If your meeting reoccurs on a regular basis, enter the start and end date/time for the first meeting and then use the "Repeat Meeting" functionality to schedule the remaining meetings and they'll all be schedule using the same meeting id. Another option, or if your meeting recurs irregularly, is to create a "default" "My Meeting" that you can use at anytime. It will create the meeting link and meeting id that can be started at anytime. You would then just schedule your recurring meetings in Outlook and include your meeting info. You can create your "My Meeting" by logging-in, go to setting under your profile and you'll see it under "Default Scheduling Options." There's probably an easier way to do that, so check the Knowledge Base.
