Microsoft 365 Apps subscriptions for Business and Enterprise The following Office Update Channels, newest to oldest, are available. Based on which channel you are in and which license you have, you’ll get certain updates sooner or later than others.ĭepending on your subscription and installation type you can control which channel you are in. Microsoft 365 Apps (previously known as Office 365) has multiple update channels. How can I force Outlook to install the latest updates? I chose File-> Update Options-> Update Now and I got the message “You’re up to date!” When I compared my build number of Outlook 2016 to the one of a friend, I saw that his was newer. I sometimes see announcements about new features being added or fixes being made to Office 2016.
