Microsoft Office Autoupdate / High Sierra

What versions are you speaking about? What version of MAU were you on and what version are you trying to upgrade to?

I am running this on my High Sierra machines and it seems to work fine. Sitting at version 3.11.171010. This what version Jamf says is the latest version. I know 3.12.17110800 was released but MAU does not seem to update to this version. The only way I have seen it installed is when you install an Office application fresh with version 15.40.

Dear Yager,

the Download Link for AutoUpdater can be found here:
Auto Updater

In the Third Party Products Section you also find all the necessary Links for:

Office for Mac 2011, which is no longer supported by Microsoft, see:
Office 2011 for Mac

And the Download Links for Office for Mac 2016
Office for Mac 2016

which contains the direct Links to the Download Pages on the MS Website.

I am running at present both Versions, but will shift all my Macs early next year to Office 2016 for a year until MS expects to release Office 2019 in the Autumn, that includes a Version for Mac - Details on this can be found here:
Office for Mac 2019 Announcement

I have not seen any Challenges with either Version, if you install High Sierra without APFS.

If you install High Sierra with APFS, Microsoft had announced, that Office 2011 will not function properly & that you would need Office 2016 in Version 15.35 or higher, at present you can find Version 15.40 online, in the Links above.
