Fix Chrome 37 and 38 issues with Outlook Web Access OWA on Linux

Chrome 37 and 38 have breaking changes with respect to OWA.  The popup dialogs don't appear, attachments don't work, and pasted URLs aren't properly formated.  More info here and here.

Basically Chrome has disabled modal dialogs.  You have to enable them to make OWA work properly with Chrome.

On Windows this is fixed with a registry setting and a group policy object.  On OSX you need to edit the plist file (see the comment section of the previous link).  On Linux, you must setup the Chrome policies directory and add a json file.

Here's the quick fix:
sudo mkdir -p /etc/opt/chrome/policies/managed
echo '{"EnableDeprecatedWebPlatformFeatures": ["ShowModalDialog_EffectiveUntil20150430"]}' | sudo tee /etc/opt/chrome/policies/managed/owafix.json
Apparently this fix is only good through April 2015, when this functionality will be completely removed from Chrome.

More information on managing Chrome policies can be found here.
