Hi,
As many of us know, support for showModalDialog method in Google chrome will be ended starting May 2015 and so many things like attaching files in OWA won't work any more.
Till now, using this registry (group policy) solved the problem
https://support.microsoft.com/en-us/kb/3001145
but as it says, it is effective till tomorrow (May 1, 2015)
Is there any fix for this in exchange 2010 SP3 from Microsoft or we should say goodbye to using OWA with chrome (and I think you're on with me that using light mode of OWA is not a good workaround cause this mode has very limited capabilities and functionality)
Thanks
