it. I'm finding plenty of information on how to request a brand new certificate or renew an existing certificate, but I'm not certain about how to proceed if there's already an expired cert. in place.
At this point, I haven't heard of users not being able to access emails on their phones, but we do have some data collectors that our surveyors out in the field use that aren't. My best guess is that I should choose to remove the current certificate while in the IIS Certificate Wizard, but wanted to confirm to help minimize potential downtime.
Thanks in advanced!
