We are using Office365 for our mail in a hybrid setup so we have an exchange server with the transport role installed but all mailboxes are hosted on the Microsoft cloud. I was wondering if you need to renew your certificate for web mail access?

I have only ever been involved with hosted exchange on site and I know you need a cert for webmail. I contacted our re-seller and they said the cert gets auto-renewed. I'm not totally sure this is correct and obviously I don't want us to have any downtime because of this. Would anyone have experience with Certificates and Office365

All of the Office 365 Exchange CAS and Transport certificates are handled by Microsoft. Most of the servers are *.outlook.com anyway so they are out of your hands.
