Almost a week ago OS X El Capitan was released to the public and in addition to the improvements that it brought with it at the time, it also has had certain "run-ins" with software that previously worked correctly in OS X Yosemite, an example of this we have in Office 2016, Microsoft's office suite.
Users of this Office 2016 for Mac They have experienced some serious errors when using the software, both Word, Excel, Outlook and PowerPoint are suffering freezes, even users with Office 2011 also have some other problem with Outlook in OS X El Capitan. Different publications have received complaints from said users in addition to an open thread on the Microsoft support website talking about the different problems.
Microsoft is aware of these problems with its software and has been responding to the different complaints of the users. In the open thread on the support website, the Microsoft Program Manager, Faisal Jeelani, stated that the company is working hard with Apple to solve these problems, but said that there is not yet a specific period of time to give a solution.
We know that some users may be experiencing problems with Office 2016 for Mac when running on El Capitan. We are actively investigating the matter with Apple. Until there is a solution, people are advised to install the latest Office 2016 for Mac updates using Microsoft AutoUpdate.
Problems range from random crashes, while other users they are not even able to open any program Office. On the other hand and in particular Outlook, the application with the most problems, even Office 2011 users in some cases cannot access their inboxes.
For now the only solution is to install a previous version, that is, Office 2011 (without using Outlook as a mail manager) and wait for Microsoft to release a definitive patch that fixes this situation to update again.
