SSL cert security alert

Exchange 2010 on a SBS2011, after a power blackout
Users with Outlook are getting a pop-up when they open Outlook
"Security Alert"
remote.domain.com
information you exchange with the site cannot be viewed or changed by others. However, there is a problem with the site's security certificate
do you want to proceed.

the strange this is this certificate expired a couple years ago and it was not renewed, now this is popping up after the power blackout. Any suggestions?
Would rather not renew, the certificate used to be used for Microsoft Remote Web Access
thanks

How long has it been since that server was rebooted before the power outage????

Outlook should report on a cert expiration every time that you open it (after a cert has expired).

SBS 2011 has a console for all of the management tasks.  It would be unusual for a powercut to cause a certificate issue unless the date/time on the server is wrong after the powercut - which would potentiall indicate a flat mainboard battery.

With SBS2011 Windows SBS2011 Standard Console

Select Network icon in the top bar > click the Connectivity tab > click on 'Fix My Network' this may take a minute or two to appear

Let the wizard search for problems and it should find the expired certificate. Uncheck all the checkboxes except the certificate one and click Next.  You will then get a new certificate issued.
