When you try to sent a new email and want to add an attachment nothing happens in google chrome. There is a simple fix for this issue and that is to simply run this .reg file: chrome-showmodaldialog Or change it yourself: [HKEY_CURRENT_USER\Software\Policies\Google\Chrome\EnableDeprecatedWebPlatformFeatures] “1”=”ShowModalDialog_EffectiveUntil20150430″ Re-open google chrome and the OWA and it should work!
