Hello from the Skype Business Services Conferencing team!

Hello Markus!

Interesting question, I hope I can provide some clarity but first I would like to understand the scenario a bit better.

If I understand correctly, a presenter joined the meeting prior to the date for which the meeting was scheduled and uploaded some content, like a powerpoint, and then when the meeting actually begins, the presenters are unable to view the content.

Could you please clarify for me:

1. If the steps above are accurate, especially that the presenter actually joined the meeting prior to scheduled date in order to upload content.

2. When the files were uploaded, what permission level was set on them? (Everyone can download / Presenters only)

3. How long of a time elapsed between uploading content and the meeting was held?

4. When the meeting started, the presenters were indeed connected to the meeting as presenters or did their role change as well?

5. Were the presenters able to view the files but not download? Or the files were not even visible in the attachments section?

6. If the organizer joins, is he able to access the files that were uploaded? Is that how you concluded that the files exist but permissions were skewed?
