When trying to log into a meeting using the Join meeting link in Outlook. The link opens up the option to Download Teams, Continue in Browser or Open Teams (work or School). Previously, when I clicked the don't he link, it would take me directly into the meeting, now I have the following options. Please reference the screenshot of what appears currently. This is my work Teams account not personal.
Try a reinstallation of the Teams desktop app. Remove via control panel or just install it over the current installation. Before that you can also try and sign out of Teams and Outlook desktop manually, top right corner for the former and top left corner for the latter (account).
