Hi @IniobongNkanga-8038 ,
He cant schedule a teams meeting via Outlook Calendar on their MAC PC.
The options for Teams is not there.
According to this official document, "the Teams Meeting button in Outlook for Mac will appear in the Outlook for Mac ribbon if Outlook is running production build 16.24.414.0 and later and is activated with a Microsoft 365 or Office 365 client subscription", so first of all, please make sure these prerequisites have already been met.
With the above confirmed, please check if the user is using the New Outlook for Mac, If yes, it's the expected behavior that there's no Teams Meeting option on the ribbon anymore, instead, we can turn on the toggle of "Teams Meeting" when scheduling a new event from the account which has the Teams license:
