Unable to add calendar/meetings to Outlook from SharePoint Tab in Teams App
When you click on Add a meeting button in a group calendar it does not take any action using the Teams desktop app. However, the option works in the SharePoint and Teams Online.
More Details: It happens when you add a SharePoint page as a Tab in the Teams App and have a Group Calendar web part.
