If creating a new Event, select Videoconference (Teams in my case), add participants and send,
the participants get an invitation without a teams link.
It seems eM Client is sending the invitation before the Teams link was created.
It is added to the local calendar Event, but participants are never updated to get it as well.
Best would be to wait until the Teams link is created by the Teams server, update the Event, and send the invitation then.
It is quite complex, but generally the link is created by the API when the event is saved in the calendar. Not before.
If the participants are not getting links to the meeting in the event sent to them by your server, we would need to see some logs which would tell more about what is happening.

Ok, we will buy our pro licenses tomorrow and will open a ticket.
