Dear Microsoft 365 Support Team,

I am experiencing an issue with Microsoft Word on my Mac.

Previously, I was able to use and edit documents normally. However, Word suddenly displayed the following message:

“Your account [[Moderator note: Personally Identifiable Information removed] @friendacc.com] doesn’t allow editing on a Mac.”

The account is a company Microsoft 365 account. Could you please help check whether the account has an active Microsoft 365 license that includes the desktop version of Microsoft Word for Mac?

Please also advise whether the issue may be related to account activation, license assignment, or a device activation problem.

Account: [[Moderator note: Personally Identifiable Information removed] @friendacc.com] Device: Mac Application: Microsoft Word

Thank you for your assistance.

Best regards, Panupak

    Hello @panupak churdchoo,

    Based on the information you provided, I understand that you are experiencing an issue with Microsoft Office applications on your Mac, where the apps unexpectedly enter read-only mode.

    This behavior may be related to a recent licensing update for Microsoft 365 Apps on macOS and iOS that took effect on July 13, 2026. Devices that are not running a supported version of the Microsoft 365 apps may enter reduced functionality mode, allowing users to open and view files but preventing them from editing, saving, or accessing the full set of features.

    You can find more information in the following Microsoft article: Certificate update for Microsoft 365 apps on managed macOS and iOS device

    Therefore, please update your Microsoft 365 applications to the latest supported version by following the instructions in: Update Microsoft 365 or Office on your macOS or iOS device | Microsoft Support

    Once the update has been completed, if the issue still persists, please try signing out of your work account within the Office applications and then signing back in. This will help ensure that the licensing information is refreshed and functioning correctly.

    Should you have any further questions or updates regarding this issue, please feel free to let me know. I look forward to hearing from you.
