To connect your Outlook or Office365 accounts with a standalone LiveAgent installation, you need to set up a Microsoft application and then connect it with your LiveAgent installation. The whole process is not complicated. Everything is explained in the six steps below.
1. First go to https://portal.azure.com and login with your Microsoft(outlook) account. After login you'll be redirected to the Microsoft Azure dashboard. Click on App registrations.
2. On the App registrations screen you will find all your existing apps. We need to create a new one for LiveAgent. So click New registration at the top of the page.
3. Name your application so you know what it is used for. Set Supported account types to the second option Accounts in any organizational directory and personal Microsoft accounts. At the Redirect URI section select Web from the dropbox and then set your redirect URL to https://your.domain
4. After successful app creation you'll be redirected to the application dashboard. Here you can find the Application ID that you will need for the last step of the setup. Copy it.
Now we have it all connected and LiveAgent is ready to connect with your Microsoft email accounts. Please follow this guide to do so: https://support.liveagent.com/893604-Connecting-LiveAgent-with-your-Outlook--Office-365-account
