Office 365 Issue - How to Fix "Your Account Doesn't Allow Editing on a Mac"

Office 365 offers popular Microsoft products such as Word, Excel, Outlook, etc to its users. All of these products are among the most commonly used tools for document formatting, organization, and customization. Microsoft releases regular updates for its Office package so that users can have an optimal experience.

Because Office 365 is one of the newer subscription-based apps released by Microsoft it is updated all the time to remove any bugs and vulnerabilities and keep Microsoft's clients happy and satisfied.

However, some Mac users have pointed out that despite purchasing official licensed Office 365 software with up to date Mac software their documentation tools like Word have begun to crash unexpectedly and display error messages like: "Your account doesn't allow editing on a mac. To learn more, contact your Admin about your office plan." These user complaints say that all of the tools previously worked fine before Office 365 was installed.

How to fix the "Editing Not Allowed" error on Office Applications on Mac

The core of the problem comes from the software's (in)ability to detect correct licenses, which blocks paying users from editing their documents.
Also, Microsoft has spotted errors with certain files, which are causing the same error. We'll discuss the proper methods to remove these files and fix the error in this article. Read on if you have this issue.

Ensure that you have the correct license.

In order to make sure that you have an authentic license you must follow these. Once that has been verified you should proceed to the deletion of the files causing trouble. You can do that by
locating them in Finder and erasing them. Here's a detailed list:

  2. Click on the Settings icon and then click on Office 365.
  3. Press on Subscriptions.
  4. Next, look under the Licenses section to check if you have the latest desktop version of Office 365.
