August 8, 2017, update for Word 2016 (KB3213656)

Applies to: Word 2016

This article describes update 3213656 for Microsoft Word 2016 that was released on August 8, 2017. This update has a prerequisite.

Be aware that the update on the Microsoft Download Center applies to the Microsoft Installer (.msi)-based edition of Office 2016. It doesn't apply to the Office 2016 Click-to-Run editions, such as Microsoft Office 365 Home. (How to determine?)

Known issues in this update

After you install this update 3213656, you may experience the following issues:

  • If you merge vertical cells in a table, the cell content disappears, and you can't select the merged cell.

  • If you open an existing document that has a table that contains merged cells, the cells are displayed as blank.

These issues occur only for users who receive Microsoft Office 2016 updates by using the Windows Installer (MSI) technology. If you have a Click-to-Run edition of Office, such as Office 365 Personal, you won't encounter these issues.


As a workaround, you can uninstall this update to restore your tables. We anticipate releasing the fix for these issues in the next monthly update that's tentatively scheduled for October 3, 2017. For more information, see the following Microsoft article:

After installing KB 3213656 or KB 4011039, merged table cells don't work correctly in Word or Outlook


To fix this issue, install the October 3, 2017, update for Word 2016 (KB4011140).

Improvements and fixes

This update fixes the following issues:

  • When you open a document that has a legacy shape in Word 2016, Word 2016 may freeze.

  • The hidden text isn't displayed even though the Print hidden text option is enabled in Word 2016.

  • Japanese characters in the vertical text may be displayed as square boxes in Word 2016.

  • Content with negative indent may be cropped in a non-first column in the presence of tables.

  • The manual hyphenation functionality does not work as expected in Word 2016. Not all words that could be hyphenated are actually hyphenated.

  • When you send an email with some spelling mistakes in Outlook 2016 in Windows 10, the regular proofing dialog isn't displayed as expected if the Always check spelling before sending option is enabled.

  • Assume that you have a Word document opened. When you open another document that has a task pane add-in embedded, the add-in is displayed in the first Word document.
