We have a renewal coming up from GoDaddy on owa.spcala.com SSL certificate.   We used to use that for accessing our internal Exchange server from the web.   We now use Office 365 for email.   Do we still need this site to have a certificate.

Hi,

if you have migrated from Exchange to Office 365, and you have decommissioned/ removed exchange from your organization, then there should not be any reason for cert renewal.

I guess that on that certificate, you have more names then just owa.spcala.com? Usually owa and autodiscover are used for exchange. If you have some additional names, then maybe that certificated is used for some other services, like sharepoint, lync and such.
Check the names on it, and then determine where are they pointing to, via public DNS. That should tell you if they are in use.

Regards,
Ivan.

Thanks.   The name pointing to exchange.spcala.com we don't need.   What would the autodiscover.spcala.com possibly be used for?   spcala.com is our website.

Hi,

autodiscover.spcala.com is used for automatic configuration of Outlook and email on mobile devices.
Since you are using Office 365 now, then that record is most likely pointing to Office 365, and you don't need it anymore.. but do check where it is pointing :)

Regards,
Ivan.

You can use ping autodiscover.spcala.com

It says that it is pointing to autodiscover-emeacenter4.outlook.com. So this is Microsoft, not your local server.

Hi,

no, it means that you don't need it.
If that record would point to your server, then you would need it, since when client connects, the certificate would be presented.
In your situation, record is pointing to Office 365, so you don't need it. You need the DNS record, but not the certificate it self.
