Requirements:
You must have a Business Basic, Business Standard, or Business Premium email plan to install Office apps via the Email and Office Dashboard.
If you already have an older version of Microsoft Office on your computer, you need to uninstall it before downloading and installing the new version that comes with your plan. Find out how to uninstall Office from a computer.
Note: The Microsoft 365 64-bit version is installed by default unless Microsoft Office detects you already have a 32-bit version (or a standalone office such as Visio or Project) installed. In this scenario, the 32-bit version of Office will be installed instead.
To change from an Office 32-bit version to a 64-bit version or vice versa, you need to remove Office first (including any standalone office you have, such as Visio or Project). Once the uninstallation process is complete, you need to sign in again and choose other install options, select your language and version you would like (64 or 32-bit), and then select Install to install Microsoft 365 on your device.
