Do I need an on-prem SSL Cert after migrating to Office 365?

We've migrated to office 365 and my old SSL Certs (from our on-prem Exchange server) are expiring. Do i need an SSL Cert for Office 365? Part of the reason i ask is because we're getting "A secure connection cannot be established with the server xxx.office365.com on our Apple Macs.

BTW, You were getting that specific error because there was an issue with certificates on September, 13th, on office 365 part. Just for the records.
