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: 22.214.171.124 and 126.96.36.199, 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.
