I installed the Outlook plugin but the MeetingBooster Tab is not showing

Outlook may have disabled the plugin.

Step 1: Go to File -> Options

Step 2: Choose Add-ins -> Manage add-ins.

Step 3: Press the “Go” button at the bottom of the screen. This will take you to a new window where you can see which Add-ins are active. Ensure that the MeetingBooster add-in is ticked and then press OK.

This will re-activate the plug-in and ensure that it stays active whenever you start Outlook up.
