Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi!
Is the Word you are referring to the one located in the Outlook sidebar? See the image below:
This icon does not open the desktop version of Word; instead, it opens Word for the web within Outlook.
To help you further, I need to know exactly what you meant by "when I open Outlook and click Word so I can use Word." You are welcome to send me screenshots, but please make sure to remove any personal information.
