Microsoft Teams and Meeting Update Tool for Skype for Business

We don't currently have Exchange Hybrid setup, so the MMS service will not work at the moment. Only Exchange 2016 on-premise.

In the MMS documentation it says that you can use the Meeting Update Tool for Skype for Business, but I have ran this and it is not picking up any of the Skype for Business Online meetings?

In these situations, end users can use the Meeting Migration Tool to migrate their own meetings instead.

We have a SfB hybrid setup and all of our meetings take place in SfB Online.

My account which I am testing with has the co-existence mode of Skype for Business with Teams collaboration and meetings set.
