If Microsoft Office for Mac is installed by some method other than directly from the Office 365 portal, you receive the following error message even though Office is installed successfully:
Office 365 Enterprise E3 setup is incomplete.
This behavior is by design. The message can be safely ignored.
To prevent this message from appearing, remove Office, and then reinstall it from the Office 365 portal.
