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.
Microsoft will deliver a set of five seminars about Outlook Mobile starting on March 14. It’s always good to gain some knowledge about an important technology. Outlook Mobile is important to Office 365 because it is the most functional email client available. If you don’t believe me, attend some of the seminars and make your own mind up.
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.
The new version of OWA is maturing and new features are turning up on a weekly basis. You can now schedule a Teams meeting from OWA and the prospect of joyful animations hang in the air. But only for Office 365 users as there’s no sign that the new OWA will come to Exchange on-premises servers.
Microsoft has refreshed the Outlook Mobile architecture. They suggest that you run some PowerShell to report clients connecting via the old and new architectures. Their code works, but we think ours is better.
