We’ve got a lot of feedback lately that people want a simple way to deploy the Office 365 updates to workstations that aren’t a member of a domain, and therefore can’t be reached by Group Policy. We’ve gone ahead and created a standalone installer, which can be copied to a desktop and manually run. When executed it installs the recommended updates for Office 365. It does not install Lync. It’s available as a free download on the Office 365 Client Updater page.
If your organization needs a customized version that does something different, like install Lync, let us know and we’ll see what we can do.
