Microsoft’s Office 2016 crashes like a banshee on Apple’s OS X El Capitan

“If you are a Mac user that relies on Office 2016 apps to get your day-to-day work done then you might want to hold off on upgrading to OS X El Capitan,” Adrian Kingsley-Hughes reports for ZDNet.

“According to an extensive thread on Microsoft’s Office for Mac support forum – combined with firsthand experience of the issue – the problems seem many and varied. Outlook appears to be the main culprit, but Excel and Word are also reported to be problematic for some,” Kingsley-Hughes reports. “For some the apps crash while in use, while for others it is coming out from sleep that causes issues.”

Kingsley-Hughes reports, “Others are finding that as soon as one app from the Office 2016 suite crashes or locks up, the others then follow suit.”

MacDailyNews Take: Microsoft. As ill-prepared and incompetent as ever.

Meanwhile, Mail, Pages, Numbers, and Keynote are working just fine for us. 100% Microsoft-free is the only way to fly!

Microsoft’s Office 2016 for Mac is wildly unstable on OS X El Capitan – September 30, 2015


  1. “In legend, a banshee is a fairy woman who begins to wail if someone is about to die.”

    MDN has it right. The banshee, she is wailing for the death of Office.

      1. Outlook is the ONLY MS Office app that’s crashing. Excel, Word, etc. all working just fine (as much as MS ever works fine). Other than that I love El Cap.

    1. I had to take all of my Outlook 2011 Exchange email and move it over to the Apple Mail app. Outlook 2011 crashes every single time I open it. Sometimes it will sync, then crash, sometimes it crashes right on startup, but it crashes every single time since the first El Cap beta. Tried every trick in the book (rebuilding db, moving files out to see what is causing it, etc.) and nothing works. Good news, the Mail app handles my Exchange mail just fine and now all of my email is in one place. Wish I’d moved it earlier 🙂

    2. My company runs Outlook 2011 which, according to our IT folks, doesn’t work well in the El Capitan. I’m afraid I don’t know specifics, so we’ll both need to search for more details.

      1. Some of us have no choice as the company has standardized on Microsoft Office. Oh we are told we can use other options, but there is no support and getting them to work with Exchange servers can be as big a trial as using Office!

  2. Are there any versions of Office that don’t crash. My one crashes if I dare copy anything from it at indeterminate times. Yet every other bit of software is rock solid. In some ways Microsoft can certainly be inventive.

  3. El Capitan has a much tighter security model. One item is preventing programs/users from altering /usr. A number of Unix and Unix type programs use /usr for executables, segments, libraries, etc; modifying /usr is no longer allowed.

  4. The *public* beta was out over a month ago. The *developers* beta, which Microsoft would’ve had access to, was available for even longer.

    As one of the largest vendors of *paid* office software for Mac, Microsoft has no excuse for it to be this bad.

  5. Been using Office 2016 on El Capitan for months without crashing. Only problem I have is slowness, slow to load and lag using the apps. I have older hardware from 2009, but they aren’t under powered junk. Mac Pro with 12GB ram, 2.66GHZ and Mac Pro 17″ 2.93Ghz, 8GB, and both have a 500GB SSD.

  6. Apple’s suite is great for light usage. Try doing work full time on a Mac with a normal enterprise. You can’t go Microsoft free. If you’re doing any serious work on documents or have a heavy dependency on your Mail / Calendar, you can’t just use Apple’s suite and mail.

    If you’re a SMB or a home user, all day every day. If you’re in a larger organization good luck.

    Office 2016 is fantastic on 10.10. Outlook is fantastic, outside of WebEx Plugin not supported but that is on Cisco. yes it does crash buy Office 11 is a disaster.

  7. To be fair, LOTS of apps aren’t ready for prime time, including Adobe’s Creative Suite.

    Still embarrassing for all publishers who couldn’t get their apps to run in the four months the Beta was available.
