Using Background Images with Teams Meetings

Teams supports the selection of an image to use as the background for meetings. For now, you can choose from a set of images selected by Microsoft, but soon users will be able to upload their own images and use them in Teams meetings. While we wait for Microsoft to complete some work on admin framework to control image upload, a workaround is available to use custom images today.

Petri GET-IT for Teams Virtual Conference

Petri.com is running a free 1-day virtual conference on the topic of Microsoft Teams on August 12. All are welcome to attend.

The Microsoft 365 admin center includes the ability to manage settings for the default Exchange Online authentication policy.

Characterizing backup of Exchange Online mailboxes to PSTs as brain-dead might have been harsh, but it’s an accurate assessment of the worth of this idea. Plenty of cloud-based backup offerings exist that can process Exchange Online data more securely and at scale.
