Best practices for successful large meetings in Microsoft Teams

Anna_Petts I believe you are asking about using PowerPoint Live? We've been successful with PowerPoint Live (800+ presentations so far) by following a few tips. The most important thing we've found is paying attention to the storage size of the PowerPoint file. We try to get them down around 20-30MB maximum (most end up under 10MB). The first place to look is at images - often users will take photos from their smart phone and directly use them without understanding the file size (or image resolution). PowerPoint has a built-in feature to reduce image size (and remove cropped portions of images). We've taken a 520MB file down to 11MB using this feature. As PowerPoint Live pushes the deck to attendees, loading 11MB is much quicker to load and manage than 520MB. If presenters are embedding video, those can also be optimized with PowerPoint (good to drop the resolution down to the size of the video on the slide - for example, if only taking half a slide, drop the resolution to 720 or 360). We typically recommend embedding a YouTube video (instead of the entire MP4 in the slide). With those changes to a deck, we'll put them through a quick PowerPoint Live session to check them - and observe if there are any key issues with animations or transitions - just have to understand not all animations/transitions are supported in a browser.

If you have problems with the slides staying coordinated with attendees, you want to "click the eyeball" icon to prevent attendees moving on their own through the slides.

We love PowerPoint Live because:

• it enables the presenter to easily see their slide notes (presenter view) on a single monitor or laptop; 
• allows multiple presenters on the same deck to switch between controlling the slides (no need to EVER say "next slide");
• if the presenter drops their connection, the deck remains active and visible in the meeting, ready for the presenter when they get reconnected;
• less bandwitdth needed by attendees (important with our increase remote work);
• for our international attendees, they can translate the slide text into their native language;
• and (super cool) any hyperlinks on the slides can be clicked on by the attendees - the slides are interactive!
