Office Insiders on iOS devices have gained several new features across Outlook, PowerPoint, and Excel. Outlook has the most new features with added support for shared mailboxes, SMIME for email encryption, and marking individual messages as unread. SMIME allows users to sign and encrypt emails to make sure that only those with the correct credentials can view content on mobile devices.

Excel has also gained a new feature in dynamic arrays. These allow you to type a formula that returns multiple values and have it automatically appear in neighboring cells. Microsoft released a blog post breaking down this feature last month.
