Chrome 37 Breaks To and CC in Exchange 2010 OWA

Users may have noticed that after upgrading to Chrome 37 they can no longer click on the TO or CC buttons to access their contacts. This is caused by Chrome disabling support for the Modal Dialog tag that Microsoft uses to call the Address Book.

This issue can be fixed by making the following change to the registry:

In the Registry browse to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\

Create a folder titled EnableDeprecatedWebPlatformFeatures

Within the folder create a string value with name 1 and value ofShowModalDialog_EffectiveUntil20150430.

To check that this worked, browse to the chrome://policy URL.

Use Ctrl+Shift+R to "Reply all" to the selected message.
