You should experience significant improvements in copy & paste of images within Teams, as well as to & from Teams. We are aware of a few remaining issues, but the most common cases are resolved.
Thanks again for your patience on this one.christophe commented
Same issue here, someone found a better workaround then download the image before you can use it in a mail?
This feature request is still on in the backlog. No new updates available at this time.
We acknowledge the customer demand for Private Channels and have been hard at work on it. Private Channels is currently in preview with a select group of customers. We expect to release the feature to the public later this Fall, and will update here when we are starting to roll out to all customers. We appreciate all the feedback you have provided to us on this forum and thank you for your patience.
Due to prioritization of other work-items this has been moved to the backlog. We will update when it is being actively worked on again.
