Standard Exchange Online Protection was also updated.

2. New auto-expanding, highly scalable archiving came via an architecture update that allows both end users and admins to take advantage of very large archiving storage. More on the Office blog here.

3. Office 365 Web Apps were improved with updates that covered notifications, help features, contextual settings, and the integration of Skype for Business conversations. The rollout of these features will continue for the next several months.

4. Updated access and security controls were added for Outlook for iOS and Android; now, Outlook uses Active Directory Authentication Library (ADAL)-based authentication for Exchange Online mailboxes in O365.

Lastly, the iOS and Mac sign up experience was simplified so users can more easily share notebooks. More on the Office blog here.
