Microsoft 2016 for Mac Products Crash When Opening

Anonymous

Hi there, my Outlook, Excel, and PowerPoint applications crash right after I open them. I can't even access the File/Help/etc menu because the Microsoft Error Reporting prompt opens immediately, and prevents the application's menu bar from opening. 

I'm using Mac Mojave v 10.14.3 - the most updated version - and as many have suggested, I went into Microsoft 'Check for Updates' through my Word application (the one that will open), and found I'm using the most updated version. 

I've also restarted my Mac and opened in safe mode with no difference.

Here are the crash logs below.

What should I do from here?

Thanks so much!

Hi Michael,

As you probably already know, the 16.16.8 update is now available and this problem has been fixed.

If you have AutoUpdate set to automatically install updates, it is likely this update was automatically installed.

If you have AutoUpdate set to manual updates, you can launch AutoUpdate from any Office application and choose Check for Updates from the Help menu. If none of your applications will open, you can download the update to AutoUpdate manually from this link, then install and run AutoUpdate, which will install the 16.16.8 fixed update to Microsoft Office 2016.

https://go.microsoft.com/fwlink/p/?linkid=830196

I highly recommend that anyone affected launch AutoUpdate by going to the Help menu in any Office 2016 application and choosing Check for Updates. Remove your installation from Insider programs by unchecking the box that has you join the program. There will never be any future Insider builds of Office for Office 2016. The feature set of Office 2016 is not going to change, and there will never be any future Insider builds.

    Note that if you DELETE these folders, you may lose data, so make sure you have a backup. Or, just rename the UBF8T346G9.Office folder and then try starting the Office apps.

    Note that, per my previous post, this will only get the Office apps to work ONCE; then they will crash again upon start up, unless you do one of the remedating things like locking the MicrosoftRegistrationDB.reg or re-installing with updates from the regular channel.

    Please read this whole thread to work-around the problem properly, and don't just delete your data without considering what you're doing. The UBF8T346G9.ms, UBF8T346G9.Office, and UBF8T346G9.OfficeOneDriveSyncIntegration folders will get automatically re-created, but they will not automatically have your data in them!

    When did the Insider program become 2019-only?

    I have ALWAYS used the Insider Fast channel to updates to 2016.

    The Insider program became 2019-only the day that Office 2019 was released.

    Insider builds have new features that will never be offered to 2016 users, and therefore 2016 users are not eligible for Insider builds.
