OWA Updates help with Chrome issue in Office 365 but not for on-premises versions

By Tony Redmond,

By now you're probably well aware that Google depreciated the showModalDialog method in version 37 of their Chrome browser and caused some problems for Outlook Web App (OWA) and Exchange Administration Center (EAC), both of which use the method to display modal screens to collect user input. Well, there's good news and bad news to report on that topic.

Google remains adamant that the problem is with Microsoft's use of what Google considers to be an outdated and possibly insecure method. Google will fix problems in Chrome if they believe that they are real bugs - and proved that they would do so when fixing the recent issue that caused OWA to be unable to display calendar appointments.

The good news is that some relief is on the horizon because Microsoft is busily eliminating the use of the offending method. For example, the new OWA options implementation inside Office 365 introduces a different approach to displaying and gathering user options. So far I haven't encountered any problems using OWA with Chrome version 38, so that's a good sign - albeit a single-user test.


The bad news is that these OWA improvements are only available in Office 365 and there's no sign of similar progress in either EAC or OWA for on-premises Exchange yet. Don't hold your breath for an update in Exchange 2013 CU7 because I doubt that any change will happen there, even if its release was delayed last week.
