Plug-ins for Microsoft Outlook and Google Calendar tend to be the most common. This plug-in automatically adds the appointment to your calendar when you create a new meeting, which streamlines the process. Every service we list below has an app for Windows computers, most have one for Mac computers, and two have an app for Linux operating systems.
Check to make sure the service works with your operating system. Some options also have a desktop app you can download, which many users find to be faster and more convenient. Video conference services let you join a meeting using common internet browsers such as Firefox and Chrome.
Having only a few hosts will keep your costs down, but will require all meetings to be set up by these authorized employees.
