Microsoft Word Forcing "Spaces" Switching

When I have Microsoft Word on one “space” (virtual desktop in usual english), sometimes clicking anything on another “space” forces me to go back to the "space" where the Word window is opened. How can I prevent Word from behaving this way?

Note: This is a blind answer attempt: I don't have Microsoft Office on any of my computers.

Could you try:

System Preferences
    Mission Control

to deactivate:

    ☐ Automatically rearrange Spaces based on most recent use
    ☐ When switching to an application, switch to a space with open
               windows for the application

I deactivated both because they were always disturbing my working environment in a way I wasn't able to go ahead with what I was running in parallel on many spaces. Since I made this setting I'm able to work with an environment not running under my feet.
