Microsoft Working on Fix for Office Bugs in OS X El Capitan

Since OS X El Capitan was released to the public last week, Microsoft Office users have noticed some serious bugs when attempting to use the software.

Word, Excel, Outlook, and PowerPoint are crashing for many Microsoft users who have installed Office 2016, and Office 2011 users are also noticing problems with Outlook. 

Microsoft is aware of the problems with its software and has been responding to customer complaints. In a thread on the Microsoft forums, Microsoft Program Manager Faisal Jeelani said the company is working with Apple to resolve the issues, but said there is no timeline for a fix. Microsoft also gave Computerworld a similar statement:
"We know that some users may be experiencing issues with Office 2016 for Mac running on El Capitan," the statement read. "We are actively investigating the matter with Apple. Until there is a fix, we recommend people install the latest updates to Office 2016 for Mac using Microsoft AutoUpdate."

Hello everyone,


We are aware of the issue with Outlook 2011 on El Capitan and of Office 2016 on El Capitan. 


We are working on a fix for 2011 and for 2016 we are working closely with Apple to resolve this issue as soon as possible. Unfortunately we do not have any timelines for either fix, please stay tuned and thank you for your understanding.
