Office 365 Proofing Tools Offline Installer [portable] Today
Microsoft does not provide a standalone offline installer for Office 365 proofing tools [1]. Instead, you must use the Office Deployment Tool (ODT) to download and install them without an active internet connection [2].
If you are looking for a simpler way and have a personal subscription:
- Tier 1 (Base): English (en-us) – Always installed.
- Tier 2 (Regional): Deploy only 1-2 additional languages per user group (e.g., Quebec office gets French, Berlin office gets German).
- Tier 3 (On-Demand): Use the Office Proofing Tools Offline Installer as a self-service option via a network share for ad-hoc needs.
