New OWA Becomes The OWA on July 22

Microsoft has announced that the switchover to the new OWA interface will start on July 22 when Office 365 tenants in targeted release will lose the chance to toggle back and forth between the two interfaces. By the end of September, everyone will use the new OWA. Let’s hope that Microsoft has fixed all the functionality gaps by then.

New OWA Includes Office 365 Groups Management Interface

The new version of OWA boasts new abilities for owners to manage Office 365 Groups. The new UI is pretty slick and a welcome upgrade to the previous capabilities. You’ll still need to revert to PowerShell to manage some aspects of Office 365 Groups, but not as many times as you used to.

OWA’s ThirdPartyFileProvidersEnabled Setting

The ThirdPartyFileProvidersEnabled setting in OWA mailbox policies controls if Exchange Online mailboxes can access services like Drop and Dropbox for attachments. Office 365 tenants need to decide if they want to allow this kind of access. There’s both good and bad in the feature, but it’s easily turned off if you feel the need.

The Irritation of Exchange Online’s Inconsistent Mail Tips

MailTips are a pretty useful way of drawing the attention of users to potential issues with email. Exchange Online supports several MailTips, but Outlook clients insist on supporting MailTips in different ways. It’s a small but irritating part of Exchange Online that could be done better.

New OWA Now Generally Available to Office 365 Tenants

The new version of OWA (sometimes called Outlook on the Web, or Outlook Web Access) is now generally available to all Office 365 tenants. Although the new OWA has some nice features, you might want to turn off the user choice (toggle) to move the new UI until you’ve had time to prepare the help desk, documentation, and that sort of thing.
