Office 365

Since last November and the introduction of the Clutter feature (see http://blogs.office.com/2014/11/11/de-clutter-inbox-office-365/ for more details), Microsoft has updated the Clutter feature to allow better management of this feature by administrators. Now, administrators can define retention policies, define rules to bypass Clutter or personalize the message received by end-users.

With the release of the CU 8 for Exchange 2013 and the RU 9 for Exchange 2010, ActiveSync devices will be automatically reconfigured when the mailbox has moved from on premises to Office 365. Previously, the device had to be reconfigured (either by deleting the EAS connection or by manually setting the URL to outlook.office365.com).
