Coming Soon: Box for Office v4.3.1217 & v4.4.1221

Box Employee
Box for Office v4.3.1217/v4.4.1221 will be released soon which reverts a change made in the prior release (Box for Office v4.1.1212/v4.2.1220) that defaulted Microsoft Office programs to use IE 11 via the FEATURE_BROWSER_EMULATION registry keys - Please see additional background below.  
 
This change by the prior release inadvertently affected other Microsoft Office add-ins. Unfortunately, due to limitations with our update process, we cannot revert back to the last set value. In order to prevent future issues, the new release to Box for Office v4.3.1217/v4.4.1221 will delete the Microsoft Office program registry values from the FEATURE_BROWSER_EMULATION registry keys.  
 
Admins who set Microsoft Office programs to use a non-default web browser control in the FEATURE_BROWSER_EMULATION registry keys prior to installing Box for Office v4.1.1212/v4.2.1220, may need to re-set their non-default web browser control after updating to Box for Office v4.3.1217/v4.4.1221
 
To facilitate this change, we will provide installers links to Box for Office v4.3.1217/v4.4.1221 before this version is pushed via our auto-update service. This will give you time to manually update to Box for Office v4.3.1217/v4.4.1221 and then re-apply your non-default FEATURE_BROWSER_EMULATION values.   
 
We apologize for any inconvenience this may cause, and if you have any questions, please reach out to the Box User Services team
 
Background
In the prior release, Box for Office v4.1.1212/v4.2.1220, we forced Microsoft Office programs to use IE 11 for any web browser controls used by the Office program. This was done by adding the Microsoft Office program executables (WinWord.exe, POWERPNT.EXE, outlook.exe, and EXCEL.EXE) as registry values under the following registry keys and setting the value data to be "11001": 
 
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
  • HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
 
For more information on the FEATURE_BROWSER_EMULATION settings, please read here.
By default, the Office program values do not exist under the keys above.
 
The update to Box for Office v4.3.1217/v4.4.1221 will delete the values (WinWord.exe, POWERPNT.EXE, outlook.exe, and EXCEL.EXE) from the locations above and revert the Microsoft Office programs back to using the default web browser control.
