Microsoft Outlook is an application developed by Microsoft that allows users to manage their email and calendar, store names and numbers of their contacts, and even track their tasks. It has a lot of features that help users become more organized and productive during work. You can sync with other Microsoft apps which include Microsoft Office, Skype, and OneDrive.

For those who want to further enhance their privacy and security while using Microsoft Outlook, implementing a proxy server is an excellent option.

Keep in mind that setting up Microsoft Outlook to work with a proxy server might be more involved compared to other applications due to the additional steps required. However, don't worry, as we will guide you through the process step-by-step. Make sure to use an HTTPS proxy, as HTTP proxies are not supported by Outlook.
