just wondering if there is a way to setup word suggestions, or auto complete of commonly used word in email body?

There is no such build-in feature in Outlook. You may need to use some 3rd-party tool or input method to realize this feature.

By the way, you can look into this features in Outlook, which may be helpful to you as well:

AutoCorrect spelling, and insert text and symbols
