FaroX321 it is a frustration that many features from Microsoft get delayed but what I have understood from the Microsoft care team that is assigned to my organization is that the developers looking after Teams (for example) have many many considerations to allow for when trying to release features. It is not as simple as we (the consumer) may think where they just turn something on and hit a button to release it to all tenants across the microsoft estate. Features released can have an effect on application preformance, or integration with a different app somewhere. So they just have to make sure as much as possible is in control before releasing so that we, the consumer, get the best from it as soon as it is released. With the feature on co-organizer role there is a huge anmount of permission based scripting behind the scenes that Microsoft have to make sure is smooth and bug-free. It has appeared for me in my tenant just last week and it will be a huge step for easier, smoother meetings with more than one person now able to control things during the meeting. Click on check for updates and see if it has now appeared for your tenant.
