MS Teams informs that the meeting is hosted outside of the organization while it isn't

I've recently started using Copilot to create brief summaries of the meetings. I know that it can only be used if meetings are hosted within the organization.

However, for some meetings I cannot use it because MS Teams informs that they are hosted outside of my organization... but in reality there are no participants (including the meeting organizer) who are not a part of the organization.

Does someone know how to solve this issue?

I would be really thankful for the support!
