In our company we installed some years ago SBS2008. We have bought a SSL certificate (Standard UCC SSL Up to 10) from GoDaddy and installed in in our SBS server to manage connections with Exchange/OWA
Common name is mail.ourcompany.com (our public SBS IP address is resolved as mail.ourcompany.com)
We have also some alternative names:
ourcompany.com
aaa.ourcompany.com
bbb.ourcompany.com
we have installed the same certificate also in some other web servers (with different IP addresses) that we have on premise. Everything is working fine...
Now we want to migrate to Office365. At the beginning we want to migrate only the mail server (keeping our web server and sharepoint server on premise)
Do we need to do/change something in out SSL certificates ? Do we need to have other certificates for our online exchange ?
Thank you
