When creating a meeting in the calendar it is possible to add a adress in the field "Location". Here you're able to pick the adress linked to your customer, but if you want to have the possibility to add your own company adress you're able to add it under configurations.

To set it up, go to "Configurations" -> "Main settings" -> "Basic settings", where you'll see the fields "Company Adress", "Company Postcode", "Company city", "company County" and "Company Country". After these informations have been added, you'll be able to select your company adress in the "locations" field when creating a meeting.
