Avaya Vantage™ built-in Unified Communication (UC) experience can access your Microsoft Exchange Calendar information. This information is displayed in the Calendar tab.
You might need to log in to the Microsoft Exchange service manually or be logged in automatically, depending on how your administrator sets up the service. For example, if your administrator enables the Microsoft Modern authentication mechanism, the Calendar tab takes you to a web page for entering your Microsoft Exchange credentials.
Use this procedure to log in to the Microsoft Exchange server manually.
Note:
If you log out of Avaya Vantage™ built-in UC experience and then log in again, you are not automatically logged in to your Exchange calendar. You must log in to your calendar service again.
