organize internal workshops

Hello members,

I have a nice question for you, at least I think so.

Is there a possibility in Outlook, or alternatively Teams, to have employees register for a workshop?

I have 4 staff meetings to schedule, but places are limited. The first 10 have a seat, the rest will have to look at another date.

We always do this with an Excel that is filled in, but I wonder if this is not possible in Outlook, Teams or another application.

Anyone have an idea?

I have already tested Polly, but did not get the desired result.

Doodle is a possibility, but is outside our O365 environment.

Thank you very much for your ideas.

Ronny
