How to Fix Microsoft Office AutoUpdate for Mac not working


If you installed Office 2016 for Mac back in September but haven’t been able to update the suite since, here’s a look at some troubleshooting tips.
I installed Office 2016 on Mac back in September, but I have not updated the suite since. Not a big deal, considering I have what needed to do with the suite. Yes, it’s a bad habit since updating the suite also protects the system from security issues. What ultimately forced me to try and resolve the problem was that I wanted to get the new feature updates, such as the new Full-Screen view in Outlook 2016, reliability, and performance upgrades.
Resolve Office AutoUpdate for Mac, not Working
To download the latest updates for Office 2016, I needed to have AutoUpdate version 3.4 installed. Unfortunately, checking for Updates from the Help menu was not working. I even tried to download the update manually, but Microsoft’s Support page behaved unresponsive, even in alternative web browsers.
It turns out the culprit was the DNS server Microsoft uses to connect to the public Internet. Either it’s a compatibility issue with OS XYosemite’s version, or Microsoft is not aware of the problem yet. The not-so-obvious solution I have found for this is to use Google’s public DNS address. Here is how you do it.
Launch System Preferences and go to Network > Advanced.
Next, click the DNS tab and then the Add (+) button at the bottom.
Now enter the following addresses: 8.8.8.8 and 8.8.4.4, then click OK.
Launch any of the Office apps, then click Help > Check for Updates, then click Install.
That’s it! You should now be back in business and be able to download and install the updates.
This solution might not be for everyone, but it’s worth a shot if you’re having a similar problem. Of course, you can always try downloading the AutoUpdate 3.4 update manually first to see if that will work. If not, then you can give the DNS entries a try.

You are welcome RC!

Andre, you’re the man! The DNS trick made it instantaneously. But how can it be so f… stupid? And how did you have the idea to investigate there? Great job:):):)

I have been noticing for weeks now OS X seems to be throttling my network downloads. In fact, I have been unable to download El Capitan because of this. I thought, since its affecting downloads, it must be something to do with how its connecting the Internet. Because I am not so familiar with the command line on the Mac, such as flush/dns on Windows, I researched if there was any alternative on for OS X. Came across Googles DNS solution.

That worked! I’ve been having this annoying problem for a long time.
I’m really upset that MS cannot correct this simple kind of problem. It seems as if they were doing that on purpose so that we would adopt the always up to date 365 version.
Anyways, thank you so much for saving me with this problem!
Maggie
Wow, wow. Just wanted to say Andre that you’re da man. Thanks for the great info.

This worked for me! I was unable to load Word 2016 after upgrading to osx 10.11.4 and unable to download the Office 365 updates until I used your DNS tip. Now everything has downloaded, installed, and is running perfectly! I use the Office suite every day–you’ve saved me a huge headache and lots of extra work. Thank you :)
Toby
Thank you kindly. Worked a treat. This has been annoying me for months!
Spencer
This is fantastic! I’d pretty much abandoned MS Office 365 because of the auto-update ‘hang’ problem. I found no solution that worked till I happened on this! Bravo!
Mike

I should let users know, if you join another network, these settings might be reset, so you will have apply them again.

On a 2016 Macbook pro – I thought it was a glitch in the hardware since it was a problem I’d never seen before. Thanks for solving it!
Ava
I didn’t realize this was for a 2016 Mac and I tried it with my old MacBook Pro. When I added the DNS numbers it deleted all of my others. Clicking on apps, it says I have no new updates! Now how do I get back my old DNS addresses? I’m worse off than I was. I can’t get updates and so I can’t update at all now! Help
Please ?
Ina
thanks for the tip! you are a genius!
Jeffy
Is not working for me on Office 2011. Sad face.
After I create the DNS connections the Help menu in Excel only goes to Autoupdate, Check for Updates and does not have an install menu. The response of Cannot Connect to Server does take a half-second longer than before. Smiley face.
I am considering uninstalling and then repurposing one of my 365 licenses to reinstall.

Beatrice Zelenko
what if the microsoft update is working but keeps showing Excel requires an update even after an update has been installed? any ideas?
Doug Acker
This does not work for me .. I can d/l the updates fine, but it gets stuck on the “installing” part so I don’t think it’s a DNS issue.
Andrew Jacobs
Worked perfectly
Mike
When I press the update button, i get a message “update already in progress” this is patently not so. Every now and again I get a message,”unable to install updates”
Damon
Did not work for me. All fields in the MSFT AutoUpdater app are disabled and I’m unable to execute anything. I can click on the links to the privacy notice, etc. However, Manual and Automatic options are disabled along with the “Check for Updates” button.
Regina
Install button at the very end of the process doesn’t show up :( What do I do? Neither is there an option for it while the Microsoft Autoupdate is on the dock, or on the task bar.
Julia
I have an older version of Office (2008) and these DNS codes don’t seem to work – also am using Mojave so not sure if this is also the problem. Are there different codes I can try?
Tony Powell
Its 2020 and this still works to get any microsoft program to launch so that you can activate the updater. I’m using office 365 for mac.
So thanks again for the tip!!!
